# Dynamic Application Security Testing (DAST) **(ULTIMATE)**
If you deploy your web application into a new environment, your application may
become exposed to new types of attacks. For example, misconfigurations of your
application server or incorrect assumptions about security controls may not be
visible from the source code.
Dynamic Application Security Testing (DAST) examines applications for
vulnerabilities like these in deployed environments. DAST uses the open source
tool [OWASP Zed Attack Proxy](https://www.zaproxy.org/) for analysis.
NOTE:
To learn how four of the top six attacks were application-based and how
to protect your organization, download our
["A Seismic Shift in Application Security"](https://about.gitlab.com/resources/whitepaper-seismic-shift-application-security/)
whitepaper.
You can use DAST to examine your web applications:
- When initiated by a merge request, running as CI/CD pipeline job.
- On demand, outside the CI/CD pipeline.
After DAST creates its report, GitLab evaluates it for discovered
vulnerabilities between the source and target branches. Relevant
findings are noted in the merge request.
The comparison logic uses only the latest pipeline executed for the target
branch's base commit. Running the pipeline on other commits has no effect on
the merge request.
## Prerequisite
To use DAST, ensure you're using GitLab Runner with the
[`docker` executor](https://docs.gitlab.com/runner/executors/docker.html).
## Enable DAST
To enable DAST, either:
- Enable [Auto DAST](../../../topics/autodevops/stages.md#auto-dast) (provided
by [Auto DevOps](../../../topics/autodevops/index.md)).
- Manually [include the DAST template](#include-the-dast-template) in your existing
`.gitlab-ci.yml` file.
### Include the DAST template
If you want to manually add DAST to your application, the DAST job is defined
in a CI/CD template file. Updates to the template are provided with GitLab
upgrades, allowing you to benefit from any improvements and additions.
To include the DAST template:
1. Select the CI/CD template you want to use:
- [`DAST.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Security/DAST.gitlab-ci.yml):
Stable version of the DAST CI/CD template.
- [`DAST.latest.gitlab-ci.yml`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Security/DAST.latest.gitlab-ci.yml):
Latest version of the DAST template. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/254325)
in GitLab 13.8).
WARNING:
The latest version of the template may include breaking changes. Use the
stable template unless you need a feature provided only in the latest template.
For more information about template versioning, see the
[CI/CD documentation](../../../development/cicd/templates.md#latest-version).
1. Add a `dast` stage to your GitLab CI stages configuration:
```yaml
stages:
- dast
```
1. Add the template to GitLab, based on your version of GitLab:
- In GitLab 11.9 and later, [include](../../../ci/yaml/README.md#includetemplate)
the template by adding the following to your `.gitlab-ci.yml` file:
```yaml
include:
- template: <template_file.yml>
variables:
DAST_WEBSITE: https://example.com
```
- In GitLab 11.8 and earlier, add the contents of the template to your
`.gitlab_ci.yml` file.
1. Define the URL to be scanned by DAST by using one of these methods:
- Set the `DAST_WEBSITE` [CI/CD variable](../../../ci/yaml/README.md#variables).
If set, this value takes precedence.
- Add the URL in an `environment_url.txt` file at the root of your project. This is
useful for testing in dynamic environments. To run DAST against an application
dynamically created during a GitLab CI/CD pipeline, a job that runs prior to
the DAST scan must persist the application's domain in an `environment_url.txt`
file. DAST automatically parses the `environment_url.txt` file to find its
scan target.
For example, in a job that runs prior to DAST, you could include code that
looks similar to:
```yaml
script:
- echo http://${CI_PROJECT_ID}-${CI_ENVIRONMENT_SLUG}.domain.com > environment_url.txt
artifacts:
paths: [environment_url.txt]
when: always
```
You can see an example of this in our
[Auto DevOps CI YAML](https://gitlab.com/gitlab-org/gitlab/blob/master/lib/gitlab/ci/templates/Jobs/Deploy.gitlab-ci.yml)
file.
The included template creates a `dast` job in your CI/CD pipeline and scans
your project's running application for possible vulnerabilities.
The results are saved as a
[DAST report artifact](../../../ci/yaml/README.md#artifactsreportsdast)
that you can later download and analyze. Due to implementation limitations, we
always take the latest DAST artifact available. Behind the scenes, the
[GitLab DAST Docker image](https://gitlab.com/gitlab-org/security-products/dast)
is used to run the tests on the specified URL and scan it for possible
vulnerabilities.
By default, the DAST template uses the latest major version of the DAST Docker
image. Using the `DAST_VERSION` variable, you can choose how DAST updates:
- Automatically update DAST with new features and fixes by pinning to a major
version (such as `1`).
- Only update fixes by pinning to a minor version (such as `1.6`).
- Prevent all updates by pinning to a specific version (such as `1.6.4`).
Find the latest DAST versions on the [Releases](https://gitlab.com/gitlab-org/security-products/dast/-/releases)
page.
## Deployment options
Depending on the complexity of the target application, there are a few options as to how to deploy and configure
the DAST template. A set of example applications with their configurations have been made available in our
[DAST demonstrations](https://gitlab.com/gitlab-org/security-products/demos/dast/) project.
