{"id":"CVE-2022-23500","summary":"TYPO3 subject to Uncontrolled Recursion resulting in Denial of Service","details":"TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1, requesting 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. This vulnerability is very similar, but not identical, to the one described in CVE-2021-21359. This issue is patched in versions 9.5.38 ELTS, 10.4.33, 11.5.20 or 12.1.1.","aliases":["BIT-typo3-2022-23500","GHSA-8c28-5mp7-v24h"],"modified":"2026-08-27T03:30:55.156606001Z","published":"2022-12-14T07:07:05.039Z","database_specific":{"cwe_ids":["CWE-674"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23500.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"9.0.0"},{"fixed":"9.5.38"}]}],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23500.json"},{"type":"ADVISORY","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-8c28-5mp7-v24h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23500"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/typo3/typo3","events":[{"introduced":"c91b70e450c52d29ffb08115fffbb7832b15a330"},{"fixed":"8a90081d0135df5df51c49ba0b456fa3d4911720"},{"introduced":"6a5e2d4097ef0a0e3ea955af93cf83810d6fa234"},{"fixed":"7dd798416ced8107d383c4961b1c9b62b438677b"}],"database_specific":{"extracted_events":[{"introduced":"10.0.0"},{"fixed":"10.4.33"},{"introduced":"11.0.0"},{"fixed":"11.5.20"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*"}}],"versions":["v11.5.19","v11.5.18","v11.5.17","v11.5.16","v10.4.32","v11.5.15","v11.5.14","v11.5.13","v10.4.31","v11.5.12","v10.4.30","v11.5.11","v10.4.29","v11.5.10","v10.4.28","v11.5.9","v10.4.27","v11.5.8","v10.4.26","v11.5.7","v10.4.25","v10.4.24","v11.5.6","v11.5.5","v10.4.23","v10.4.22","v11.5.4","v11.5.3","v11.5.2","v11.5.1","v11.5.0","v10.4.21","v11.4.0","v10.4.20","v10.4.19","v10.4.18","v11.3.0","v10.4.17","v10.4.16","v11.2.0","v10.4.15","v10.4.14","v11.1.0","v10.4.13","v11.0.0","v10.4.12","v10.4.11","v10.4.10","v10.4.9","v10.4.8","v10.4.7","v10.4.6","v10.4.5","v10.4.4","v10.4.3","v10.4.2","v10.4.1","v10.4.0","v10.3.0","v10.2.0","v10.1.0","v10.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-23500.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
