GHSA-MG6C-H9C4-RCC2

Vulnerability from github – Published: 2022-05-24 22:28 – Updated: 2024-04-04 03:10

Details

Legacy pairing and secure-connections pairing authentication in BluetoothÂ® 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.

Severity ?

5.4 (Medium)

Vulnerability from cvelistv5 – Published: 2020-05-19 15:50 – Updated: 2024-09-17 02:57

Title

Bluetooth devices supporting BR/EDR v5.2 and earlier are vulnerable to impersonation attacks

Summary

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.

Severity ?
