🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries and input validation for the ID parameter in ajax.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('DELETE FROM attendance WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall (WAF) Rules
allBlock SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests to /ajax.php?action=delete_employee_attendance_single with SQL injection patterns in ID parameter
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all traffic to/from the vulnerable system
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: /ajax.php?action=delete_employee_attendance_single&ID=1' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
