Tcl: Security Vulnerabilities
TCL 65C655 Smart TV, running firmware version V8-R75PT01-LF1V269.001116 (Android TV, Kernel 5.4.242+), is vulnerable to a blind, unauthenticated Server-Side Request Forgery (SSRF) vulnerability via the UPnP MediaRenderer service (AVTransport:1). The device accepts unauthenticated SetAVTransportURI SOAP requests over TCP/16398 and attempts to retrieve externally referenced URIs, including attacker-controlled payloads. The blind SSRF allows for sending requests on behalf of the TV, which can be leveraged to probe for other internal or external services accessible by the device (e.g., 127.0.0.1:16XXX, LAN services, or internet targets), potentially enabling additional exploit chains.

A TCL Smart TV running a vulnerable UPnP/DLNA MediaRenderer implementation is affected by a remote, unauthenticated Denial of Service (DoS) condition. By sending a flood of malformed or oversized SetAVTransportURI SOAP requests to the UPnP control endpoint, an attacker can cause the device to become unresponsive. This denial persists as long as the attack continues and affects all forms of TV operation. Manual user control and even reboots do not restore functionality unless the flood stops.
