##########################################################

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.
