CVE-2020-29440: Tesla Model X Firmware

Medium severity, CVSS 4.6. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
