CVE-2026-5768
The Frontier X2 device allows unauthenticated BLE read/write access to critical GATT characteristics without enforcing pairing authentication or authorization. This allows attackers within BLE range to perform unauthorized control of device functions, including starting/stopping activities, triggering vibrations, causing denial-of-service conditions, and fuzzing characteristic values to induce unexpected behavior.
Leer descripción completaMostrar menos
Additionally, the Frontier X mobile application lacks proper BLE device authentication, allowing attackers to impersonate a legitimate Frontier X2 device and connect to the application. By cloning BLE advertisements and exposing expected GATT characteristics, attackers can manipulate activity states and inject fabricated health telemetry such as breathing rate, heart rate, strain, and other health-related data into the mobile application.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

"value": "El dispositivo Frontier X2 permite acceso de lectura/escritura BLE no autenticado a características GATT críticas sin aplicar autenticación o autorización de emparejamiento. Esto permite a los atacantes dentro del alcance BLE realizar un control no autorizado de las funciones del dispositivo, incluyendo iniciar/detener actividades, activar vibraciones, causar condiciones de denegación de servicio y 'fuzzing' de valores de características para inducir un comportamiento inesperado. Además, la aplicación móvil Frontier X carece de una autenticación adecuada del dispositivo BLE, permitiendo a los atacantes suplantar un dispositivo Frontier X2 legítimo y conectarse a la aplicación. Al clonar anuncios BLE y exponer características GATT esperadas, los atacantes pueden manipular estados de actividad e inyectar telemetría de salud fabricada como frecuencia respiratoria, frecuencia cardíaca, esfuerzo y otros datos relacionados con la salud en la aplicación móvil."
