Lenovo says that the flaw affects Lenovo machines running Windows 7, Windows 8 and Windows 8.1. "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," Lenovo writes in a new support document.
It should be noted that Lenovo PCs running Windows 10 are not affected by this exploit, as they rely on that operating system's own built-in fingerprint authentication system. The following Lenovo systems are affected by the Fingerprint Manager Pro security exploit:
- ThinkPad L560
- ThinkPad P40 Yoga, P50s
