Summary

Zero Motorcycles firmware versions 44 and prior allow an attacker to forcibly pair a device with the motorcycle via Bluetooth. Once paired, an attacker can use the over-the-air firmware update functionality to potentially upload malicious firmware. The motorcycle must be in Bluetooth pairing mode, and the attacker must be in proximity and understand the pairing process throughout the update.

Risk Assessment

This could lead to installation of malicious firmware on the motorcycle, posing safety and security risks to the vehicle and its user. However, it requires physical proximity and active pairing mode.

Recommendation

Update the motorcycle firmware to a version later than 44 if available, and limit exposure to Bluetooth pairing mode. Consider disabling pairing when not in use.

Original NVD description (English source)

Zero Motorcycles firmware versions 44 and prior enable an attacker to forcibly pair a device with the motorcycle via Bluetooth. Once paired, an attacker can utilize over-the-air firmware updating functionality to potentially upload malicious firmware to the motorcycle. The motorcycle must first be in Bluetooth pairing mode, and the attacker must be in proximity of the vehicle and understand the full pairing process, to be able to pair their device with the vehicle. The attacker's device must remain paired with and in proximity of the motorcycle for the entire duration of the firmware update.
