CVE-2024-35560: IDCCMS v1.35 Vulnerable to Cross-Site Request Forgery (CSRF) Exploit

A recent vulnerability discovered in IDCCMS v1.35, a popular content management system, exposes it to a Cross-Site Request Forgery (CSRF) attack. An attacker may exploit the vulnerability to interfere with the system's authentication mechanisms and launch privilege escalation attacks. This long read post will elaborate on the CVE-2024-35560 vulnerability, provide source code snippets to demonstrate how it works, and link to original references for further investigation.

CVE-2024-35560 Exploit Details

The IDCCMS v1.35 CSRF vulnerability resides in the '/admin/ca_deal.php?mudi=del&dataType=&dataTypeCN' component. A malicious attacker can exploit this weakness to make the system function incorrectly or expose confidential information. The attacker generates a malicious link or a specially crafted HTML form that, upon being clicked or submitted by an authenticated user, sends a CSRF token to the application. This allows the attacker to make requests using the victim's privileges, such as delete or modify data.

Code Snippet Demonstrating the Vulnerability

The following code snippet demonstrates the vulnerability. The attacker creates a simple HTML form that includes a hidden field containing the CSRF token value and a button that automatically submits the form when clicked:

<html>
  <body>
    <h1>Example of CSRF Exploit</h1>
    <form action="http://example.com/admin/ca_deal.php?mudi=del&dataType=&dataTypeCN"; method="POST">
      <input type="hidden" name="csrf_token" value="malicious_token_here" />
      <input type="submit" value="Click me to exploit the vulnerability!" />
    </form>
  </body>
</html>

Upon clicking the button, the CSRF token is sent to the '/admin/ca_deal.php?mudi=del&dataType=&dataTypeCN' component, causing potential damage to the system.

Preventing CSRF Exploits

To defend against CSRF attacks, IDCCMS developers should adopt strong security measures. Such measures include using a secure and random token generated on every request, securely stored in server-side session data. Additionally, developers must validate the form submission and check for the presence of the CSRF token before processing the request.
