How CVE-2025-40622 Works
This vulnerability exploits improper input sanitization in the `username` parameter of the `GetLastDatePasswordChange` endpoint in TCMAN GIM v11. An attacker can craft a malicious SQL query, injecting it through this parameter. Due to lack of prepared statements or input validation, the backend database executes the injected payload, allowing unauthorized access to sensitive data. The exploit leverages UNION-based or blind SQLi techniques to extract, modify, or delete records. The CVSS 4.0 score of 9.3 (CRITICAL) reflects its network-based exploitability, low attack complexity, and high impact on confidentiality, integrity, and availability.
DailyCVE Form
Platform: TCMAN GIM
Version: v11
Vulnerability: SQL Injection
Severity: Critical
Date: 2025-05-06
What Undercode Say:
Exploitation
1. Identify vulnerable endpoint:
POST /GetLastDatePasswordChange HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded username=admin'--
2. Extract database version:
username=admin' UNION SELECT 1,@@version,3--
3. Dump table names:
username=admin' UNION SELECT 1,table_name,3 FROM information_schema.tables--
Protection
1. Input validation:
import re def sanitize_input(input_str): return re.sub(r"[;--'\"\/]", "", input_str)
2. Prepared statements:
String query = "SELECT FROM users WHERE username = ?"; PreparedStatement stmt = conn.prepareStatement(query); stmt.setString(1, username);
3. WAF rules:
location / {
modsecurity_rules '
SecRule ARGS "@detectSQLi" "id:1001,deny,status:403"
';
}
4. Patch: Upgrade to TCMAN GIM v12+ or apply vendor-provided fixes.
5. Logging:
grep -i "sql error" /var/log/tcman/access.log
6. Mitigation: Restrict database user permissions:
REVOKE DELETE, DROP ON . FROM 'app_user'@'%';
7. Exploit detection:
if "' OR '1'='1" in request.query: block_request()
