CVSS v3.1
5.4
Medium
| Vector | AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
Bluetooth BR/EDR Core Specification versions prior to v5.2
Description
The issue concerns a flaw in the authentication procedure of the Bluetooth BR/EDR protocol, allowing an unauthenticated, adjacent attacker to impersonate a Bluetooth BR/EDR master or slave and pair with a previously paired remote device without knowing the link key. This could potentially compromise the confidentiality and integrity of protected information.
Recommendations
For Bluetooth BR/EDR Core Specification versions prior to v5.2, consider implementing additional authentication measures or restricting access to sensitive data until a patch or update is available. As a temporary workaround, restrict the use of legacy pairing and secure-connections pairing authentication to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Exploit
Authentication Bypass by Spoofing
Improper Authentication
