Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious payloads
Input Validation Filter
allImplement application-level input validation to reject SQL special characters
🧯 If You Can't Patch
- Implement strict network segmentation to isolate the vulnerable system
- Deploy database activity monitoring to detect SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Check system version against affected date range; test input fields with SQL injection payloads in non-production environment
Check Version:
Check application interface or contact vendor for version information
Verify Fix Applied:
Verify version is 12.12.2023 or later; conduct SQL injection testing to confirm remediation
