Title: TYPO3 Uncontrolled Recursion Vulnerability
Overview:

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.
