CVE-2019-9506 (GCVE-0-2019-9506)

Vulnerability from cvelistv5 – Published: 2019-08-14 16:27 – Updated: 2024-09-16 19:14

Title

Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation

Summary

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.

Severity

7.6 (High)


                        
                          CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
