CVE-2019-17137

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR AC1200 R6220 Firmware version 1.1.0.86 Smart WiFi Router. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of path strings. By inserting a null byte into the path, the user can skip most authentication checks. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-8616.
