TYPO3 CMS vulnerable to Denial of Service in Page Error Handling

Published Updated OSV record ↗

Also known as BIT-typo3-2022-23500CVE-2022-23500

Severity
  • CVSS 3.xCVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H

Affected versions

Description

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.
