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.
