Descriptions

Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (without possession of the AuthValue used in the provisioning protocol) to determine the AuthValue via a brute-force attack (unless the AuthValue is sufficiently random and changed each time).

Un Mesh Provisioning en el perfil de Bluetooth Mesh versiones 1.0 y 1.0.1, puede permitir a un dispositivo cercano (sin la posesión del AuthValue usado en el protocolo de aprovisionamiento) determinar el AuthValue por medio de un ataque de fuerza bruta (a menos que el AuthValue sea lo suficientemente aleatorio y se cambie cada vez)
