How the Exploit Works

The vulnerability exists due to an improper validation of uploaded files in the “Create Services” file of the SourceCodester Company Website CMS 1.0. This allows an attacker to exploit the vulnerability by uploading a malicious file, which could potentially lead to remote code execution. The attacker could then gain unauthorized access to the system, possibly leading to a system compromise or data leakage.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited using an HTTP request:

POST /dashboard/Services HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="exploit.php"
Content-Type: application/x-php
<?php
// malicious code
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In this example, the attacker is uploading a file named `exploit.php` that contains malicious PHP code. Once uploaded, the file can be accessed by the attacker to execute the malicious code on the server, potentially leading to a system compromise or data leakage.

Countermeasures and Mitigation

To mitigate the risk associated with this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These security measures can help detect and block malicious file uploads, thus preventing the exploitation of this vulnerability.
