The exploitation is known to be difficult. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in the Shenzhen HCC Technology MPOS M6 PLUS version 1V.31-N, specifically within the Bluetooth Handler component. This vulnerability allows for authentication bypass through capture-replay attacks, where legitimate Bluetooth commands can be intercepted and replayed to the terminal as new transactions. The lack of proper temporal validation mechanisms, such as nonces or timestamps, enables this replay attack. The vulnerability requires access to the local network and is considered to have high complexity, making exploitation difficult.
It is recommended that the manufacturer implement cryptographic nonces, timestamp validation, and other standard anti-replay mechanisms to protect against this type of vulnerability.
