Description
UpSignOn for Windows before 7.19.0 contains an insecure credential storage vulnerability that allows local attackers to retrieve the biometric unlock key stored in the Windows PasswordVault API without triggering any authentication prompt. Attackers can access the stored biometric key from a standard local process within the same Windows session to decrypt the protected vault files and export the entire password manager contents in cleartext.
