The Misfortune Cookie Vulnerability

"Misfortune Cookie is a critical vulnerability that allows an intruder to remotely take over an Internet router and use it to attack home and business networks."

"The Misfortune Cookie vulnerability is due to an error within the HTTP cookie management mechanism present in the affected software, allowing an attacker to determine the ‘fortune’ of a request by manipulating cookies. Attackers can send specially crafted HTTP cookies that exploit the vulnerability to corrupt memory and alter the application and system state. This, in effect, can trick the attacked device to treat the current session with administrative privileges - to the misfortune of the device owner."
