Heureka Group, a prominent technology provider, has been hit by a severe security vulnerability affecting its Heureka platform. The vulnerability, dubbed CVE-2024-25931, is a Cross-Site Request Forgery (CSRF) exploit that puts users at risk of having their data compromised and accounts hijacked. This issue affects Heureka versions unspecified to 1..8. In this post, we will delve into the specifics of the vulnerability, provide a sample code snippet, link to original references, and discuss potential exploits associated with this flaw.

Vulnerability Details

The security vulnerability (CVE-2024-25931) involves a Cross-Site Request Forgery (CSRF) attack on the Heureka platform. CSRF is a type of web application vulnerability where an attacker tricks a user into executing malicious requests on their behalf. In this case, the Heureka platform failed to implement sufficient defenses against CSRF, exposing users to potential data theft and account takeover.

Affected Versions

The issue affects Heureka Platform version n/a through 1..8.

To demonstrate the vulnerability, here is a simple code snippet that exploits the CSRF flaw

<!-- CSRF exploit code -->
<html>
  <body>
    <form action="https://example.com/heureka/critical_function"; method="POST">
      <input type="hidden" name="csrfToken" value="attackerCSRFToken" />
      <input type="hidden" name="criticalData" value="attackerControlledData" />
      <input type="submit" value="Click me!" />
    </form>
  </body>
</html>

In this example, the attacker has crafted a malicious form that sends POST data to the Heureka platform's critical_function. When an unsuspecting user clicks the "Click me!" button, their browser submits the malicious data to the application, carrying out the attacker's intended action without the user's consent.
