      "value": "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."

      "value": "Un televisor inteligente TCL que ejecuta una implementación vulnerable de UPnP/DLNA MediaRenderer se ve afectado por una condición remota, no autenticada de denegación de servicio (DoS). Al enviar una avalancha de solicitudes SOAP SetAVTransportURI malformadas o de tamaño excesivo al punto final de control UPnP, un atacante puede hacer que el dispositivo deje de responder. Esta denegación persiste mientras el ataque continúa y afecta a todas las formas de funcionamiento del televisor. El control manual del usuario e incluso los reinicios no restauran la funcionalidad a menos que la avalancha se detenga."