### Review Apps
Review Apps are the most involved method of deploying your DAST target application. To assist in the process,
we created a Review App deployment using Google Kubernetes Engine (GKE). This example can be found in our
[Review Apps - GKE](https://gitlab.com/gitlab-org/security-products/demos/dast/review-app-gke) project along with detailed
instructions in the [README.md](https://gitlab.com/gitlab-org/security-products/demos/dast/review-app-gke/-/blob/master/README.md)
on how to configure Review Apps for DAST.
### Docker Services
If your application utilizes Docker containers you have another option for deploying and scanning with DAST.
After your Docker build job completes and your image is added to your container registry, you can utilize the image as a
[service](../../../ci/services/index.md).
By using service definitions in your `gitlab-ci.yml`, you can scan services with the DAST analyzer.
```yaml
stages:
- build
- dast
include:
- template: DAST.gitlab-ci.yml
# Deploys the container to the GitLab container registry
deploy:
services:
- name: docker:dind
alias: dind
image: docker:19.03.5
stage: build
script:
- docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
- docker pull $CI_REGISTRY_IMAGE:latest || true
- docker build --tag $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA --tag $CI_REGISTRY_IMAGE:latest .
- docker push $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA
- docker push $CI_REGISTRY_IMAGE:latest
services: # use services to link your app container to the dast job
- name: $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA
alias: yourapp
variables:
DAST_FULL_SCAN_ENABLED: "true" # do a full scan
DAST_ZAP_USE_AJAX_SPIDER: "true" # use the ajax spider
```
Most applications depend on multiple services such as databases or caching services. By default, services defined in the services fields cannot communicate
with each another. To allow communication between services, enable the `FF_NETWORK_PER_BUILD` [feature flag](https://docs.gitlab.com/runner/configuration/feature-flags.html#available-feature-flags).
```yaml
variables:
FF_NETWORK_PER_BUILD: "true" # enable network per build so all services can communicate on the same network
services: # use services to link the container to the dast job
- name: mongo:latest
alias: mongo
- name: $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA
alias: yourapp
```
### DAST application analysis
DAST can analyze applications in two ways:
- Passive scan only (DAST default). DAST executes
[ZAP's Baseline Scan](https://www.zaproxy.org/docs/docker/baseline-scan/) and doesn't
actively attack your application.
- Passive and active scan. DAST can be [configured](#full-scan) to also perform an active scan
to attack your application and produce a more extensive security report. It can be very
useful when combined with [Review Apps](../../../ci/review_apps/index.md).
Note that a pipeline may consist of multiple jobs, including SAST and DAST scanning. If any job
fails to finish for any reason, the security dashboard doesn't show DAST scanner output. For
example, if the DAST job finishes but the SAST job fails, the security dashboard doesn't show DAST
results. On failure, the analyzer outputs an
[exit code](../../../development/integrations/secure.md#exit-code).
#### DAST job order
When using the `DAST.gitlab-ci.yml` template, the `dast` job is run last as shown in
the example below. To ensure DAST is scanning the latest code, your CI pipeline
should deploy changes to the web server in one of the jobs preceding the `dast` job.
```yaml
stages:
- build
- test
- deploy
- dast
```
Be aware that if your pipeline is configured to deploy to the same webserver in
each run, running a pipeline while another is still running could cause a race condition
where one pipeline overwrites the code from another pipeline. The site to be scanned
should be excluded from changes for the duration of a DAST scan.
The only changes to the site should be from the DAST scanner. Be aware that any
changes that users, scheduled tasks, database changes, code changes, other pipelines, or other scanners make to
the site during a scan could lead to inaccurate results.
### Hide sensitive information
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/36332) in GitLab 13.1.
HTTP request and response headers may contain sensitive information, including cookies and
authorization credentials. By default, the following headers are masked:
- `Authorization`.
- `Proxy-Authorization`.
- `Set-Cookie` (values only).
- `Cookie` (values only).
Using the [`DAST_MASK_HTTP_HEADERS` CI/CD variable](#available-variables), you can list the
headers whose values you want masked. For details on how to mask headers, see
[Customizing the DAST settings](#customizing-the-dast-settings).
### Authentication
It's also possible to authenticate the user before performing the DAST checks.
NOTE:
We highly recommended that you configure the scanner to authenticate to the application,
otherwise it cannot check most of the application for security risks, as most
of your application is likely not accessible without authentication. It is also recommended
that you periodically confirm the scanner's authentication is still working as this tends to break over
time due to authentication changes to the application.
Create masked CI/CD variables to pass the credentials that DAST uses.
To create masked variables for the username and password, see [Create a custom variable in the UI](../../../ci/variables/README.md#custom-cicd-variables).
Note that the key of the username variable must be `DAST_USERNAME`
and the key of the password variable must be `DAST_PASSWORD`.
After DAST has authenticated with the application, all cookies are collected from the web browser.
For each cookie a matching session token is created for use by ZAP. This ensures ZAP is recognized
by the application as correctly authenticated.
