Background

TYPO3 is an open-source content management system (CMS) that allows users to create and manage websites. It provides a backend interface for administrators to configure and control various aspects of the CMS. However, a security misconfiguration vulnerability exists in TYPO3 versions 8.0.0 to 8.7.23 and 9.0.0 to 9.5.4. This vulnerability can result in the persistence of insecure or empty credentials for backend user accounts, posing a risk to custom authentication service implementations.

Vulnerability Detail

When creating new backend user accounts in TYPO3, insecure or empty credentials may be stored in the database. Changing the type of user account triggers a reload of the backend form, which can lead to the persistence of the current state. This means that backend user accounts may contain empty or weak credentials, such as empty usernames or passwords. While the TYPO3 core does not allow the use of empty usernames or passwords, this vulnerability can still be exploited by custom authentication service implementations. It is important to note that this vulnerability requires interaction by a backend user with appropriate privileges.

How To Fix

Fixed versions by release line

The minimum fixed version depends on the release line you run.

  • >= 8.0.0, < 8.7.23 8.7.23
    composer require typo3/cms:8.7.23
  • >= 9.0.0, < 9.5.4 9.5.4
