Summary
TYPO3 CMS vulnerable to Denial of Service in Page Error Handling
Details

Meta

  • CVSS: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:F/RL:O/RC:C (5.5)

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 the same as described in TYPO3-CORE-SA-2021-005 (CVE-2021-21359). A regression, introduced during TYPO3 v11 development, led to this situation.

Solution

Update to TYPO3 version 11.5.16 that fixes the problem described above.

Credits

Thanks to Rik Willems who reported this issue and to TYPO3 core & security team member Oliver Hader who fixed the issue.
