CRITICAL 9.8

DescriptionCVE.org

An issue was discovered on COROS PACE 3 devices through 3.0808.0. It implements a function to connect the watch to a WLAN. This function is mainly for downloading firmware files. Before downloading firmware files, the watch requests some information about the firmware via HTTPS from the back-end API. However, the X.509 server certificate within the TLS handshake is not validated by the device. This allows an attacker within an active machine-in-the-middle position, using a TLS proxy and a self-signed certificate, to eavesdrop and manipulate the HTTPS communication. This could be abused, for example, for stealing the API access token of the assigned user account.

Executive ViewAI

Why It Matters

COROS PACE 3 smartwatches contain a critical vulnerability that allows attackers on the same network to intercept and manipulate firmware update communications, potentially stealing user account credentials and API tokens. This affects any organization whose employees use these devices and could expose corporate data and user accounts to unauthorized access.

Business Impact: Severe

Compensating Controls

Disable WLAN firmware update functionality on all COROS PACE 3 devices; isolate smartwatch traffic on a separate network segment with restricted outbound HTTPS access; implement enhanced monitoring for suspicious API token usage and account access patterns; require users to update credentials if devices accessed corporate networks; consider blocking COROS API endpoints at the firewall until vendor provides patch.
