The Fingerprint Manager Pro software shipped with Lenovo’s ThinkPad system has several vulnerabilities. So updating to the latest version is strongly recommended.
Lenovo has published a security advisory Lenovo Fingerprint Manager Pro for Windows 7, 8, and 8.1 only (not 10) Insecure Credential Storage describing a vulnerability. CVE-2017-3762 describes a Local Privilege Escalation vulnerability in Lenovo Fingerprint Manager Pro. Sensitive data stored by Lenovo Fingerprint Manager Pro, including users’ Windows logon credentials and fingerprint data, is encrypted using a weak algorithm, contains a hard-coded password, and is accessible to all users with local non-administrative access to the system it is installed in.
Affected are systems with Windows 7 SP 1, Windows 8 and Windows 8.1, that uses Lenovo Fingerprint Manager Pro to allows users to log into their PCs or authenticate to configured websites using fingerprint recognition. Lenovo Fingerprint Manager Pro may be installed on the following systems:

Mitigation Strategy for Customers is to update Fingerprint Manager Pro to version 8.01.87 or later. Systems with Windows 10 are not affected, because Windows 10 systems use Microsoft’s built-in fingerprint reader support instead.
