DescriptionNVD

Executive ViewAI

Why It Matters

A logic error in the BiometricService component could allow attackers with local device access to bypass fingerprint unlock controls, enabling unauthorized access to sensitive data and systems. This vulnerability affects any organization relying on biometric authentication for mobile or endpoint device security, potentially compromising user accounts and protected information.

Business Impact: High

Compensating Controls

Disable fingerprint unlock feature in BiometricService settings; enforce multi-factor authentication (MFA) requiring PIN or password in addition to biometrics; implement device-level access controls limiting local unlock attempts; segment networks to restrict lateral movement from compromised devices; monitor and log BiometricService authentication events for anomalies; consider hardware-based authentication tokens as temporary alternative to biometric unlock.

Attack Technique

Authentication Bypass CRITICAL

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
