{"id":"CVE-2022-36105","aliases":["BIT-typo3-2022-36105","GHSA-m392-235j-9r7r"],"url":"https://o3.security/vulnerability/CVE-2022-36105","summary":"User Enumeration via Response Timing in TYPO3","details":"> ### Meta\n> * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:F/RL:O/RC:C` (4.9)\n\n### Problem\nIt has been discovered that observing response time during user authentication (backend and frontend) can be used to distinguish between existing and non-existing user accounts.\n\nExtension authors of 3rd party TYPO3 extensions providing a custom authentication service should check if the extension is affected by the described problem. Affected extensions must implement new `MimicServiceInterface::mimicAuthUser`, which simulates corresponding times regular processing would usually take.\n\n### Solution\nUpdate to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix the problem described above.\n\n### Credits\nThanks to Vautia who reported this issue and to TYPO3 core & security team members Oliver Hader who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2022-007](https://typo3.org/security/advisory/typo3-core-sa-2022-007)\n* [Vulnerability Report on huntr.dev](https://huntr.dev/bounties/7d519735-2877-4fad-bd77-accde3e290a7/) (embargoed +30 days)","published":"2022-09-13T17:40:13Z","modified":"2026-08-27T03:30:25.893132241Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"7.6.58"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"8.7.48"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"9.5.37"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"10.4.32"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"11.5.16"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"10.4.32"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"11.5.16"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/f8b83ce15d4ea275a5a5e564e5d324242f7937b6","label":"TYPO3/typo3@f8b83ce"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36105.json"},{"type":"ADVISORY","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-m392-235j-9r7r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36105"},{"type":"ADVISORY","url":"https://typo3.org/security/advisory/typo3-core-sa-2022-007"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/f8b83ce15d4ea275a5a5e564e5d324242f7937b6"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/f0fc9c4cd7c38207c30dd158de53ee5d9d6f41a2"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/CVE-2022-36105.yaml"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/CVE-2022-36105.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:30:25.893132241Z"}}
