Going back to this original report of the vulnerability. Has it been established with certainty that the attacker would first need MITM capability to exploit the vulnerability? I’m asking this because MITM capability is not something that just any attacker can do. Also if this is true then it can be argued that the severity of this vulnerabilty has be greatly exaggerated. -Kimmo
