NETGEAR Multiple Routers httpd Missing Authentication for Critical Function Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of multiple NETGEAR routers.

The issue results from the lack of authentication prior to allowing access to system configuration information. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-13708.
