No we did right with CCMP.  BUT:

Depends on the key establishment method.

I have published a paper on attacking PSK mode, and my method has been 
incorporated into the wireless attack tools.

Improper configuration of acceptable certificate trust can compromise any 
of the TLS-based EAP methods (TLS, PEAP, TTLS).  With TTLS being perhaps 
the easiest to attack in this case.

There's no limit to what can be accomplished if it doesn't matter who gets 
the credit
