Summary
The TYPO3 CMS Backend has Broken Authentication in Backend MFA
Details

Problem

The multifactor authentication (MFA) dialog presented during backend login can be bypassed due to insufficient enforcement of access restrictions on all backend routes.

Successful exploitation requires valid backend user credentials, as MFA can only be bypassed after successful authentication.

Solution

Update to TYPO3 versions 12.4.31 LTS, 13.4.12 LTS that fix the problem described.