Other variables that are related to authenticated scans are:
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_WEBSITE: https://example.com
DAST_AUTH_URL: https://example.com/sign-in
DAST_USERNAME_FIELD: session[user] # the name of username field at the sign-in HTML form
DAST_PASSWORD_FIELD: session[password] # the name of password field at the sign-in HTML form
DAST_SUBMIT_FIELD: login # the `id` or `name` of the element that when clicked will submit the login form or the password form of a multi-page login process
DAST_FIRST_SUBMIT_FIELD: next # the `id` or `name` of the element that when clicked will submit the username form of a multi-page login process
DAST_EXCLUDE_URLS: http://example.com/sign-out,http://example.com/sign-out-2 # optional, URLs to skip during the authenticated scan; comma-separated, no spaces in between
DAST_AUTH_VERIFICATION_URL: http://example.com/loggedin_page # optional, a URL only accessible to logged in users that DAST can use to confirm successful authentication
```
The results are saved as a
[DAST report artifact](../../../ci/yaml/README.md#artifactsreportsdast)
that you can later download and analyze.
Due to implementation limitations, we always take the latest DAST artifact available.
WARNING:
**NEVER** run an authenticated scan against a production server. When an authenticated
scan is run, it may perform *any* function that the authenticated user can. This
includes actions like modifying and deleting data, submitting forms, and following links.
Only run an authenticated scan against a test server.
### Full scan
DAST can be configured to perform [ZAP Full Scan](https://github.com/zaproxy/zaproxy/wiki/ZAP-Full-Scan), which
includes both passive and active scanning against the same target website:
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_FULL_SCAN_ENABLED: "true"
```
If your DAST job exceeds the job timeout and you need to reduce the scan duration, we shared some
tips for optimizing DAST scans in a [blog post](https://about.gitlab.com/blog/2020/08/31/how-to-configure-dast-full-scans-for-complex-web-applications/).
#### Domain validation
WARNING:
In GitLab 13.8, domain validation, outside of the new on-demand scan site profile validation, was deprecated. In GitLab 14.0, domain validation in CI/CD jobs will be permanently removed.
The DAST job can be run anywhere, which means you can accidentally hit live web servers
and potentially damage them. You could even take down your production environment.
For that reason, you should use domain validation.
Domain validation is not required by default. It can be required by setting the
[CI/CD variable](#available-variables) `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` to `"true"`.
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_FULL_SCAN_ENABLED: "true"
DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED: "true"
```
Since ZAP full scan actively attacks the target application, DAST sends a ping
to the target (normally defined in `DAST_WEBSITE` or `environment_url.txt`) beforehand.
- If `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` is `false` or unset, the scan
proceeds unless the response to the ping includes a `Gitlab-DAST-Permission`
header with a value of `deny`.
- If `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` is `true`, the scan exits
unless the response to the ping includes a `Gitlab-DAST-Permission` header with
a value of `allow`.
Here are some examples of adding the `Gitlab-DAST-Permission` header to a response
in Rails, Django, and Node (with Express).
##### Ruby on Rails
Here's how you would add a
[custom header in Ruby on Rails](https://guides.rubyonrails.org/action_controller_overview.html#setting-custom-headers):
```ruby
class DastWebsiteTargetController < ActionController::Base
def dast_website_target
response.headers['Gitlab-DAST-Permission'] = 'allow'
head :ok
end
end
```
##### Django
Here's how you would add a
[custom header in Django](https://docs.djangoproject.com/en/2.2/ref/request-response/#setting-header-fields):
```python
class DastWebsiteTargetView(View):
def head(self, *args, **kwargs):
response = HttpResponse()
response['Gitlab-Dast-Permission'] = 'allow'
return response
```
##### Node (with Express)
Here's how you would add a
[custom header in Node (with Express)](http://expressjs.com/en/5x/api.html#res.append):
```javascript
app.get('/dast-website-target', function(req, res) {
res.append('Gitlab-DAST-Permission', 'allow')
res.send('Respond to DAST ping')
})
```
##### Domain validation header via a proxy
It's also possible to add the `Gitlab-DAST-Permission` header via a proxy.
###### NGINX
The following configuration allows NGINX to act as a reverse proxy and add the
`Gitlab-DAST-Permission` [header](http://nginx.org/en/docs/http/ngx_http_headers_module.html#add_header):
```nginx
# default.conf
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://test-application;
add_header Gitlab-DAST-Permission allow;
}
}
```
###### Apache
Apache can also be used as a [reverse proxy](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html)
to add the `Gitlab-DAST-Permission` [header](https://httpd.apache.org/docs/current/mod/mod_headers.html).
To do so, add the following lines to `httpd.conf`:
```plaintext
# httpd.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_http_module modules/mod_proxy_http.so
<VirtualHost *:80>
ProxyPass "/" "http://test-application.com/"
ProxyPassReverse "/" "http://test-application.com/"
Header set Gitlab-DAST-Permission "allow"
</VirtualHost>
```
[This snippet](https://gitlab.com/gitlab-org/security-products/dast/snippets/1894732) contains a complete `httpd.conf` file
configured to act as a remote proxy and add the `Gitlab-DAST-Permission` header.
### API scan
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/10928) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 12.10.
Using an API specification as a scan's target is a useful way to seed URLs for scanning an API.
Vulnerability rules in an API scan are different than those in a normal website scan.
#### Specification format
API scans support OpenAPI V2 and OpenAPI V3 specifications. You can define these specifications using `JSON` or `YAML`.
#### Import API specification from a URL
If your API specification is accessible at a URL, you can pass that URL in directly as the target.
The specification does not have to be hosted on the same host as the API being tested.
