X-Powered-By header exposes version information


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.


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.
