  Summary: SmartLiving anti-intrusion control panel and security system provides
  important features rarely found in residential, commercial or industrial application
  systems of its kind. This optimized-performance control panel provides first-rate
  features such as: graphic display, text-to-speech, voice notifier, flexible hardware,
  end-to-end voice transmission (voice-on-bus), IP connectivity.
  
  SMARTLAN/SI:
  The system-on-chip platform used in the SmartLAN/SI accessory board provides point-to-point
  networking capability and fast connectivity to the Internet. Therefore, it is possible
  to set up a remote connection and program or control the system via the SmartLeague
  software application. In effect, the SmartLAN/SI board grants the same level of access
  to the system as a local RS232 connection.
  
  SMARTLAN/G:
  The SmartLAN/G board operates in the same way as the SmartLAN/SI but in addition provides
  advanced remote-access and communication functions. The SmartLAN/G board is capable of
  sending event-related e-mails automatically. Each e-mail can be associated with a subject,
  an attachment and a text message. The attachment can be of any kind and is saved to an
  SD card. The message text can contain direct links to domains or IP addressable devices,
  such as a security cameras. In addition to e-mails, the SmartLAN/G board offers users
  global access to their control panels via any Internet browser accessed through a PC,
  PDA or Smartphone. In fact, the SmartLAN/G has an integrated web-server capable of
  distinguishing the means of connection and as a result provides an appropriate web-page
  for the tool in use. Smartphones can control the system in much the same way as a
  household keypad, from inside the house or from any part of the world.
  
  Desc: The devices utilizes hard-coded credentials within its Linux distribution image.
  These sets of credentials (Telnet, SSH, FTP) are never exposed to the end-user and cannot
  be changed through any normal operation of the smart home device. Attacker could exploit
  this vulnerability by logging in and gain system access.
