Unauthorized fingerprint enrollment via static TLS keys
Published Jan 27, 2024 · Updated Oct 18, 2024
Hard-coded key use in Synaptics Fingerprint Driver before 6.0.17.1103 allows physically proximate attackers to enroll fingerprints. The WBF driver derives pairing-data encryption keys from static host information, letting extracted keys decrypt TLS handshake data and impersonate the driver to send restricted sensor commands. Physical sensor access and driver reverse engineering are required; enrollment can support Windows identification when Enhanced Sign-in Security is disabled.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
