The Kaspersky Sandbox web interface is protected against CSRF attacks and operates only if the web interface user's browser provides the Referrer header of an HTTP POST request. Make sure that the browser that you are using to work with the Sandbox web interface does not modify the Referrer header of an HTTP POST request. If the connection with the web interface is established through a proxy server of your organization, check the settings and make sure that the proxy server does not modify the Referrer header for an HTTP POST request.
To begin working with the Kaspersky Sandbox web interface, proceed as follows:
