CVE-2021-34865

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of multiple NETGEAR 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 incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-13313.

Esta vulnerabilidad permite a atacantes adyacentes a la red omitir la autenticación en las instalaciones afectadas de varios routers NETGEAR. No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta en el servicio mini_httpd, que escucha en el puerto TCP 80 por defecto. El problema es debido a una lógica incorrecta de coincidencia de cadenas cuando es accedida a páginas protegidas. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto de root. Fue ZDI-CAN-13313
