PHP 5.3.x < 5.3.13 CGI Query String Code Execution

high Nessus Plugin ID 59056

Synopsis

The remote web server uses a version of PHP that is affected by a remote code execution vulnerability.

Description

According to its banner, the version of PHP installed on the remote host is 5.3.x earlier than 5.3.13 and, as such, is potentially affected by a remote code execution and information disclosure vulnerability.

The fix for CVE-2012-1823 does not completely correct the CGI query vulnerability. Disclosure of PHP source code and code execution via query parameters are still possible.

Note that this vulnerability is exploitable only when PHP is used in CGI-based configurations. Apache with 'mod_php' is not an exploitable configuration.

Solution

Upgrade to PHP version 5.3.13 or later. A 'mod_rewrite' workaround is available as well.
