CVE-2023-27356

Root code execution via logCtrl command injection

Published May 3, 2024 · Updated Aug 2, 2024

OS command injection in NETGEAR RAX30 firmware 1.0.9.90_3 allows network-adjacent attackers to execute arbitrary code as root. The logCtrl action passes an inadequately validated user-supplied string into a system call, enabling command execution in the router's root context. Access requires the WiFi password or an Ethernet connection, while the affected authentication path can be bypassed.
