Vulnerability from variot
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R7450 1.2.0.62_1.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. The issue results from improper state tracking in the password recovery process. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-11365. NETGEAR R7450 A router contains a vulnerability related to the leakage of resources to the wrong area. Zero Day Initiative To this vulnerability ZDI-CAN-11365 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. NETGEAR R7450 is a router from Netgear. A hardware device that connects two or more networks and acts as a gateway between the networks
