"According to its banner, the version of Kayako SupportSuite installed
on the remote host is earlier than 3.60.04.  Such versions are
affected by a persistent cross-site scripting vulnerability. 
Specifically, the installed version fails to sanitize input passed to
the subject field while creating a new support ticket.  An attacker
may be able to exploit this vulnerability by creating a new support
ticket with a specially crafted subject field, and inject arbitrary
HTML or script code into a user's browser which would get executed
every time the support ticket is viewed.");
