{"id":"CVE-2021-43849","state":"PUBLISHED","title":"DoS vulnerability","description":"cordova-plugin-fingerprint-aio is a plugin provides a single and simple interface for accessing fingerprint APIs on both Android 6+ and iOS. 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.","publishedAt":"2021-12-23T16:20:10.000Z","updatedAt":"2024-08-04T04:10:16.890Z","severity":{"score":6.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["NiklasMerz cordova-plugin-fingerprint-aio"],"affected":[{"vendor":"NiklasMerz","product":"cordova-plugin-fingerprint-aio","versions":[{"version":"< 5.0.1","status":"affected"}]}],"references":["https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/security/advisories/GHSA-7vfx-hfvm-rhr8","https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/commit/27434a240f97f69fd930088654590c8ba43569df","https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio/releases/tag/v5.0.1"],"weaknesses":["CWE-617"],"ingestedAt":"2026-10-29T19:49:07.642Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/43xxx/CVE-2021-43849.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-43849","state":"PUBLISHED","datePublished":"2021-12-23T16:20:10.000Z","dateUpdated":"2024-08-04T04:10:16.890Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-11-16T00:00:00.000Z"},"containers":{"cna":{"title":"DoS vulnerability","descriptions":[{"lang":"en","value":"cordova-plugin-fingerprint-aio is a plugin provides a single and simple interface for accessing fingerprint APIs on both Android 6+ and iOS.
