oBike relies on Hangzhou Luoping Smart Locker to lock bicycles, which allows attackers to bypass the locking mechanism by using Bluetooth Low Energy (BLE) to replay ciphertext based on a predictable nonce used in the locking protocol.
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).
