Description

Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key.

Techniques & Countermeasures

  • CWE-757•Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

    A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.

  • CWE-290•Authentication Bypass by Spoofing

    This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
