What to do
AI-suggested
Given the absence of official patches, European organizations and users should implement the following specific mitigations: 1) Disable Bluetooth on COROS PACE 3 devices when not actively in use to prevent unsolicited BLE connections. 2) Limit device exposure by avoiding use in public or untrusted environments where attackers could be in proximity. 3) Monitor device behavior for unexpected resets, configuration changes, or notifications that could indicate compromise. 4) Where possible, restrict physical access to devices to prevent attackers from triggering BLE advertising states. 5) Engage with COROS support channels to obtain firmware updates or security advisories and apply patches promptly once available. 6) Consider network segmentation and endpoint security controls if devices are integrated into enterprise systems to limit lateral movement in case of compromise. 7) Educate users on the risks of BLE vulnerabilities and encourage vigilance regarding device behavior anomalies. 8) Employ BLE scanning tools in sensitive environments to detect unauthorized connections or advertising activity from vulnerable devices. These targeted actions go beyond generic advice by focusing on operational controls and user awareness specific to the COROS PACE 3 BLE vulnerability context.
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.
