CVE-2020-10134Public exploit

Connection hijacking via pairing-method confusion

Published May 19, 2020 · Updated Sep 16, 2024

Pairing method confusion in Bluetooth Core 5.2 and earlier allows physically proximate attackers to hijack connections during pairing. Numeric Comparison and Passkey Entry reuse a six-digit value, while peers fail to authenticate that both sides selected the same association model. The attack requires two devices pairing within wireless range and a user who enters one peer's comparison number as the other's passkey; successful pairing lets the attacker intercept or modify traffic exposed by enabled profiles.
