Description
TVU Networks Receiver/Transceiver devices running firmware before version 7.9 contain a missing authentication vulnerability that allows remote unauthenticated attackers to read sensitive device information and modify device configuration via unprotected REST API endpoints on port 8288. Attackers can send unauthenticated GET requests to disclose network configuration, firmware details, and cloud service information, or issue POST requests to endpoints such as /Setting3/API/API/v1/LocalNetwork/DNS to alter DNS settings and enable man-in-the-middle attacks on outbound connections to TVU cloud infrastructure.
