{"id":"CVE-2022-36104","aliases":["BIT-typo3-2022-36104","GHSA-fffr-7x4x-f98q"],"url":"https://o3.security/vulnerability/CVE-2022-36104","summary":"Denial of Service via Page Error Handling in TYPO3/cms","details":"> ### Meta\n> * CVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:F/RL:O/RC:C` (5.5)\n\n### Problem\nRequesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content  to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded.\n\nThis vulnerability is the same as described in [TYPO3-CORE-SA-2021-005](https://typo3.org/security/advisory/typo3-core-sa-2021-005) ([CVE-2021-21359](https://nvd.nist.gov/vuln/detail/CVE-2021-21359)). A regression, introduced during TYPO3 v11 development, led to this situation.\n\n### Solution\nUpdate to TYPO3 version 11.5.16 that fixes the problem described above.\n\n### Credits\nThanks to Rik Willems who reported this issue and to TYPO3 core & security team member Oliver Hader who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2022-006](https://typo3.org/security/advisory/typo3-core-sa-2022-006)","published":"2022-09-13T17:20:19Z","modified":"2026-08-27T03:31:05.605079875Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"11.5.16"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"11.5.16"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/179dd7cd78947081d573fee2050e197faa556f13","label":"TYPO3/typo3@179dd7c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36104.json"},{"type":"ADVISORY","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-fffr-7x4x-f98q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36104"},{"type":"ADVISORY","url":"https://typo3.org/security/advisory/typo3-core-sa-2022-006"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/179dd7cd78947081d573fee2050e197faa556f13"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/fc51ccbf2bb8a8c959aa74cbceca124971e6e7fd"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/CVE-2022-36104.yaml"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/CVE-2022-36104.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:31:05.605079875Z"}}
