Description
Rooxis RXR-12 Wi-Fi router contains an undocumented telnet backdoor daemon (/usr/bin/telnetd_startup) that, upon receipt of a precomputed AES-128-CBC magic packet using a firmware-wide static key and IV, enables telnet service with default credentials, providing remote root access. Firmware 20260813_c2169ea5 removes the UDP listener entirely, and users can update through their local web interface.
