Moderate severity GitHub Reviewed Published Dec 23, 2021 in NiklasMerz/cordova-plugin-fingerprint-aio • Updated Nov 2, 2023

Package

npm cordova-plugin-fingerprint-aio (npm)

Affected versions

< 5.0.1

Patched versions

5.0.1

Description

Summary:

Sending a specially crafted intent with an invalid/empty extras de.niklasmerz.cordova.biometric.BiometricActivity can cause the app to crash. sending the intent repeatedly can prevent the app using this plugin from working, resulting in a denial of service (DoS) condition.

Impact

A 3rd party app/remote attacker can exploit this vulnerability by sending a malicious intent to the target device, causing the app using this plugin from working to crash or become unresponsive, resulting in a denial of service (DoS) condition.

Mitigation

Version 5.0.1 of the cordova-plugin-fingerprint-aio doesn't export the activity anymore and is no longer vulnerable.

If you want to fix older versions change the attribute android:exported of this code snippet in plugin.xml to false:

<config-file target="AndroidManifest.xml" parent="application">
      <activity android:name="de.niklasmerz.cordova.biometric.BiometricActivity" android:theme="@style/TransparentTheme" android:exported="false"/>
</config-file>

Patches

Please upgrade to version 5.0.1 as soon as possible.

Please check out the release on GitHub.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
