How the Exploit Works

The vulnerability, CVE-2025-48445, arises from incorrect authorization checks in the Drupal Commerce Eurobank (Redirect) module. An attacker can exploit this via network to misuse functionality, which could potentially lead to unauthorized access to sensitive data or even a full system compromise. The attack requires low privileges and no user interaction, which makes it particularly dangerous.

Conceptual Example Code

To understand how an attacker might exploit this vulnerability, consider this conceptual example:

POST /drupal-commerce/eurobank-redirect HTTP/1.1
Host: target.example.com
Authorization: Bearer incorrect-auth-token
{
"transaction_id": "123456",
"amount": "1000",
"redirect": "http://malicious-url.com"
}

In this conceptual example, the attacker sends a POST request to the vulnerable endpoint, `/drupal-commerce/eurobank-redirect`. The attacker uses an incorrect or expired auth token but due to the incorrect authorization vulnerability, the request is processed. The attacker misuses the redirect functionality to redirect the transaction to a malicious URL, potentially compromising the system or leaking sensitive data.

Mitigation

To mitigate this vulnerability, users of the Drupal Commerce Eurobank (Redirect) module should immediately apply the vendor patch. The patch addresses this vulnerability by correctly implementing authorization checks. In cases where the patch cannot be immediately applied, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these should not be considered long-term solutions, and the patch should be applied as soon as possible.
