CGIForum is a commercial cgi script from Markus Triska which is designed to facilitate web-based threaded discussion forums.
|

The script improperly validates user-supplied input to the "thesection" parameter. If an attacker supplies a carefully-formed URL contaning '/../' sequences as argument to this parameter, the script will traverse the normal directory structure of the application in order to find the specified file. As a result, it is possible to remotely view arbitrary files on the host which are readable by user 'nobody'.
