Vulnerability from variot
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R7800. Authentication is not required to exploit this vulnerability. The specific flaw exists within the apply_save.cgi endpoint. This issue results from the use of hard-coded encryption key. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. Was ZDI-CAN-12287. Zero Day Initiative To this vulnerability ZDI-CAN-12287 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state
