Description

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

Techniques & Countermeasures

  • CWE-310•Cryptographic Issues

    Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.

  • CWE-327•Use of a Broken or Risky Cryptographic Algorithm

    The product uses a broken or risky cryptographic algorithm or protocol.
