🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameter validation and prepared statements to /Admin/InsertCity.php
Edit InsertCity.php to use prepared statements: $stmt = $conn->prepare('INSERT INTO cities (state_id, city_name) VALUES (?, ?)'); $stmt->bind_param('is', $cmbState, $cityName);
Web Application Firewall Rules
allBlock SQL injection patterns targeting cmbState parameter
Add WAF rule: SecRule ARGS:cmbState "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Block external access to /Admin/ directory via firewall rules or .htaccess
- Implement network segmentation to isolate the vulnerable system from sensitive databases
🔍 How to Verify
Check if Vulnerable:
Test /Admin/InsertCity.php with SQL injection payloads in cmbState parameter (e.g., ' OR '1'='1)Check Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Verify prepared statements are implemented and test with SQL injection payloads that should be rejected📡 Detection & Monitoring
