phpBB PJIRC Module 0.5 - 'irc.php' Local File Inclusion

                source: http://www.securityfocus.com/bid/28446/info

The PJIRC module for phpBB is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability using directory-traversal strings to view files and execute local scripts in the context of the webserver process. This may aid in further attacks.
