CVE-2024-31695

Physical authentication bypass via mishandled fingerprint enrollment

Published Nov 14, 2024 · Updated Dec 3, 2024

Incorrect authorization in Binance 2.85.4 allows physically proximate attackers to bypass fingerprint authentication via enrollment. The Android app fails to invalidate its fingerprint-lock protection or require account reauthentication after a new device fingerprint is enrolled. Physical possession and knowledge of the device lock-screen PIN are required; successful bypass exposes financial information and transaction functions.
