CVE-2025-32877 Details
Description
An issue was discovered on COROS PACE 3 devices through 3.0808.0. It identifies itself as a device without input or output capabilities, which results in the use of the Just Works pairing method. This method does not implement any authentication, which therefore allows machine-in-the-middle attacks. Furthermore, this lack of authentication allows attackers to interact with the device via BLE without requiring prior authorization.
A vulnerability exists in the COROS PACE 3 smartwatch, all versions through 3.0808.0, due to the device's identification as having no input or output capabilities. This designation forces the use of the 'Just Works' pairing method, which lacks authentication, making the device susceptible to machine-in-the-middle attacks. Exploitation of this vulnerability allows unauthorized interaction with the device via Bluetooth Low Energy (BLE) without prior authorization.
COROS has been notified of the vulnerability and plans to release a fix by the end of 2025.
