Estado: ModificadaAlta (8.8)—

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-842 3.13B05 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of HNAP GetCAPTCHAsetting requests. The issue results from the lack of proper handling of sessions. An attacker can leverage this vulnerability to execute arbitrary code in the context of the device. Was ZDI-CAN-10083.
