The remote host runs phpCMS, a content management system

This version is vulnerable to cross-site scripting due to a lack of 
sanitization of user-supplied data in parser.php script.
Successful exploitation of this issue may allow an attacker to execute 
malicious script code on a vulnerable server. 

Solution: Upgrade to version 1.2.1pl1 or newer
