Beginning with GitLab 13.0, Docker privileged mode is necessary only if you've [enabled Docker-in-Docker for Dependency Scanning](#enabling-docker-in-docker).
GitLab relies on [`rules`](../../../ci/yaml/README.md#rules) to start relevant analyzers depending on the languages detected in the repository.
The current detection logic limits the maximum search depth to two levels. For example, the `gemnasium-dependency_scanning` job is enabled if a repository contains either a `Gemfile`or `api/Gemfile` file, but not if the only supported dependency file is `api/client/Gemfile`.
The following languages and dependency managers are supported:
The [Security Scanner Integration](../../../development/integrations/secure.md) documentation explains how to integrate other security scanners into GitLab.
| `SECURE_ANALYZERS_PREFIX` | Override the name of the Docker registry providing the official default images (proxy). Read more about [customizing analyzers](analyzers.md). |
| `DS_EXCLUDED_PATHS` | Exclude vulnerabilities from output based on the paths. A comma-separated list of patterns. Patterns can be globs, or file or folder paths (for example, `doc,spec`). Parent directories also match patterns. Default: `"spec, test, tests, tmp"` |
| `SECURE_LOG_LEVEL` | Set the minimum logging level. Messages of this logging level or higher are output. From highest to lowest severity, the logging levels are: `fatal`, `error`, `warn`, `info`, `debug`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/10880) in GitLab 13.1. Default: `info` |
The following variables configure the Docker-in-Docker orchestrator, and therefore are only used when the Docker-in-Docker mode is [enabled](#enabling-docker-in-docker).
| `DS_ANALYZER_IMAGES` | | Comma-separated list of custom images. The official default images are still enabled. Read more about [customizing analyzers](analyzers.md). |
| `DS_ANALYZER_IMAGE_TAG` | | Override the Docker tag of the official default images. Read more about [customizing analyzers](analyzers.md). |
| `DS_PULL_ANALYZER_IMAGES` | | Pull the images from the Docker registry (set to `0` to disable). |
| `DS_DOCKER_CLIENT_NEGOTIATION_TIMEOUT` | 2m | Time limit for Docker client negotiation. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, or `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
| `DS_PULL_ANALYZER_IMAGE_TIMEOUT` | 5m | Time limit when pulling an analyzer's image. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, or `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
| `DS_RUN_ANALYZER_TIMEOUT` | 20m | Time limit when running an analyzer. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, or `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
#### Configuring specific analyzers used by Dependency Scanning
The following variables are used for configuring specific analyzers (used for a specific language/framework).
| `PIP_EXTRA_INDEX_URL` | `gemnasium-python` | | Array of [extra URLs](https://pip.pypa.io/en/stable/reference/pip_install/#cmdoption-extra-index-url) of package indexes to use in addition to `PIP_INDEX_URL`. Comma-separated. |
| `DS_PIP_VERSION` | `gemnasium-python` | | Force the install of a specific pip version (example: `"19.3"`), otherwise the pip installed in the Docker image is used. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12811) in GitLab 12.7) |
| `DS_PIP_DEPENDENCY_PATH` | `gemnasium-python` | | Path to load Python pip dependencies from. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12412) in GitLab 12.2) |
| `DS_PYTHON_VERSION` | `retire.js` | | Version of Python. If set to 2, dependencies are installed using Python 2.7 instead of Python 3.6. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12296) in GitLab 12.1)|
| `DS_JAVA_VERSION` | `gemnasium-maven` | `11` | Version of Java. Available versions: `8`, `11`, `13`, `14`. Maven and Gradle use the Java version specified by this value. |
| `MAVEN_CLI_OPTS` | `gemnasium-maven` | `"-DskipTests --batch-mode"` | List of command line arguments that are passed to `maven` by the analyzer. See an example for [using private repositories](../index.md#using-private-maven-repos). |
