Description

Celular contribute.cgi or contribute.pl scripts contains a flaw that allows a remote attacker to traverse outside of the web path. The issue is due to the contribute.pl or contribute.cgi script not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the template variable. It's possible that multiple files can be read via the contribdir variable.
