GMS-2022-8130: Duplicate of ./packagist/typo3/cms-core/CVE-2022-23500.yml

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 (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.
