{"id":"CVE-2020-10135","details":"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.","modified":"2026-03-15T22:30:09.022002Z","published":"2020-05-19T16:15:11.073Z","related":["SUSE-SU-2020:2102-1","SUSE-SU-2020:2105-1","SUSE-SU-2020:2119-1","SUSE-SU-2020:2122-1","SUSE-SU-2020:2134-1","SUSE-SU-2020:2152-1","SUSE-SU-2020:2487-1","SUSE-SU-2020:2541-1","SUSE-SU-2020:2575-1","SUSE-SU-2020:2605-1","SUSE-SU-2020:2610-1","SUSE-SU-2020:2623-1","SUSE-SU-2024:2360-1","SUSE-SU-2024:2365-1","SUSE-SU-2024:2561-1","openSUSE-SU-2020:1153-1","openSUSE-SU-2020:1236-1","openSUSE-SU-2021:0242-1","openSUSE-SU-2024:10728-1","openSUSE-SU-2024:13704-1"],"references":[{"type":"ADVISORY","url":"https://francozappa.github.io/about-bias/"},{"type":"ADVISORY","url":"https://kb.cert.org/vuls/id/647177/"},{"type":"ADVISORY","url":"https://www.bluetooth.com/learn-about-bluetooth/bluetooth-technology/bluetooth-security/bias-vulnerability/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00047.html"},{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/157922/Bluetooth-Impersonation-Attack-BIAS-Proof-Of-Concept.html"},{"type":"EVIDENCE","url":"http://seclists.org/fulldisclosure/2020/Jun/5"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"5.2"}]},{"events":[{"introduced":"0"},{"last_affected":"5.2"}]},{"events":[{"introduced":"0"},{"last_affected":"15.1"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-10135.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
