Description : Concrete CMS 9.
- 2 and below is vulnerable to Cross-Site Request Forgery (CSRF) in the Express "Clear Entries" function (POST /index. php/dashboard/system/express/entities/delete_entries) because the controller records but does not enforce a failed CSRF token check, allowing the destructive operation to proceed when the token is missing or invalid.
A remote unauthenticated attacker can force an authenticated administrator who visits an attacker-controlled page to permanently delete all entries belonging to an attacker-selected Express entity on a web application to which the administrator is currently authenticated. Because the default Contact Express object ships with a fixed entity UUID, the target identifier can be obtained without dashboard access.
