Concrete CMS Cross-Site Request Forgery Vulnerability in Express Association Reorder Dialog

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in Concrete CMS versions 9 prior to 9.5.0. The issue resides in the Express Association Reorder dialog, where the application fails to properly validate CSRF tokens before processing requests. This vulnerability allows an attacker to manipulate the order of associations by causing an authenticated user to unknowingly submit a request that alters association data.

Impact

Exploitation of this vulnerability allows for Cross-Site Request Forgery, where an attacker can trick an authenticated user into performing actions without their consent, potentially leading to unauthorized changes in the application.

Remediation

Users can upgrade to Concrete CMS version 9.5.0 or later, where this vulnerability has been fixed.
