## Technical details

A stored Cross-Site Scripting (XSS) vulnerability exists in itsourcecode Online Hotel Management System 1.0 within the '/admin/mod_amenities/controller.php' component. The application fails to properly sanitize or escape the 'Name' parameter during a POST request when adding new amenities. This allows a remote attacker to submit a malicious payload (e.g., JavaScript within an HTML tag) that is permanently stored in the 'amenities' database table. When an administrative user subsequently views the amenities list, the malicious script executes in their browser context. This can lead to session cookie theft or unauthorized administrative actions. No authentication is reportedly required to reach the vulnerable endpoint.
