      "value": "An improper restriction of URL schemes and destinations in the SmartCenter browserseturl command in the Telefunken TE24553B45V2DZ Smart TV running on the Vestel MB181 / Voltron181 / TiVo OS platform allows an attacker with access to the same local network to cause the embedded browser to issue requests to unintended loopback/internal destinations, including 127.0.0.1 addresses. In demonstrated scenarios, requests initiated through the SmartCenter browserseturl mechanism could reach an internal service and receive a successful response, although the same destination was not reachable through normal browser navigation. The issue affects firmware version V2.78.0.0 and is fixed in firmware version V2.85.2.0."

En escenarios demostrados, las solicitudes iniciadas a través del mecanismo SmartCenter browserseturl podrían alcanzar un servicio interno y recibir una respuesta exitosa, aunque el mismo destino no era accesible a través de la navegación normal del navegador.
