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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
