X7 Chat help_file Parameter Local File Include Vulnerability

Vulnerability Assessment Summary
Tries to read a local file using X7 Chat

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP script that is affected by a
local file include issue.

Description :

The remote host is running X7 Chat, a web-based chat program written
in PHP.

The version of X7 Chat installed on the remote host fails to properly
sanitize input to the 'help_file' parameter of the 'help/index.php'
script before using it in a PHP 'include_once()' function. Provided
PHP's 'register_globals' setting is enabled, an unauthenticated
attacker may be able to exploit this issue to view arbitrary files or
to execute arbitrary PHP code on the remote host, subject to the
rights of the web server user id.
