 Vulnerability

Description
A vulnerability has been discovered in the advertising component for Joomla, which can be exploited by malicious people to disclose potentially sensitive information.

Input passed to the '"task" parameter in index.php (when "option" is set to "com_aardvertiser") is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks.

The vulnerability is confirmed in Joomla 1.5 com_aardvertiser V2.0.
