🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates 2. If patch available, download and apply 3. Test functionality after update 4. Monitor for any issues
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize 'appointment' parameter before processing
Modify /cancelbookingpatient.php to validate appointment parameter using prepared statements or parameterized queries
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule: deny requests containing SQL keywords like UNION, SELECT, INSERT, DELETE in appointment parameter
🧯 If You Can't Patch
- Disable or restrict access to /cancelbookingpatient.php endpoint
- Implement network segmentation to isolate the booking system from critical databases
🔍 How to Verify
Check if Vulnerable:
Test /cancelbookingpatient.php with SQL injection payloads in appointment parameter; monitor for database errors or unexpected responses.Check Version:
Check software version in admin panel or configuration files; default is 1.0.Verify Fix Applied:
Attempt SQL injection after applying fixes; verify no database errors occur and input is properly sanitized.📡 Detection & Monitoring
Log Indicators:
