Vulnerable Location
Affected File: app/classes/Master.php:300; app/classes/Master.php:302; app/classes/Master.php:305; app/admin/employees/manage_employee.php:94; app/admin/employees/manage_employee.php:100
Affected Component: employee avatar upload extension rendered in hidden field and image src
Vulnerable Parameter / Field: employee avatar filename
Affected Endpoint: POST /classes/Master.php?f=save_employee; render /admin/employees/manage_employee.php?id=12
HTTP Method: POST
Render / Trigger Location: /admin/employees/manage_employee.php?id=12
Authentication Requirement: authenticated admin employee create/update; admin employee edit view triggers
Vulnerability Overview
The Online Leave Management System application does not properly encode or sanitize user-controlled input submitted through employee avatar filename. The value is later rendered in a browser context within /admin/employees/manage_employee.php?id=12, which allows JavaScript execution when the affected page is opened. This results in a filename cross-site scripting vulnerability. |
