This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DAP-1330 1.10B01 BETA Wi-Fi range extenders. 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 handling of cookies. An attacker can leverage this vulnerability to execute arbitrary code on the router. Was ZDI-CAN-9554.

Weakness
