# AspNet Header(s) exposes version information
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The target website returns AspNet header(s) and version information of this website. By
|
||
|
|
exposing these values attackers may attempt to identify if the target software is vulnerable to known
|
||
|
|
vulnerabilities, or catalog known sites running particular versions to exploit in the future when a
|
||
|
|
vulnerability is identified in the particular version.
|
||
|
|
|
||
|
|
## Remediation
|
||
|
|
|
||
|
|
To remove the `X-AspNet-Version` header set `<httpRuntime enableVersionHeader="false" />` in the `<system.Web>`
|
||
|
|
section of the `Web.config` file.
