The remote host is running PHP Code Snippet Library (PHP-CSL), a library
written in PHP.

The remote version of this software is vulnerable to a cross-site scripting
attack.

An attacker can exploit it by compromising the values of the parameter
cat_select in index.php.

This can be used to take advantage of the trust between a client and server 
allowing the malicious user to execute malicious JavaScript on 
the client's machine.

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