Lenovo’s Fingerprint Scanner Can Be Bypassed via a Hardcoded Password[bleepingcomputer]
by CIRT Team
Lenovo has issued security updates for a fingerprint scanner app it shipped with ThinkPad, ThinkCentre, and ThinkStation machines.
Fingerprint Manager Pro is an application developed by Lenovo that allows users to log into Windows machines and online websites by scanning one of their fingerprints using the fingerprint scanner embedded in selected Lenovo products.
“A vulnerability has been identified in Lenovo Fingerprint Manager Pro,” said Lenovo in a security advisory published last week.
“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.
What this means is that an attacker could take advantage of the hardcoded password to bypass fingerprint authentication, and even decrypt existing Windows logon credentials and fingerprint data.
Update made available last week
Lenovo Fingerprint Manager Pro for Windows 7, 8, and 8.1 versions are affected. Lenovo has published version 8.01.87 that fixes the said problem.