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_API_SPECIFICATION: http://my.api/api-specification.yml
```
#### Import API specification from a file
If your API specification file is in your repository, you can provide its filename as the target.
The API specification file must be in the `/zap/wrk` directory.
```yaml
dast:
before_script:
- mkdir -p /zap/wrk
- cp api-specification.yml /zap/wrk/api-specification.yml
variables:
GIT_STRATEGY: fetch
DAST_API_SPECIFICATION: api-specification.yml
```
#### Full API scan
API scans support full scanning, which can be enabled by using the `DAST_FULL_SCAN_ENABLED`
CI/CD variable. Domain validation is not supported for full API scans.
#### Host override
Specifications often define a host, which contains a domain name and a port. The
host referenced may be different than the host of the API's review instance.
This can cause incorrect URLs to be imported, or a scan on an incorrect host.
Use the `DAST_API_HOST_OVERRIDE` CI/CD variable to override these values.
WARNING:
When using the API host override feature, you cannot use the `$DAST_WEBSITE` variable to override the hostname.
A host override is _only_ supported when importing the API specification from a URL. Attempts to override the
host throw an error when the API specification is imported from a file. This is due to a limitation in the
ZAP OpenAPI extension.
For example, with a OpenAPI V3 specification containing:
```yaml
servers:
- url: https://api.host.com
```
If the test version of the API is running at `https://api-test.host.com`, then
the following DAST configuration can be used:
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_API_SPECIFICATION: http://api-test.host.com/api-specification.yml
DAST_API_HOST_OVERRIDE: api-test.host.com
```
#### Authentication using headers
Tokens in request headers are often used as a way to authenticate API requests.
You can achieve this by using the `DAST_REQUEST_HEADERS` CI/CD variable.
Headers are applied to every request DAST makes.
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_API_SPECIFICATION: http://api-test.api.com/api-specification.yml
DAST_REQUEST_HEADERS: "Authorization: Bearer my.token"
```
### URL scan
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/214120) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.4.
> - [Improved](https://gitlab.com/gitlab-org/gitlab/-/issues/273141) in GitLab 13.11.
A URL scan allows you to specify which parts of a website are scanned by DAST.
#### Define the URLs to scan
URLs to scan can be specified by either of the following methods:
- Use `DAST_PATHS_FILE` CI/CD variable to specify the name of a file containing the paths.
- Use `DAST_PATHS` variable to list the paths.
##### Use `DAST_PATHS_FILE` CI/CD variable
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/258825) in GitLab 13.6.
To define the URLs to scan in a file, create a plain text file with one path per line.
```plaintext
page1.html
/page2.html
category/shoes/page1.html
```
To scan the URLs in that file, set the CI/CD variable `DAST_PATHS_FILE` to the path of that file.
The file can be checked into the project repository or generated as an artifact by a job that
runs before DAST.
By default, DAST scans do not clone the project repository. Instruct the DAST job to clone
the project by setting `GIT_STRATEGY` to fetch. Give a file path relative to `CI_PROJECT_DIR` to `DAST_PATHS_FILE`.
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
GIT_STRATEGY: fetch
DAST_PATHS_FILE: url_file.txt # url_file.txt lives in the root directory of the project
```
##### Use `DAST_PATHS` CI/CD variable
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/214120) in GitLab 13.4.
To specify the paths to scan in a CI/CD variable, add a comma-separated list of the paths to the `DAST_PATHS`
variable. Note that you can only scan paths of a single host.
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_PATHS: "/page1.html,/category1/page1.html,/page3.html"
```
When using `DAST_PATHS` and `DAST_PATHS_FILE`, note the following:
- `DAST_WEBSITE` must be defined when using either `DAST_PATHS_FILE` or `DAST_PATHS`. The paths listed in either use `DAST_WEBSITE` to build the URLs to scan
- Spidering is disabled when `DAST_PATHS` or `DAST_PATHS_FILE` are defined
- `DAST_PATHS_FILE` and `DAST_PATHS` can not be used together
- The `DAST_PATHS` variable has a limit of about 130kb. If you have a list or paths
greater than this, use `DAST_PATHS_FILE`.
#### Full Scan
To perform a [full scan](#full-scan) on the listed paths, use the `DAST_FULL_SCAN_ENABLED` CI/CD variable.
### Customizing the DAST settings
WARNING:
Beginning in GitLab 13.0, the use of [`only` and `except`](../../../ci/yaml/README.md#onlyexcept-basic)
is no longer supported. When overriding the template, you must use [`rules`](../../../ci/yaml/README.md#rules) instead.
The DAST settings can be changed through CI/CD variables by using the
[`variables`](../../../ci/yaml/README.md#variables) parameter in `.gitlab-ci.yml`.
These variables are documented in [available variables](#available-variables).
For example:
```yaml
include:
- template: DAST.gitlab-ci.yml
variables:
DAST_WEBSITE: https://example.com
DAST_SPIDER_MINS: 120
```
Because the template is [evaluated before](../../../ci/yaml/README.md#include) the pipeline
configuration, the last mention of the variable takes precedence.
