Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper implementation of the authentication algorithm. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-9470.
