Advisory: ActiveWeb Contentserver CMS Editor Permission Settings Problem
RedTeam Pentesting discovered a problem with the permission settings in the management interface of the activeWeb contentserver CMS during a penetration test. The ability of an editor to create and edit documents can be restricted to specific folders. RedTeam Pentesting was still able to create arbitrary documents in all directories, regardless of the restrictions set on the editor account.

contentserver is the comprehensive, scalable Content Management System for professional requirements. It combines editorial system, website management and development platform for web applications in one package.
(translation of the description on the vendor's homepage)
When creating new editor accounts, the administrator has the ability to impose restrictions on it. The editor can be restricted to be only able to create and modify files in certain folders. All other folders should be inaccessible to him. The vulnerability lies in the fact that an editor with such a restricted account is still able to create files in arbitrary locations. He will not be able to edit already existing pages though.
The vulnerability is fixed in release 5.6.2964.
