Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 has an authentication bypass vulnerability in its remote-control MQTT broker on TCP port 36669. The broker uses publicly documented default credentials and a weak 4-digit pairing PIN without rate limiting or lockout, allowing brute force attacks in about five seconds. Some actions require no pairing, enabling a LAN-adjacent attacker to inject key events, change volume, switch inputs, enumerate inputs, launch apps, and monitor pairing activity. This poses a significant risk especially in hotel environments with untrusted LAN access.
