Summary

KAYSUS KS-WR1200 routers with firmware 107 expose SSH and TELNET services on the LAN interface with hardcoded root credentials (root:12345678). The administrator cannot disable these services or change the hardcoded password, and changing the GUI password does not affect SSH/TELNET authentication.

Risk Assessment

Any LAN-adjacent attacker can trivially log in with root privileges, taking full control of the router. This can lead to traffic interception, configuration modification, and further network attacks.

Recommendation

Update the router firmware to a patched version or replace the device, and until then restrict LAN access and monitor for unusual SSH/TELNET connections.
