CVE-2018-25187
📋 TL;DR
CVE-2018-25187 allows unauthenticated attackers to directly download the kim.db database file containing user credentials and password hashes, and execute SQL injection attacks through the menu endpoint. This affects Tina4 Stack version 1.0.3 deployments, potentially exposing all user data and allowing database manipulation.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including credential theft, data exfiltration, and potential remote code execution via SQL injection.
Likely Case
Unauthenticated attackers steal user credentials and password hashes, then use them for further attacks or data manipulation.
If Mitigated
Limited impact if database contains no sensitive data or is properly segmented from production systems.
🎯 Exploit Status
Exploit code is publicly available and requires no authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.0.4 or later
Vendor Advisory: https://github.com/andrevmartins/Tina4Stack
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Upgrade to Tina4 Stack version 1.0.4 or later. 3. Restart the Tina4 Stack service. 4. Verify the fix by testing database file access and SQL injection vectors.
🔧 Temporary Workarounds
Database File Access Restriction
allBlock direct access to kim.db file via web server configuration.
For Apache: <Files "kim.db">
Require all denied
</Files>
For Nginx: location ~ \.db$ {
deny all;
}
Input Validation for Menu Endpoint
allImplement parameter validation and SQL injection filtering for menu endpoint.
Implement prepared statements and parameterized queries in menu endpoint code.
🧯 If You Can't Patch
- Isolate Tina4 Stack deployment behind a WAF with SQL injection protection rules.
- Implement network segmentation to restrict access to only trusted users and systems.
🔍 How to Verify
Check if Vulnerable:
Attempt to access http://[target]/kim.db directly. If database downloads, system is vulnerable. Test SQL injection via menu endpoint parameters.Check Version:
Check Tina4 Stack version in configuration files or via application interface.Verify Fix Applied:
Verify kim.db file cannot be accessed directly and SQL injection attempts via menu endpoint are blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- HTTP requests for kim.db file
- Unusual SQL queries in application logs
- Multiple failed login attempts following database access
Network Indicators:
- Unusual outbound database connections
- Large data transfers from kim.db file downloads
SIEM Query:
source="web_logs" AND (uri="/kim.db" OR uri LIKE "%/menu?%" AND (param CONTAINS "' OR" OR param CONTAINS "--"))
