Modify search-dirctory.php to validate and sanitize user input
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules.
Configure WAF to block SQL injection patterns
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system
- Deploy intrusion detection systems to monitor for SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test the search functionality with SQL injection payloads like ' OR '1'='1 in the searchdata parameter.Check Version:
Check the application version in the admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection payloads no longer return unexpected results or database errors.📡 Detection & Monitoring
