ShowMojo MojoBox Digital Lockbox 1.4 is vulnerable to Authentication Bypass. The implementation of the lock opening mechanism via Bluetooth Low Energy (BLE) is vulnerable to replay attacks. A malicious user is able to intercept BLE requests and replicate them to open the lock at any time. Alternatively, an attacker with physical access to the device on which the Android app is installed, can obtain the latest BLE messages via the app logs and use them for opening the lock.
Weakness
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
