In short

NETGEAR routers contain a vulnerability that allows attackers to run malicious commands remotely by exploiting how the router processes user input in web requests. An attacker can trick the router into executing arbitrary commands without needing to log in first.

Technical detail

A command injection vulnerability exists in the cgi-bin endpoint of affected NETGEAR routers where insufficient input validation on the path parameter allows unauthenticated remote attackers to inject shell metacharacters and execute arbitrary system commands with router privileges. The vulnerability requires only network access to the router's web interface.
