🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing parameterized queries and input validation as temporary fix.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for itr_no and dental_no parameters
Modify dental_form.php to use prepared statements with parameter binding
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting dental_form.php
Add WAF rule: Block requests with SQL keywords in itr_no/dental_no parameters
🧯 If You Can't Patch
- Block external access to /dental_form.php endpoint using firewall rules
- Implement network segmentation to isolate the vulnerable system from sensitive data
🔍 How to Verify
Check if Vulnerable:
Test /dental_form.php endpoint with SQL injection payloads in itr_no or dental_no parametersCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify parameterized queries are implemented and test with SQL injection payloads returns errors instead of successful queries📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server
- Multiple failed login attempts or SQL errors in application logs
