CVE-2025-32876

Estado: AnalizadaMedia (6.8)—

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.

La implementación BLE del reloj inteligente COROS no es compatible con las conexiones seguras LE y, en su lugar, aplica el emparejamiento heredado BLE. En el emparejamiento heredado BLE, la clave de corto plazo (STK) se puede adivinar fácilmente. Esto requiere conocer la clave temporal (TK), que, en el caso del COROS Pace 3, está configurada a 0 debido al método de emparejamiento Just Works. Por lo tanto, un atacante dentro del alcance de Bluetooth puede realizar ataques de rastreo, lo que permite interceptar la comunicación."