### Available variables
DAST can be [configured](#customizing-the-dast-settings) using CI/CD variables.
| CI/CD variable | Type | Description |
|------------------------------| --------|-------------|
| `SECURE_ANALYZERS_PREFIX` | URL | Set the Docker registry base address from which to download the analyzer. |
| `DAST_WEBSITE` | URL | The URL of the website to scan. `DAST_API_SPECIFICATION` must be specified if this is omitted. |

| `DAST_SPIDER_START_AT_HOST` | boolean | Set to `false` to prevent DAST from resetting the target to its host before scanning. When `true`, non-host targets `http://test.site/some_path` is reset to `http://test.site` before scan. Default: `true`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/258805) in GitLab 13.6. |
| `DAST_AUTH_URL` | URL | The URL of the page containing the sign-in HTML form on the target website. `DAST_USERNAME` and `DAST_PASSWORD` are submitted with the login form to create an authenticated scan. Not supported for API scans. |
| `DAST_AUTH_VERIFICATION_URL` | URL | A URL only accessible to logged in users that DAST can use to confirm successful authentication. If provided, DAST will exit if it cannot access the URL. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/207335) in GitLab 13.8.
| `DAST_USERNAME` | string | The username to authenticate to in the website. |
| `DAST_PASSWORD` | string | The password to authenticate to in the website. |
| `DAST_USERNAME_FIELD` | string | The name of username field at the sign-in HTML form. |
| `DAST_PASSWORD_FIELD` | string | The name of password field at the sign-in HTML form. |
| `DAST_SKIP_TARGET_CHECK` | boolean | Set to `true` to prevent DAST from checking that the target is available before scanning. Default: `false`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/229067) in GitLab 13.8. |
| `DAST_MASK_HTTP_HEADERS` | string | Comma-separated list of request and response headers to be masked (GitLab 13.1). Must contain **all** headers to be masked. Refer to [list of headers that are masked by default](#hide-sensitive-information). |
| `DAST_EXCLUDE_URLS` | URLs | The URLs to skip during the authenticated scan; comma-separated. Regular expression syntax can be used to match multiple URLs. For example, `.*` matches an arbitrary character sequence. Not supported for API scans. |
| `DAST_FULL_SCAN_ENABLED` | boolean | Set to `true` to run a [ZAP Full Scan](https://github.com/zaproxy/zaproxy/wiki/ZAP-Full-Scan) instead of a [ZAP Baseline Scan](https://github.com/zaproxy/zaproxy/wiki/ZAP-Baseline-Scan). Default: `false` |
| `DAST_FULL_SCAN_DOMAIN_VALIDATION_REQUIRED` | boolean | [Deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/293595) in GitLab 13.8, to be removed in 14.0. Set to `true` to require [domain validation](#domain-validation) when running DAST full scans. Not supported for API scans. Default: `false` |
| `DAST_AUTO_UPDATE_ADDONS` | boolean | ZAP add-ons are pinned to specific versions in the DAST Docker image. Set to `true` to download the latest versions when the scan starts. Default: `false` |
| `DAST_API_HOST_OVERRIDE` | string | Used to override domains defined in API specification files. Only supported when importing the API specification from a URL. Example: `example.com:8080` |
| `DAST_EXCLUDE_RULES` | string | Set to a comma-separated list of Vulnerability Rule IDs to exclude them from running during the scan. Rule IDs are numbers and can be found from the DAST log or on the [ZAP project](https://github.com/zaproxy/zaproxy/blob/develop/docs/scanners.md). For example, `HTTP Parameter Override` has a rule ID of `10026`. **Note:** In earlier versions of GitLab the excluded rules were executed but alerts they generated were suppressed. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/118641) in GitLab 12.10. |
| `DAST_REQUEST_HEADERS` | string | Set to a comma-separated list of request header names and values. Headers are added to every request made by DAST. For example, `Cache-control: no-cache,User-Agent: DAST/1.0` |

| `DAST_HTML_REPORT` | string | The filename of the HTML report written at the end of a scan. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12652) in GitLab 13.1. |
| `DAST_MARKDOWN_REPORT` | string | The filename of the Markdown report written at the end of a scan. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12652) in GitLab 13.1.|
| `DAST_XML_REPORT` | string | The filename of the XML report written at the end of a scan. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12652) in GitLab 13.1. |
| `DAST_INCLUDE_ALPHA_VULNERABILITIES` | boolean | Set to `true` to include alpha passive and active scan rules. Default: `false`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12652) in GitLab 13.1. |
| `DAST_USE_AJAX_SPIDER` | boolean | Set to `true` to use the AJAX spider in addition to the traditional spider, useful for crawling sites that require JavaScript. Default: `false`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12652) in GitLab 13.1. |
| `DAST_PATHS` | string | Set to a comma-separated list of URLs for DAST to scan. For example, `/page1.html,/category1/page3.html,/page2.html`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/214120) in GitLab 13.4. |

The URLs to skip during the authenticated scan; comma-separated. Regular expression syntax can be used to match multiple URLs. For example, `.*` matches an arbitrary character sequence. Not supported for API scans. |
### DAST command-line options
Not all DAST configuration is available via CI/CD variables. To find out all
possible options, run the following configuration.
