Overview
The Common Vulnerabilities and Exposures (CVE) system has identified a critical vulnerability, designated as CVE-2025-47708, within the Drupal Enterprise Multi-Factor Authentication – Two-Factor Authentication (MFA – TFA) module. This vulnerability exposes Drupal based systems to Cross-Site Request Forgery (CSRF) attacks, potentially leading to system compromise and data leakage.
This vulnerability is of significant concern due to Drupal’s widespread use as a content management system in numerous enterprises across the globe. System compromise and data leakage pose substantial risk to the integrity, confidentiality, and availability of enterprise systems and data, which underscores the criticality of addressing this vulnerability promptly and effectively.

How the Exploit Works
Cross-Site Request Forgery, the vulnerability at the heart of this issue, takes advantage of the trust a web application has in its authenticated users. In a successful CSRF attack, an attacker tricks a victim into performing actions on their behalf on a web application in which the victim is authenticated.
In the context of CVE-2025-47708, an attacker could exploit this vulnerability to perform unauthorized actions in a Drupal-based system where the victim has authenticated. This could lead to a range of impacts, including system compromise and data leakage.
Conceptual Example Code
Here’s a conceptual example of how this vulnerability could be exploited:
POST /drupal/mfa-tfa/authenticate HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
csrf_token=...&user_action=delete_all_usersIn this example, the attacker sends a malicious HTTP POST request to the vulnerable endpoint (`/drupal/mfa-tfa/authenticate`), using a CSRF token tied to the victim’s session. The `user_action` parameter in the request body is set to `delete_all_users`, which could lead to a catastrophic impact if the victim has sufficient privileges.
Mitigation Guidance
The best mitigation strategy for this vulnerability is to apply the vendor-provided patch, which is available for all affected versions of the Drupal Enterprise MFA – TFA module. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to monitor and potentially block CSRF attacks. However, these are not long-term solutions and should be complemented with the vendor patch as soon as possible.
