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.
AnalysisAI
Server-Side Request Forgery in the Telefunken TE24553B45V2DZ Smart TV firmware V2.78.0.0 allows a network-adjacent unauthenticated attacker to abuse the SmartCenter browserseturl command, redirecting the device's embedded browser to loopback (127.0.0.1) and internal network destinations that are otherwise unreachable through normal browser navigation. The Vestel MB181 / Voltron181 / TiVo OS platform's SmartCenter component fails to restrict target URL schemes and destinations, enabling the TV to serve as an internal SSRF proxy against its own locally-running services. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must occupy the same local network segment (LAN or Wi-Fi) as the TV - internet-based exploitation is precluded by AV:A. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:L) scores 7.1, with the AV:A constraint being the single most significant risk-limiting factor - exploitation requires the attacker to share the same LAN or Wi-Fi segment as the TV, ruling out internet-scale opportunistic attacks. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The vendor-released patch is firmware version V2.85.2.0, which resolves the URL restriction bypass in the SmartCenter browserseturl command. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
