The remote host runs Faq-O-Matic, a CGI-based system that automates 
the process of maintaining a FAQ.

The remote version of this software is vulnerable to cross-site scripting 
attacks in the script 'fom.cgi'.

With a specially crafted URL, an attacker can cause arbitrary code 
execution resulting in a loss of integrity.

Solution: Upgrade to the latest version of this software
