Fingerprint Manager Pro is a utility for Microsoft Windows 7, 8 and 8.1 operating systems that allows users to log into their fingerprint-enabled Lenovo PCs using their fingers. The software could also be configured to store website credentials and authenticate site via fingerprint.
In addition to fingerprint data, the software also stores users sensitive information like their Windows login credentials—all of which are encrypted using a weak cryptography algorithm.
According to the company, Fingerprint Manager Pro version 8.01.86 and earlier contains a hard-coded password vulnerability, identified as CVE-2017-3762, that made the software accessible to all users with local non-administrative access.
"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," the company said in its advisory, giving brief about the vulnerability.

The popular Chinese computer manufacturer strongly recommends its ThinkPad customers to update their devices to Fingerprint Manager Pro version 8.01.87 or later to address the issue. You can also head on to the company's official website to do so.
Since Microsoft added native fingerprint reader support with Windows 10 operating system, thus eliminating the need for the Fingerprint Manager Pro software, Lenovo laptops running Windows 10 are not impacted by the vulnerability.
