DescriptionCVE.org

A lack of authentication and authorization mechanisms in the Bluetooth Low Energy (BLE) communication protocol of SRK Powertech Pvt Ltd Pebble Prism Ultra v2.9.2 allows attackers to reverse engineer the protocol and execute arbitrary commands on the device without establishing a connection. This is exploitable over Bluetooth Low Energy (BLE) proximity (Adjacent), requiring no physical contact with the device. Furthermore, the vulnerability is not limited to arbitrary commands but includes cleartext data interception and unauthenticated firmware hijacking via OTA services.

Executive ViewAI

Why It Matters

A critical vulnerability in Pebble Prism Ultra v2.9.2 devices allows attackers to remotely execute arbitrary commands without authentication, with active public exploits already available. Any organization deploying these devices faces immediate risk of unauthorized control, data breach, and potential physical security compromise.

Business Impact: Severe
Compensating Controls

Disable BLE connectivity on affected devices if operationally feasible; implement strict network segmentation isolating Pebble devices to dedicated, air-gapped networks with no access to critical systems; deploy continuous BLE traffic monitoring to detect anomalous command patterns; restrict physical proximity to devices through controlled access; maintain offline backups of critical configurations; contact vendor (SRK Powertech) immediately for emergency patching timeline and interim mitigation guidance.

Attack Technique

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
