MEDIUM 6.8

DescriptionCVE.org

An issue was discovered on COROS PACE 3 devices through 3.0808.0. The BLE implementation of the COROS smartwatch does not support LE Secure Connections and instead enforces BLE Legacy Pairing. In BLE Legacy Pairing, the Short-Term Key (STK) can be easily guessed. This requires knowledge of the Temporary Key (TK), which, in the case of the COROS Pace 3, is set to 0 due to the Just Works pairing method. An attacker within Bluetooth range can therefore perform sniffing attacks, allowing eavesdropping on the communication.

Analysis

Technical ContextAI

An authentication bypass vulnerability allows attackers to circumvent login mechanisms and gain unauthorized access without valid credentials. This vulnerability is classified as Missing Authentication for Critical Function (CWE-306).

RemediationAI

Implement robust authentication mechanisms. Use multi-factor authentication. Review authentication logic for bypass conditions. Remove default credentials.
