CVE-2022-28387Public exploit

Stored-data disclosure via password-retrieval IOCTL

Published Jun 8, 2022 · Updated Aug 3, 2024

Password disclosure in Verbatim fingerprint-secured drives through 2022-03-31 allows physically proximate attackers to read stored data. The INIC-3637EN bridge returns the current password and disk key material to a device-specific IOCTL request, while a hard-coded AES key in the client and firmware exposes the response. Physical possession of an affected drive is required; the recovered password unlocks the encrypted volume without a registered fingerprint or prior password.
