Technical summary

The SmartCenter browserseturl command in the Telefunken TE24553B45V2DZ Smart TV running on the Vestel MB181 / Voltron181 / TiVo OS platform has an improper restriction of URL schemes and destinations. This 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. The issue affects firmware version V2.78.0.0 and is fixed in firmware version V2.85.2.0.

Defensive priority

Organizations using the Telefunken TE24553B45V2DZ Smart TV with firmware version V2.78.0.0 should update to V2.85.2.0 to mitigate this vulnerability. Network administrators should restrict access to the SmartCenter browserseturl command and monitor for unusual activity.

Recommended defensive actions

• Update firmware to V2.85.2.0
• Restrict access to the SmartCenter browserseturl command
• Monitor for unusual activity
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
