{"id":"BIT-typo3-2021-21359","details":"TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 9.5.25, 10.4.14, 11.1.1 requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as 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. This is fixed in versions 9.5.25, 10.4.14, 11.1.1.","aliases":["CVE-2021-21359","GHSA-4p9g-qgx9-397p"],"modified":"2024-03-06T11:25:28.861Z","published":"2024-03-06T11:10:59.597Z","database_specific":{"cpes":["cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/TYPO3.CMS/security/advisories/GHSA-4p9g-qgx9-397p"},{"type":"WEB","url":"https://packagist.org/packages/typo3/cms-core"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2021-005"}],"affected":[{"package":{"name":"typo3","ecosystem":"Bitnami","purl":"pkg:bitnami/typo3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.5.25"},{"introduced":"10.0.0"},{"fixed":"10.4.14"},{"introduced":"11.0.0"},{"fixed":"11.1.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/typo3/BIT-typo3-2021-21359.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
