In versions prior to 5.0.1 The exported activity `de.niklasmerz.cordova.biometric.BiometricActivity` can cause the app to crash. This vulnerability occurred because the activity didn't handle the case where it is requested with invalid or empty data which results in a crash. Any third party app can constantly call this activity with no permission. A 3rd party app/attacker using event listener can continually stop the app from working and make the victim unable to open it. 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 in plugin.xml to false. Please upgrade to version 5.0.1 as soon as possible." } ] }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 6.2, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-617: Reachable Assertion" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/security/advisories/GHSA-7vfx-hfvm-rhr8", "refsource": "CONFIRM", "url": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/security/advisories/GHSA-7vfx-hfvm-rhr8" }, { "name": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/commit/27434a240f97f69fd930088654590c8ba43569df", "refsource": "MISC", "url": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/commit/27434a240f97f69fd930088654590c8ba43569df" }, { "name": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/releases/tag/v5.0.1", "refsource": "MISC", "url": "https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/releases/tag/v5.0.1" } ] }, "source": { "advisory": "GHSA-7vfx-hfvm-rhr8", "discovery": "UNKNOWN" } }
