X7 Chat help/index.php help_file Parameter Local File Inclusion

medium Nessus Plugin ID 21312

Language:

Synopsis

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 privileges of the web server user id.

Solution

Upgrade to X7 Chat version 2.0.3 or later.
