Biometric authentication bypass via unchecked result
Published Sep 10, 2021 · Updated Aug 3, 2024
Authentication bypass in Ionic Identity Vault before 5 allows local root attackers on Android devices to bypass biometric authentication. The Android IonicNativeAuth.onBiometricActivityResult handler accepts a manipulated authentication result, and the Android Keystore entry does not require user authentication, allowing root code to force a successful unlock. Root code execution on the device is required; successful exploitation grants access to vault-protected identity and session data without a valid biometric.
