{"id":"GHSA-fffr-7x4x-f98q","aliases":["BIT-typo3-2022-36104","CVE-2022-36104"],"title":"TYPO3 CMS vulnerable to Denial of Service in Page Error Handling","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"> ### 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)","severity":"medium","score":5.9,"published":"2022-09-16T17:16:46.000Z","modified":"2023-12-06T01:02:29.715Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"typo3/cms-core","sources":[{"name":"OSV · GHSA-fffr-7x4x-f98q","url":"https://osv.dev/vulnerability/GHSA-fffr-7x4x-f98q"}],"ranges":[{"events":[{"introduced":"11.4.0"},{"fixed":"11.5.16"}],"type":"ECOSYSTEM"}],"versions":["v11.4.0","v11.5.0","v11.5.1","v11.5.10","v11.5.11","v11.5.12","v11.5.13","v11.5.14","v11.5.15","v11.5.2","v11.5.3","v11.5.4","v11.5.5","v11.5.6","v11.5.7","v11.5.8","v11.5.9"],"fixed":["11.5.16"]},{"ecosystem":"Packagist","name":"typo3/cms","sources":[{"name":"OSV · GHSA-fffr-7x4x-f98q","url":"https://osv.dev/vulnerability/GHSA-fffr-7x4x-f98q"}],"ranges":[{"events":[{"introduced":"11.4.0"},{"fixed":"11.5.16"}],"type":"ECOSYSTEM"}],"versions":["v11.4.0","v11.5.0","v11.5.1","v11.5.10","v11.5.11","v11.5.12","v11.5.13","v11.5.14","v11.5.15","v11.5.2","v11.5.3","v11.5.4","v11.5.5","v11.5.6","v11.5.7","v11.5.8","v11.5.9"],"fixed":["11.5.16"]}],"sourceAffected":[],"references":["https://github.com/TYPO3/typo3/security/advisories/GHSA-fffr-7x4x-f98q","https://nvd.nist.gov/vuln/detail/CVE-2022-36104","https://github.com/TYPO3/typo3/commit/179dd7cd78947081d573fee2050e197faa556f13","https://github.com/TYPO3/typo3/commit/fc51ccbf2bb8a8c959aa74cbceca124971e6e7fd","https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/CVE-2022-36104.yaml","https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/CVE-2022-36104.yaml","https://github.com/TYPO3/typo3","https://typo3.org/security/advisory/typo3-core-sa-2022-006"],"sources":[{"name":"OSV","id":"GHSA-fffr-7x4x-f98q","modified":"2023-12-06T01:02:29.715867Z","url":"https://osv.dev/vulnerability/GHSA-fffr-7x4x-f98q"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-29T00:35:31.531Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