| `GRADLE_CLI_OPTS` | `gemnasium-maven` | | List of command line arguments that are passed to `gradle` by the analyzer. |
| `SBT_CLI_OPTS` | `gemnasium-maven` | | List of command-line arguments that the analyzer passes to `sbt`. |
| `BUNDLER_AUDIT_UPDATE_DISABLED` | `bundler-audit` | `"false"` | Disable automatic updates for the `bundler-audit` analyzer. Useful if you're running Dependency Scanning in an offline, air-gapped environment.|
| `BUNDLER_AUDIT_ADVISORY_DB_URL` | `bundler-audit` | `https://github.com/rubysec/ruby-advisory-db` | URL of the advisory database used by bundler-audit. |
| `BUNDLER_AUDIT_ADVISORY_DB_REF_NAME` | `bundler-audit` | `master` | Git ref for the advisory database specified by `BUNDLER_AUDIT_ADVISORY_DB_URL`. |
| `RETIREJS_JS_ADVISORY_DB` | `retire.js` | `https://raw.githubusercontent.com/RetireJS/retire.js/master/repository/jsrepository.json` | Path or URL to `retire.js` JS vulnerability data file. Note that if the URL hosting the data file uses a custom SSL certificate, for example in an offline installation, you can pass the certificate in the `ADDITIONAL_CA_CERT_BUNDLE` environment variable. |
| `RETIREJS_NODE_ADVISORY_DB` | `retire.js` | `https://raw.githubusercontent.com/RetireJS/retire.js/master/repository/npmrepository.json` | Path or URL to `retire.js` node vulnerability data file. Note that if the URL hosting the data file uses a custom SSL certificate, for example in an offline installation, you can pass the certificate in the `ADDITIONAL_CA_CERT_BUNDLE` environment variable. |
| `RETIREJS_ADVISORY_DB_INSECURE` | `retire.js` | `false` | Enable fetching remote JS and Node vulnerability data files (defined by the `RETIREJS_JS_ADVISORY_DB` and `RETIREJS_NODE_ADVISORY_DB` variables) from hosts using an insecure or self-signed SSL (TLS) certificate. |
1. Configure GitLab Runner with Docker-in-Docker in [privileged mode](https://docs.gitlab.com/runner/executors/docker.html#use-docker-in-docker-with-privileged-mode).
The Dependency Scanning tool emits a JSON report file. For more information, see the
[schema for this report](https://gitlab.com/gitlab-org/security-products/security-report-schemas/-/blob/master/dist/dependency-scanning-report-format.json).
"message": "Regular Expression Denial of Service in debug",
"description": "The debug module is vulnerable to regular expression denial of service when untrusted user input is passed into the `o` formatter. It takes around 50k characters to block for 2 seconds making this a low severity issue.",
"description": "Some XML DOM traversal and canonicalization APIs may be inconsistent in handling of comments within XML nodes. Incorrect use of these APIs by some SAML libraries results in incorrect parsing of the inner text of XML nodes such that any inner text after the comment is lost prior to cryptographically signing the SAML message. Text after the comment, therefore, has no impact on the signature on the SAML message.\r\n\r\nA remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow attackers to bypass primary authentication for the affected SAML service provider.",
- Docker Container Registry with locally available copies of Dependency Scanning [analyzer](https://gitlab.com/gitlab-org/security-products/analyzers) images.
- _Only if scanning Ruby projects_: Host an offline Git copy of the [advisory database](https://github.com/rubysec/ruby-advisory-db).
- _Only if scanning npm/yarn projects_: Host an offline copy of the [retire.js](https://github.com/RetireJS/retire.js/) [node](https://github.com/RetireJS/retire.js/blob/master/repository/npmrepository.json) and [js](https://github.com/RetireJS/retire.js/blob/master/repository/jsrepository.json) advisory databases.
NOTE: **Note:**
GitLab Runner has a [default `pull policy` of `always`](https://docs.gitlab.com/runner/executors/docker.html#using-the-always-pull-policy),
copy is available. GitLab Runner's [`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
[`docker export`](https://docs.docker.com/engine/reference/commandline/export/), and [`docker import`](https://docs.docker.com/engine/reference/commandline/import/).
