🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries and input validation for the ID parameter in add_maintenance_cost.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM maintenance WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: deny requests to /maintenance/add_maintenance_cost.php containing SQL keywords in parameters
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to limit exposure
- Implement database-level controls: restrict application database user permissions to minimum required
🔍 How to Verify
Check if Vulnerable:
Test the /maintenance/add_maintenance_cost.php endpoint with SQL injection payloads in the ID parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server, SQL syntax errors in application logs, multiple failed login attempts
Network Indicators:
- HTTP requests to /maintenance/add_maintenance_cost.php containing SQL keywords like UNION, SELECT, INSERT
SIEM Query:
source="web_server" AND uri="/maintenance/add_maintenance_cost.php" AND (param="ID" AND value MATCHES "(?i)(union|select|insert|delete|drop|--|#)")
