Description
Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated access vulnerability in the DIAL (Discovery and Launch) service on TCP port 56789, which accepts control requests from any LAN-adjacent device without authentication, pairing, or user notification. Attackers can query running application states, enumerate installed applications via HTTP response codes, terminate active sessions with a DELETE request, and launch applications or bypass YouTube's Origin check by spoofing the Origin header to disclose viewing activity and subscriptions or disrupt device functionality.
