Authenticated command injection via OAuth code concatenation

Published Nov 3, 2023 · Updated Sep 6, 2024

OS command injection in ASUS RT-AX55 firmware 3.0.0.4.386.51598 allows remote authenticated users to execute commands through its web interface. The sbin/rc code reads oauth_google_auth_code from NVRAM and concatenates it into a system command without filtering shell metacharacters. A valid management session is required; injected commands can alter router data or configuration, interrupt services, or compromise the appliance.
