🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No

allAdd server-side validation to sanitize the 'id' parameter to accept only numeric values.
Modify /view_students.php to include: if(!is_numeric($_GET['id'])) { die('Invalid input'); }
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the vulnerable endpoint.
Add WAF rule: SecRule ARGS:id "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test /view_students.php?id=1' OR '1'='1 to see if it returns SQL errors or unexpected data.Check Version:
Check application version in admin panel or configuration files.Verify Fix Applied:
Attempt the same SQL injection test and verify it's blocked or returns an error message without executing.📡 Detection & Monitoring
