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.
