Descriptions

Tesla Model X vehicles before 2020-11-23 do not perform certificate validation during an attempt to pair a new key fob with the body control module (BCM). This allows an attacker (who is inside a vehicle, or is otherwise able to send data over the CAN bus) to start and drive the vehicle with a spoofed key fob.

Los vehículos Tesla Model X anterior al 23-11-2020 no realizan la comprobación del certificado durante un intento de emparejar un nuevo llavero con el módulo de control de carrocería (BCM). Esto permite a un atacante (que se encuentra dentro de un vehículo, o que puede enviar datos por medio del bus CAN) arrancar y conducir el vehículo con un llavero falso
