CVSS v3.1

Official Description

An issue was discovered on COROS PACE 3 devices through 3.0808.0. It starts advertising if no device is connected via Bluetooth. This allows an attacker to connect with the device via BLE if no other device is connected. While connected, none of the BLE services and characteristics of the device require any authentication or security level. Therefore, any characteristic, depending on their mode of operation (read/write/notify), can be used by the connected attacker. This allows, for example, configuring the device, sending notifications, resetting the device to factory settings, or installing software.

Technical Analysis

CVE-2025-32879 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
