  1. Description:
  
  Netgear Genie installs a service called 'Fortitude HTTP' with an unquoted service path
  
  running with SYSTEM privileges.
  This could potentially allow an authorized but non-privileged local
  user to execute arbitrary code with elevated privileges on the system.
  
  2. Proof
  
  C:\Program Files>sc qc "Fortitude HTTP"
  [SC] QueryServiceConfig SUCCESS
  
  SERVICE_NAME: Fortitude HTTP
  TYPE : 110 WIN32_OWN_PROCESS (interactive)
  START_TYPE : 2 AUTO_START
  ERROR_CONTROL: 1 NORMAL
  BINARY_PATH_NAME : C:\Program Files\NetworkDLS\Fortitude HTTP\Bin
  \FortitudeSvc.exe /RunService
  LOAD_ORDER_GROUP :
  TAG: 0
  DISPLAY_NAME : NetworkDLS Fortitude HTTP
  DEPENDENCIES :
  SERVICE_START_NAME : LocalSystem
  
  
  3. Exploit:
  
  A successful attempt would require the local user to be able to insert their
  code in the system root path undetected by the OS or other security applications
  where it could potentially be executed during application startup or reboot.
  If successful, the local user's code would execute with the elevated privileges
  of the application.
