Categories: Development, Security Created by Torben Hansen
It has been discovered that the extension "femanager" (femanager) is susceptible to Broken Access Control.

Problem Description

The extension fails to check access permissions for the edit user component. An authenticated frontend user can use the vulnerability to either edit data of various frontend users or to delete various frontend user accounts.

Another missing access check in the backend module of the extensions allows an authenticated backend user to perform various actions (userLogout, confirmUser, refuseUser and resendUserConfirmation) for any frontend user in the system.

Users of the extension are advised to update the extension as soon as possible.


Thanks to David Brauer for reporting the vulnerability in the edit user component, TYPO3 Security Team Member Torben Hansen for reporting the vulnerability in the backend module and to Stefan Busemann for providing an updated version of the extension.
