1. Description
 
The Symantec Messaging Gateway can encounter an issue of cross site request forgery (also known as one-click attack and is abbreviated as CSRF or XSRF), which is a type of malicious exploit of a website where unauthorized commands are transmitted from a user that the web application trusts. A CSRF attack attempts to exploit the trust that a specific website has in a user's browser. 
 
2. Proof of concept
 
The SMG did not protect the logout form with csrf token, therefore i can logout any user by sending this url https://YourIPHere/brightmail/logout.do
Here's an attack vector:

1) Set up a honeypot that detects SMG scans/attacks (somehow).
2) Once I get a probe, fire back a logout request.
3) Continue to logout the active user forever.

It's less damaging than a traditional "hack back" but is sure to irritate the local red team to no end. It's essentially a user DoS.
