We've discovered multiple persistent cross site scripting vulnerabilities
in the latest version of Kayako SupportSuite (3.60.04). Because of
improper input validation an attacker (authenticated staff member) can
inject javascript code into the body or even subject of a knowledge base
article which will execute in to context of the victim's browser when they
view the pages in question. THis makes it possible to steal cookies,
hijack sessions and more. The severity of this is augmented by the fact
that the subjects of newly published articles appear on the home page of
the portal making it easy to compromise a large number of users.
The vendor has been notified, but until they issue a patch administrators
can modify the relevant php themselves to do better input validation.
