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.
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.
The frame
HTTP query parameter is now ignored, since it could not be used by core APIs.
The new feature flag security.frontend.allowInsecureFrameOptionInShowImageController
â which is disabled per default â can be used to reactivate the previous behavior.
Thanks to TYPO3 security team member Torben Hansen who reported this issue and to TYPO3 core & security team members Benjamin Mack and Benjamin Franzke who fixed the issue.
