CVE-2022-36104Network attack vector

Service interruption via recursive error-page requests

Published Sep 13, 2022 · Updated Apr 23, 2025

Denial of service in TYPO3 CMS 11.4.0 through 11.5.15 allows remote attackers to exhaust web-server resources via invalid HTTP requests. PageContentErrorHandler resolves an inaccessible error page to the request URI, then creates another internal GET without rejecting the self-reference. No authentication or user interaction is required, but exploitation depends on error handling retrieving an inaccessible page and can interrupt the web service.
