• EPSS: 0.5% probability of exploitation in the next 30 days

Description

TYPO3 is an open source, PHP based web content management system. In versions on the 12.x branch prior to 12.4.31 LTS and the 13.x branch prior to 13.4.2 LTS, 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. Users should update to TYPO3 version 12.4.31 LTS or 13.4.12 LTS to fix the problem.

Affected products

• typo3: from 12.0.0 before 12.4.31; from 13.0.0 before 13.4.12 — fixed in 12.4.31, 13.4.12

How to fix

Upgrade to a fixed version: typo3 12.4.31, 13.4.12. Check the vendor advisory for mitigations.
