🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries manually or migrating to alternative software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to ensure viewid parameter contains only numeric values
Modify /admin/view-foreigner-ticket.php to validate $_GET['viewid'] with is_numeric() or filter_var()
Web Application Firewall Rule
allBlock SQL injection patterns targeting the viewid parameter
Add WAF rule: deny requests to /admin/view-foreigner-ticket.php with SQL keywords in viewid parameter
🧯 If You Can't Patch
- Isolate the system on a separate network segment with strict access controls
- Implement database-level protections: use least privilege accounts, enable SQL injection prevention features
🔍 How to Verify
Check if Vulnerable:
Test /admin/view-foreigner-ticket.php?viewid=1' OR '1'='1 and observe if SQL error or unexpected behavior occursCheck Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Test with same payload after implementing fixes - should return error page or sanitized response without SQL errors📡 Detection & Monitoring
