Title: PHP Nuke AddOn Arbitrary File Disclosure Vulnerability

Severity: MODERATE

Description:

PHP Nuke AddOn is a set of modules that can add functionality to the popular PHP-Nuke website creation/maintenance tool.

An issue exists with PHPNuke AddOn which allows local attackers to break out of webroot and display arbitrary files.

When PHPNuke AddOn theme files attempt to check the content of a block, it will execute any file it finds. If a user creates a block which specifies an arbitrary file on the host then PHPNuke AddOn will attempt to open it. The user would have to create this script in wwwroot.

This issue may be exploitable remotely if the attacker has a way to upload files to the host, via anonymous ftp or some other avenue.
