Vulnerability Title
Admidio: CSRF and Form Validation Bypass in Inventory Item Save via `imported` Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
Admidio is an open-source user management solution. Prior to version 5.0.8, the inventory module's item_save endpoint accepts a user-controllable POST parameter imported that, when set to true, completely bypasses both CSRF token validation and server-side form validation. An authenticated user can craft a direct POST request to save arbitrary inventory item data without CSRF protection and without the field value checks that the FormPresenter validation normally enforces. This issue has been patched in version 5.0.8.
