Lenovo’s Fingerprint Scanner Has a Hardcoded Password – Install Fix ASAP
Lenovo Fingerprint Scanner can be bypassed using a hardcoded password, the company has warned. An attacker with local, non-admin access can potentially use a Local Privilege Escalation vulnerability (tracked as CVE-2017-3762) to bypass fingerprint authentication and get access to sensitive data, including Windows login information.
In a security advisory, the company said that it is delivering updates for the fingerprint scanner app that is shipped with ThinkPad, ThinkCentre, and ThinkStation series. "A vulnerability has been identified in Lenovo Fingerprint Manager Pro," Lenovo said, adding that sensitive data is accessible to all users with local 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."