Available command-line options are printed to the job log:
```yaml
include:
template: DAST.gitlab-ci.yml
dast:
script:
- /analyze --help
```
You must then overwrite the `script` command to pass in the appropriate
argument. For example, vulnerability definitions in alpha can be included with
`-a`. The following configuration includes those definitions:
```yaml
include:
template: DAST.gitlab-ci.yml
dast:
script:
- export DAST_WEBSITE=${DAST_WEBSITE:-$(cat environment_url.txt)}
- /analyze -a -t $DAST_WEBSITE
```
### Custom ZAProxy configuration
The ZAProxy server contains many [useful configurable values](https://gitlab.com/gitlab-org/gitlab/-/issues/36437#note_245801885).
Many key/values for `-config` remain undocumented, but there is an untested list of
[possible keys](https://gitlab.com/gitlab-org/gitlab/-/issues/36437#note_244981023).
Note that these options are not supported by DAST, and may break the DAST scan
when used. An example of how to rewrite the Authorization header value with `TOKEN` follows:
```yaml
include:
template: DAST.gitlab-ci.yml
variables:
DAST_ZAP_CLI_OPTIONS: "-config replacer.full_list(0).description=auth -config replacer.full_list(0).enabled=true -config replacer.full_list(0).matchtype=REQ_HEADER -config replacer.full_list(0).matchstr=Authorization -config replacer.full_list(0).regex=false -config replacer.full_list(0).replacement=TOKEN"
```
### Bleeding-edge vulnerability definitions
ZAP first creates rules in the `alpha` class. After a testing period with
the community, they are promoted to `beta`. DAST uses `beta` definitions by
default. To request `alpha` definitions, use the
`DAST_INCLUDE_ALPHA_VULNERABILITIES` CI/CD variable as shown in the
following configuration:
```yaml
include:
template: DAST.gitlab-ci.yml
variables:
DAST_INCLUDE_ALPHA_VULNERABILITIES: "true"
```
### Cloning the project's repository
The DAST job does not require the project's repository to be present when running, so by default
[`GIT_STRATEGY`](../../../ci/runners/README.md#git-strategy) is set to `none`.
### Debugging DAST jobs
A DAST job has two executing processes:
- The ZAP server.
- A series of scripts that start, control and stop the ZAP server.
Debug mode of the scripts can be enabled by using the `DAST_DEBUG` CI/CD variable. This can help when troubleshooting the job,
and outputs statements indicating what percentage of the scan is complete.
For details on using variables, see [Overriding the DAST template](#customizing-the-dast-settings).
Debug mode of the ZAP server can be enabled using the `DAST_ZAP_LOG_CONFIGURATION` variable.
The following table outlines examples of values that can be set and the effect that they have on the output that is logged.
Multiple values can be specified, separated by semicolons.
| Log configuration value | Effect |
|-------------------------------------------------- | ----------------------------------------------------------------- |
| `log4j.rootLogger=DEBUG` | Enable all debug logging statements. |
| `log4j.logger.org.apache.commons.httpclient=DEBUG` | Log every HTTP request and response made by the ZAP server. |
| `log4j.logger.org.zaproxy.zap.spider.SpiderController=DEBUG` | Log URLs found during the spider scan of the target. |
| `log4j.logger.com.crawljax=DEBUG` | Enable Ajax Crawler debug logging statements. |
| `log4j.logger.org.parosproxy.paros=DEBUG` | Enable ZAP server proxy debug logging statements. |
| `log4j.logger.org.zaproxy.zap=DEBUG` | Enable debug logging statements of the general ZAP server code. |
## Running DAST in an offline environment
For self-managed GitLab instances in an environment with limited, restricted, or intermittent access
to external resources through the internet, some adjustments are required for the DAST job to
successfully run. For more information, see [Offline environments](../offline_deployments/index.md).
### Requirements for offline DAST support
To use DAST in an offline environment, you need:
- GitLab Runner with the [`docker` or `kubernetes` executor](#prerequisite).
- Docker Container Registry with a locally available copy of the DAST
[container image](https://gitlab.com/gitlab-org/security-products/dast), found in the
[DAST container registry](https://gitlab.com/gitlab-org/security-products/dast/container_registry).
Note that GitLab Runner has a [default `pull policy` of `always`](https://docs.gitlab.com/runner/executors/docker.html#using-the-always-pull-policy),
meaning the runner tries to pull Docker images from the GitLab container registry even if a local
copy is available. The GitLab Runner [`pull_policy` can be set to `if-not-present`](https://docs.gitlab.com/runner/executors/docker.html#using-the-if-not-present-pull-policy)
in an offline environment if you prefer using only locally available Docker images. However, we
recommend keeping the pull policy setting to `always` if not in an offline environment, as this
enables the use of updated scanners in your CI/CD pipelines.
### Make GitLab DAST analyzer images available inside your Docker registry
For DAST, import the following default DAST analyzer image from `registry.gitlab.com` to your [local Docker container registry](../../packages/container_registry/index.md):
- `registry.gitlab.com/gitlab-org/security-products/dast:latest`
The process for importing Docker images into a local offline Docker registry depends on
**your network security policy**. Please consult your IT staff to find an accepted and approved
process by which external resources can be imported or temporarily accessed. Note
that these scanners are [updated periodically](../index.md#maintenance-and-update-of-the-vulnerabilities-database)
with new definitions, so consider if you're able to make periodic updates yourself.
