Authentication Bypass in TYPO3 CMS
The advisory, in context
The default authentication service misses to invalidate empty strings as password. Therefore it is possible to authenticate backend and frontend users without password set in the database. Note: TYPO3 does not allow to create user accounts without a password. Your TYPO3 installation might only be affected if there is a third party component creating user accounts without password by directly manipulating the database.
