CVE-2020-10135
Bluetooth devices supporting BR/EDR v5.2 and earlier are vulnerable to impersonation attacks
MEDIUM 5.4EPSS 2.4%
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.
