Description
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.
