Adobe Commerce, Cross-Site Request Forgery (CSRF), CVE-2025-27189 (Medium)

CVE-2025-27189 is a CSRF vulnerability in Adobe Commerce that allows attackers to trick authenticated users into executing unintended actions, potentially leading to a denial-of-service (DoS) condition. The flaw exists in versions 2.4.7-p4, 2.4.6-p9, 2.4.5-p11, 2.4.4-p12, 2.4.8-beta2, and earlier.
When a logged-in admin or privileged user visits a malicious webpage, the attacker can forge a request (e.g., deleting critical data or overloading system resources) via crafted HTML forms or JavaScript. Since the browser automatically includes session cookies, the server processes the request as legitimate. The attack relies on social engineering to lure victims into clicking a malicious link. Adobe Commerce fails to validate CSRF tokens properly in certain endpoints, enabling this exploit.

DailyCVE Form:

Platform: Adobe Commerce
Version: <=2.4.8-beta2
Vulnerability: CSRF to DoS
Severity: Medium
Date: 04/30/2025

What Undercode Say:

Exploitation:

1. Craft a malicious HTML form targeting Adobe Commerce endpoints:

   </li>
   </ol>
   
   <form action="https://target.com/admin/deleteAll" method="POST">
   <input type="hidden" name="confirm" value="1">
   </form>
   
   <script>document.forms[bash].submit();</script>
   

   2. Host the payload on a compromised site and trick admins into visiting it.

   Detection:

   Check for missing CSRF tokens in admin actions:

   grep -r "adminhtml" app/code/ --include=".php" | grep -L "csrf"
   

   Mitigation:

   1. Apply Adobe’s patch or upgrade to fixed versions.
   2. Enforce CSRF token validation in all state-changing endpoints:

      $this->validateRequest($this->getRequest()->getParam('form_key'));
      

   3. Use Content Security Policy (CSP) headers to restrict external scripts:

      Header set Content-Security-Policy "default-src 'self'"