For details on saving and transporting Docker images as a file, see Docker's documentation on
[`docker save`](https://docs.docker.com/engine/reference/commandline/save/),
[`docker load`](https://docs.docker.com/engine/reference/commandline/load/),
[`docker export`](https://docs.docker.com/engine/reference/commandline/export/), and
[`docker import`](https://docs.docker.com/engine/reference/commandline/import/).
### Set DAST CI/CD job variables to use local DAST analyzers
Add the following configuration to your `.gitlab-ci.yml` file. You must replace `image` to refer to
the DAST Docker image hosted on your local Docker container registry:
```yaml
include:
- template: DAST.gitlab-ci.yml
dast:
image: registry.example.com/namespace/dast:latest
```
The DAST job should now use local copies of the DAST analyzers to scan your code and generate
security reports without requiring internet access.
Alternatively, you can use the CI/CD variable `SECURE_ANALYZERS_PREFIX` to override the base registry address of the `dast` image.
## On-demand scans
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/218465) in GitLab 13.2.
> - [Improved](https://gitlab.com/gitlab-org/gitlab/-/issues/218465) in GitLab 13.3.
> - The saved scans feature was [introduced](https://gitlab.com/groups/gitlab-org/-/epics/5100) in GitLab 13.9.
> - The option to select a branch was [introduced](https://gitlab.com/groups/gitlab-org/-/epics/4847) in GitLab 13.10.
> - DAST branch selection [feature flag removed](https://gitlab.com/gitlab-org/gitlab/-/issues/322672) in GitLab 13.11.
An on-demand DAST scan runs outside the DevOps life cycle. Changes in your repository don't trigger
the scan. You must start it manually.
An on-demand DAST scan:
- Can run a specific combination of a [site profile](#site-profile) and a
[scanner profile](#scanner-profile).
- Is associated with your project's default branch.
- Is saved on creation so it can be run later.
In GitLab 13.10 and later, you can select to run an on-demand scan against a specific branch.
### On-demand scan modes
An on-demand scan can be run in active or passive mode:
- _Passive mode_ is the default and runs a ZAP Baseline Scan.
- _Active mode_ runs a ZAP Full Scan which is potentially harmful to the site being scanned. To
minimize the risk of accidental damage, running an active scan requires a [validated site
profile](#site-profile-validation).
### Run an on-demand DAST scan
NOTE:
You must have permission to run an on-demand DAST scan against a protected branch.
The default branch is automatically protected. For more information, see
[Pipeline security on protected branches](../../../ci/pipelines/index.md#pipeline-security-on-protected-branches).
Prerequisites:
- A [scanner profile](#create-a-scanner-profile).
- A [site profile](#create-a-site-profile).
- If you are running an active scan the site profile must be [validated](#validate-a-site-profile).
To run an on-demand scan, either:
- [Create and run an on-demand scan](#create-and-run-an-on-demand-scan).
- [Run a previously saved on-demand scan](#run-a-saved-on-demand-scan).
#### Create and run an on-demand scan

### Site profile
A site profile describes the attributes of a web site to scan on demand with DAST. A site profile is
required for an on-demand DAST scan.
A site profile contains the following:
- **Profile name**: A name you assign to the site to be scanned.
- **Target URL**: The URL that DAST runs against.
- **Excluded URLs**: A comma-separated list of URLs to exclude from the scan.
- **Request headers**: A comma-separated list of HTTP request headers, including names and values. These headers are added to every request made by DAST.
- **Authentication**:
- **Authenticated URL**: The URL of the page containing the sign-in HTML form on the target website. The username and password are submitted with the login form to create an authenticated scan.
- **Username**: The username used to authenticate to the website.
- **Password**: The password used to authenticate to the website.
- **Username form field**: The name of username field at the sign-in HTML form.
- **Password form field**: The name of password field at the sign-in HTML form.
#### Site profile validation
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/233020) in GitLab 13.8.
Site profile validation reduces the risk of running an active scan against the wrong website. A site
must be validated before an active scan can run against it. The site validation methods are as
follows:
- _Text file validation_ requires a text file be uploaded to the target site. The text file is
allocated a name and content that is unique to the project. The validation process checks the
file's content.
- _Header validation_ requires the header `Gitlab-On-Demand-DAST` be added to the target site,
with a value unique to the project. The validation process checks that the header is present, and
checks its value.
Both methods are equivalent in functionality. Use whichever is feasible.
#### Create a site profile
To create a site profile:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. Select **Manage** in the **DAST Profiles** row.
1. Select **New > Site Profile**.
1. Complete the fields then select **Save profile**.
The site profile is created.
#### Edit a site profile
To edit an existing site profile:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. In the **DAST Profiles** row select **Manage**.
1. Select the **Site Profiles** tab.
1. In the profile's row select the **More actions** (**{ellipsis_v}**) menu, then select **Edit**.
1. Edit the fields then select **Save profile**.
If a site profile is linked to a security policy, a user cannot edit the profile from this page. See
[Scan Policies](../policies/index.md)
for more information.
#### Delete a site profile
To delete an existing site profile:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. In the **DAST Profiles** row select **Manage**.
1. Select the **Site Profiles** tab.
1. In the profile's row select the **More actions** (**{ellipsis_v}**) menu, then select **Delete**.
1. Select **Delete** to confirm the deletion.
If a site profile is linked to a security policy, a user cannot delete the profile from this page.
See [Scan Policies](../policies/index.md)
for more information.
