We've discovered a persistent XSS vulnerability in Kayako Support Suite Version 3.04.10.  Although other similar XSS 
and SQL injection vectors such GET requests/URLs and other vulnerable POST fields have been previously published, we've 
found no reference to this particular one.  Current versions are not vulnerable, however this particular vector has not 
been previously disclosed.

In verion 3.04.10 (and probably others) an attacker (authenticated staff member) can inject code simply by creating a 
support ticket and including a javascript in the ticket notes.  The script will execute in the context of the browser 
of any staff member who views the ticket allowing the attacker to steal cookies, spoof web pages, etc.
