Cerberus Helpdesk contains a flaw that allows a remote cross site scripting attack. The flaw exists because the application does not validate the 'sid' and 'id' variables upon submission to the 'clients.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