#### Validate a site profile
Prerequisites:
- A site profile.
To validate a site profile:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. In the **DAST Profiles** row select **Manage**.
1. Select the **Site Profiles** tab.
1. In the profile's row select **Validate** or **Retry validation**.
1. Select the validation method.
1. For **Text file validation**:
1. Download the validation file listed in **Step 2**.
1. Upload the validation file to the host. Upload the file to the location in
**Step 3** or any location you prefer.
1. Select **Validate**.
1. For **Header validation**:
1. Select the clipboard icon in **Step 2**.
1. Edit the header of the site to validate, and paste the clipboard content.
1. Select the input field in **Step 3** and enter the location of the header.
1. Select **Validate**.
The site is validated and an active scan can run against it.
If a validated site profile's target URL is edited, the site's validation status is revoked.
#### Revoke a site profile's validation status
Note that all site profiles with the same URL have their validation status revoked.
To revoke a site profile's validation status:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. In the **DAST Profiles** row select **Manage**.
1. Select **Revoke validation** beside the validated profile.
The site profile's validation status is revoked.
#### Validated site profile headers
The following are code samples of how you can provide the required site profile header in your
application.
##### Ruby on Rails example for on-demand scan
Here's how you can add a custom header in a Ruby on Rails application:
```ruby
class DastWebsiteTargetController < ActionController::Base
def dast_website_target
response.headers['Gitlab-On-Demand-DAST'] = '0dd79c9a-7b29-4e26-a815-eaaf53fcab1c'
head :ok
end
end
```
##### Django example for on-demand scan
Here's how you can add a
[custom header in Django](https://docs.djangoproject.com/en/2.2/ref/request-response/#setting-header-fields):
```python
class DastWebsiteTargetView(View):
def head(self, *args, **kwargs):
response = HttpResponse()
response['Gitlab-On-Demand-DAST'] = '0dd79c9a-7b29-4e26-a815-eaaf53fcab1c'
return response
```
##### Node (with Express) example for on-demand scan
Here's how you can add a
[custom header in Node (with Express)](http://expressjs.com/en/5x/api.html#res.append):
```javascript
app.get('/dast-website-target', function(req, res) {
res.append('Gitlab-On-Demand-DAST', '0dd79c9a-7b29-4e26-a815-eaaf53fcab1c')
res.send('Respond to DAST ping')
})
```
### Scanner profile
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/222767) in GitLab 13.4.
> - [Added](https://gitlab.com/gitlab-org/gitlab/-/issues/225804) in GitLab 13.5: scan mode, AJAX spider, debug messages.
A scanner profile defines the scanner settings used to run an on-demand scan:
- **Profile name:** A name you give the scanner profile. For example, "Spider_15".
- **Scan mode:** A passive scan monitors all HTTP messages (requests and responses) sent to the target. An active scan attacks the target to find potential vulnerabilities.
- **Spider timeout:** The maximum number of minutes allowed for the spider to traverse the site.
- **Target timeout:** The maximum number of seconds DAST waits for the site to be available before
starting the scan.
- **AJAX spider:** Run the AJAX spider, in addition to the traditional spider, to crawl the target site.
- **Debug messages:** Include debug messages in the DAST console output.
#### Create a scanner profile
To create a scanner profile:
1. From your project's home page, go to **Security & Compliance > Configuration**.
1. In the **DAST Profiles** row select **Manage**.
1. Select **New > Scanner Profile**.

## Reports
The DAST tool outputs a report file in JSON format by default. However, this tool can also generate reports in
Markdown, HTML, and XML. For more information, see the [schema for DAST reports](https://gitlab.com/gitlab-org/security-products/security-report-schemas/-/blob/master/dist/dast-report-format.json).
### List of URLs scanned
When DAST completes scanning, the merge request page states the number of URLs scanned.
Click **View details** to view the web console output which includes the list of scanned URLs.
![DAST Widget](img/dast_urls_scanned_v12_10.png)
### JSON
WARNING:
The JSON report artifacts are not a public API of DAST and their format is expected to change in the future.
The DAST tool always emits a JSON report file called `gl-dast-report.json` and
sample reports can be found in the
[DAST repository](https://gitlab.com/gitlab-org/security-products/dast/-/tree/master/test/end-to-end/expect).
There are two formats of data in the JSON report that are used side by side:
- The proprietary ZAP format, which is planned to be deprecated.
- A common format that is planned to the default in the future.
### Other formats
Reports can also be generated in Markdown, HTML, and XML. These can be published as artifacts using the following configuration:
```yaml
include:
template: DAST.gitlab-ci.yml
dast:
variables:
DAST_HTML_REPORT: report.html
DAST_MARKDOWN_REPORT: report.md
DAST_XML_REPORT: report.xml
artifacts:
paths:
- $DAST_HTML_REPORT
- $DAST_MARKDOWN_REPORT
- $DAST_XML_REPORT
- gl-dast-report.json
```
## Optimizing DAST
By default, DAST downloads all artifacts defined by previous jobs in the pipeline. If
your DAST job does not rely on `environment_url.txt` to define the URL under test or any other files created
in previous jobs, we recommend you don't download artifacts. To avoid downloading
artifacts, add the following to your `gitlab-ci.yml` file:
```json
dast:
dependencies: []
```
