CVE-2022-38788

Bluetooth key disclosure via crackable pairing handshake

Published Sep 15, 2022 · Updated Aug 3, 2024

Information disclosure in Nokia FastMile 5G Receiver 5G14-B 1.2104.00.0281 allows physically proximate attackers to recover Bluetooth keys. The ODU uses an outdated Bluetooth pairing exchange whose passively captured handshake permits offline derivation of the PIN and long-term key. The attacker must be within Bluetooth interception range during pairing; the disclosed material compromises link confidentiality without reported data modification or service interruption.
