CVE-2020-15802
Devices supporting Bluetooth before 5.1 may allow man-in-the-middle attacks, aka BLURtooth.
Does this matter?
Lower severity and a low EPSS score (7.08%). Track it; it rarely justifies an emergency change on its own.
Description
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.
