🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Implement parameterized queries or input validation in editbill.php. Replace raw SQL queries with prepared statements.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the 'id' parameter before processing
// In editbill.php, add: $id = filter_var($_GET['id'], FILTER_VALIDATE_INT); if (!$id) { die('Invalid input'); }
Web Application Firewall Rule
allBlock SQL injection patterns targeting editbill.php
ModSecurity rule: SecRule REQUEST_URI "@contains editbill.php" "id:1001,phase:2,deny,msg:'SQLi attempt on editbill.php'"
🧯 If You Can't Patch
- Restrict network access to the Vehicle Management System using firewall rules
- Implement database user with minimal permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test editbill.php with SQL injection payloads like: editbill.php?id=1' OR '1'='1Check Version:
Check PHP files for version comments or review application documentationVerify Fix Applied:
Attempt SQL injection tests and verify they are blocked or produce error messages without database interaction📡 Detection & Monitoring
