Improper URL Scheme Restriction in Telefunken Smart TV

Publication date: 2026-08-07

Last updated on: 2026-08-07

Assigner: 5431be70-064b-4f6a-be51-69eacabef109

Description
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.

Executive Summary

This vulnerability involves an improper restriction in the SmartCenter browserseturl command on the Telefunken TE24553B45V2DZ Smart TV running Vestel MB181 / Voltron181 / TiVo OS. It allows attackers on the same local network to manipulate the TV's embedded browser into sending requests to unintended internal destinations, including loopback addresses like 127.0.0.1. The issue was present in firmware version V2.78.0.0 and fixed in V2.85.2.0.

Impact Analysis

An attacker could exploit this to send requests to internal services on your Smart TV that are normally inaccessible. This might allow them to interact with sensitive services, potentially stealing data or executing unauthorized actions. The impact depends on what internal services are running and their security.

Compliance Impact

The vulnerability allows local network attackers to bypass intended browser restrictions and access internal services via loopback addresses. This could lead to unauthorized data exfiltration or manipulation, potentially violating GDPR's data protection requirements and HIPAA's safeguards for protected health information if exploited in healthcare environments.

Mitigation Strategies

Update the TE24553B45V2DZ Smart TV firmware to version V2.85.2.0 or later to address the vulnerability.
