Modify /pages/purchase_delete.php to use prepared statements with parameterized queries
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection attempts
Add WAF rule: deny requests with SQL keywords in pr_id parameter
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules to only trusted IP addresses
- Implement database-level controls: use least privilege accounts, enable logging, and restrict database permissions
🔍 How to Verify
Check if Vulnerable:
Test the /pages/purchase_delete.php endpoint with SQL injection payloads in the pr_id parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and that parameterized queries are implemented📡 Detection & Monitoring
