The remote web server is hosting ZeroBoard, a web-based BBS application.

The remote version of this software is vulnerable to cross-site scripting 
and remote script injection due to a lack of sanitization of user-supplied 
data.

Successful exploitation of this issue may allow an attacker to execute 
malicious script code on a vulnerable server. 

Solution: Upgrade to the latest version
Risk factor : Medium";
