🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider replacing with alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side input validation to filter SQL injection patterns in the txt_uname_email parameter
Modify index.php to add parameter sanitization before database queries
Web Application Firewall
allDeploy WAF with SQL injection rules to block malicious requests
Configure WAF to block SQL injection patterns in POST parameters
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input validation
- Implement database user with minimal permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test the txt_uname_email parameter with SQL injection payloads like ' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with SQL injection payloads and verify they are rejected or sanitized📡 Detection & Monitoring
