Description
Fire-Boltt BSW013 smartwatch firmware through V0.0.8 contains a missing authentication vulnerability that allows unpaired attackers to inject notifications by writing to the proprietary BLE command characteristic. Attackers within Bluetooth range can craft commands protected only by a CRC-16/ARC checksum to vibrate the watch and display spoofed alert text for phishing.
