How the Exploit Works

This vulnerability allows an attacker to bypass the multi-factor authentication mechanism in Drupal due to an error in the way the system handles authentication requests. By exploiting this flaw, an attacker can gain access to the system without providing accurate authentication credentials. In essence, it opens an alternate path or channel for unauthorized access to the system.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited using HTTP request. The attacker sends a POST request to a vulnerable endpoint with a malicious payload.

POST /drupal/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"auth_payload": "bypass_auth_token"
}

In this example, the “bypass_auth_token” is a placeholder for an actual malicious payload that would exploit the vulnerability, bypassing the multi-factor authentication process.
