Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.
