Descriptions

Tesla Model 3 Gateway Firmware Signature Validation Bypass Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. An attacker must first obtain the ability to execute privileged code on the Tesla infotainment system in order to exploit this vulnerability. The specific flaw exists within the handling of firmware updates. The issue results from improper error-handling during the update process. An attacker can leverage this vulnerability to execute code in the context of Tesla's Gateway ECU. Was ZDI-CAN-20734.

Vulnerabilidad de omisión de validación de firma de firmware de puerta de enlace Tesla Model 3. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en los vehículos Tesla Model 3 afectados. Un atacante primero debe obtener la capacidad de ejecutar código privilegiado en el sistema de información y entretenimiento de Tesla para poder explotar esta vulnerabilidad. La falla específica existe en el manejo de actualizaciones de firmware. El problema se debe a un manejo inadecuado de errores durante el proceso de actualización. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la ECU Gateway de Tesla. Era ZDI-CAN-20734.
