Descriptions

Devices supporting Bluetooth before 5.1 may allow man-in-the-middle attacks, aka BLURtooth. Cross Transport Key Derivation in Bluetooth Core Specification v4.2 and v5.0 may permit an unauthenticated user to establish a bonding with one transport, either LE or BR/EDR, and replace a bonding already established on the opposing transport, BR/EDR or LE, potentially overwriting an authenticated key with an unauthenticated key, or a key with greater entropy with one with less.

Los dispositivos compatibles con Bluetooth versiones anteriores a 5.1, pueden permitir ataques de tipo man-in-the-middle. Cross Transport Key Derivation en Bluetooth Core Specification versiones v4.2 y v5.0, puede permitir a un usuario no autenticado establecer una vinculación con un transporte, ya sea LE o BR/EDR, y reemplazar una vinculación ya establecida en el transporte opuesto, BR/EDR o LE, potencialmente sobrescribiendo una clave autenticada con una clave no autenticada, o una clave con mayor entropía con una con menos
