Summary
Sciener locks' firmware update mechanism do not authenticate or validate firmware updates if passed to the lock through the Bluetooth Low Energy service. A challenge request can be sent to the lock with a command to prepare for an update, rather than an unlock request, allowing an attacker to compromise the device.
