Authenticated command injection in router firmware
Published Dec 26, 2021 · Updated Aug 4, 2024
Command injection in NETGEAR Orbi router firmware before listed fixed versions allows remote authenticated users to execute commands via adjacent network access. The vendor advisory identifies post-authentication command injection in the affected firmware but does not publish the specific request handler, parameter, or unsafe command construction locus. Exploitation requires valid device authentication and adjacent-network reachability; successful execution can compromise confidentiality, integrity, and availability of the router.
