CVE-2023-35722

Root code execution via unvalidated UPnP port mapping

Published May 3, 2024 · Updated Aug 2, 2024

OS command injection in NETGEAR RAX30 firmware before 1.0.11.96_2_HOTFIX allows remote attackers to execute code through UPnP. The UPnP port-mapping handler passes a user-supplied string to a system call without validating command metacharacters. Reachability requires the same Wi-Fi network or an Ethernet connection, and successful injection runs arbitrary code as root without authentication.
