{"id":"CVE-2022-24857","aliases":["GHSA-3r7g-wrpr-j5g4","PYSEC-2022-192"],"url":"https://o3.security/vulnerability/CVE-2022-24857","summary":"Multi factor authentication bypass in django-mfa3","details":"### Impact\n\ndjango-mfa3 is a library that implements multi factor authentication for the django web framework. It achieves this by modifying the regular login view. Django however has a second login view for its admin area. This second login view was not modified, so the multi factor authentication can be bypassed.\n\nYou are affected if you have activated both django-mfa3 (< 0.5.0) and django.contrib.admin and have not taken any other measures to prevent users from accessing the admin login view.\n\n### Patches\n\nThe issue has been fixed in django-mfa3 0.5.0.\n\n### Workarounds\n\nIt is possible to work around the issue by overwriting the admin login route, e.g. by adding the following URL definition *before* the admin routes:\n\n    url('admin/login/', lambda request: redirect(settings.LOGIN_URL)\n\n### References\n\n- [django-mfa3 changelog](https://github.com/xi/django-mfa3/blob/main/CHANGES.md#050-2022-04-15)\n","published":"2022-04-15T18:50:11Z","modified":"2026-08-12T03:51:11.621465378Z","cvss":{"score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"django-mfa3","fixedVersion":"0.5.0"}],"fix":{"url":"https://github.com/xi/django-mfa3/commit/32f656e22df120b84bdf010e014bb19bd97971de","label":"xi/django-mfa3@32f656e"},"references":[{"type":"WEB","url":"https://github.com/xi/django-mfa3/blob/main/CHANGES.md#050-2022-04-15"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/24xxx/CVE-2022-24857.json"},{"type":"ADVISORY","url":"https://github.com/xi/django-mfa3/security/advisories/GHSA-3r7g-wrpr-j5g4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-24857"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20220609-0003/"},{"type":"FIX","url":"https://github.com/xi/django-mfa3/commit/32f656e22df120b84bdf010e014bb19bd97971de"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/django-mfa3/PYSEC-2022-192.yaml"},{"type":"PACKAGE","url":"https://github.com/xi/django-mfa3"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20220609-0003"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.621465378Z"}}
