A critical encryption vulnerability in Lenovo’s ThinkPad Manager Pro software exposes laptops running Windows 7, 8, and 8.1 could allow hackers access into a user’s computer by bypassing fingerprint recognition, the company confirmed last week in a security advisory.
“A vulnerability has been identified 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,” reads the statement.
Devices running Windows 10 were not affected because they use the fingerprint reader support from Microsoft.
To exploit the vulnerability, hackers had do to it in person as local access was required.
A patch for the Fingerprint Manager Pro application was released on Jan. 25. Users with vulnerable models are encouraged to download and install version 8.01.87.
