How the Exploit Works
The vulnerability originates from an improper control of a filename that is used in a PHP ‘include’ or ‘require’ statement. An attacker can manipulate the filename, leading to the PHP Local File Inclusion (LFI). This allows an attacker to include and execute arbitrary local files within the server context, which can lead to unauthorized system access, data leakage, and potentially full system compromise.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. This example represents a malicious HTTP request:
GET /index.php?page=../../../../../etc/passwd HTTP/1.1
Host: vulnerable-website.comIn this example, the attacker is attempting to traverse the directory to read the ‘/etc/passwd’ file, which is a common target in LFI attacks due to its potential to contain sensitive user information.
Mitigation and Recommendations
Users are advised to apply the patch provided by the vendor immediately. In the absence of a patch, or until one can be applied, it’s recommended to use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure to detect and block exploit attempts.
