CVE-2024-34358

TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController

5.3 MediumFix available

TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the ShowImageController (_eID tx_cms_showpic_) lacks a cryptographic HMAC-signature on the frame HTTP query parameter (e.g. /index.php?eID=tx_cms_showpic?file=3&...&frame=12345). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 fix the problem described.

TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController

Problem

The ShowImageController (eID tx_cms_showpic) lacks a cryptographic HMAC-signature on the frame HTTP query parameter (e.g. /index.php?eID=tx_cms_showpic?file=3&...&frame=12345). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side.

Solution

Update to TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 that fix the problem described.

ℹ️ Strong security defaults - Manual actions required

The frame HTTP query parameter is now ignored, since it could not be used by core APIs.

The new feature flag security.frontend.allowInsecureFrameOptionInShowImageController – which is disabled per default – can be used to reactivate the previous behavior.
