# X-Powered-By header exposes version information
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
The target website returns the `X-Powered-By` header 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
|
||
|
|
|
||
|
|
We recommend that the version information be removed from the `X-Powered-By` header.
|
||
|
|
|
||
|
|
PHP:
|
||
|
|
For PHP based web sites, set the `expose_php` option to `off` in the `php.ini` configuration file.
|
||
|
|
|
||
|
|
For all other server types, please consult your product's documentation on how to redact the version
|
||
|
|
information from the `X-Powered-By` header.
