tag_summary = "The remote web server contains a PHP script that permits information
disclosure of local files.

Description :

The version of phpMyFAQ on the remote host contains a flaw that may lead
to an unauthorized information disclosure.  The problem is that user
input passed to the 'action' parameter is not properly verified before
being used to include files, which could allow an remote attacker to
view any accessible file on the system, resulting in a loss of
confidentiality.";

tag_solution = "Upgrade to phpMyFAQ 1.3.13 or newer.";
