The create and edit flows do not restrict which user properties may be submitted and do not enforce access control on the frontend user group assignment. As a result, an attacker can assign an arbitrary frontend user group to a newly registered or edited account, gaining unauthorized access to content and functionality restricted to privileged frontend user groups.

Affected: Packagist: evoweb/sf-register

The `create` and `edit` flows in the TYPO3 extension sf_register do not restrict which user properties may be submitted, and do not enforce access control on the frontend user group assignment. As a result, an attacker can assign an arbitrary frontend user group to a newly registered or edited account, gaining unauthorized access to content and functionality restricted to privileged frontend user groups.

Ein Angreifer kann mehrere Schwachstellen in TYPO3 Extensions ausnutzen, um beliebigen Programmcode auszuführen, um einen SQL-Injection Angriff durchzuführen, um Informationen offenzulegen, und um Sicherheitsvorkehrungen zu umgehen.
