Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize d_name parameter before processing
Modify export_data.php to validate d_name parameter using whitelist validation or parameterized queries
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection attempts
Add WAF rule: deny requests containing SQL keywords in d_name parameter
🧯 If You Can't Patch
- Restrict access to export_data.php using IP whitelisting or authentication
- Implement network segmentation to isolate Tongda2000 from critical databases
🔍 How to Verify
Check if Vulnerable:
Test export_data.php with SQL injection payloads in d_name parameter (e.g., d_name=' OR '1'='1)Check Version:
Check Tongda2000 version in admin panel or configuration filesVerify Fix Applied:
Test with same SQL injection payloads to confirm they are blocked or sanitized📡 Detection & Monitoring
