🔍 How to Verify
Check if Vulnerable:
Test vulnerable parameters with SQL injection payloads (e.g., ' OR '1'='1) in the /SchoolERP/office_admin/ endpointCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Retest with SQL injection payloads after remediation; successful payloads should be rejected or sanitized📡 Detection & Monitoring
