Details
As written in the advisory (Markdown source, shown as plain text).
### Problem
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 [TYPO3-CORE-SA-2021-005](https://typo3.org/security/advisory/typo3-core-sa-2021-005) (CVE-2021-21359).
### Solution
Update to TYPO3 versions 9.5.38 ELTS, 10.4.33 or 11.5.20 that fix the problem described above.
