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.
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.
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.
Tested on: GNU/Linux 3.2.1 armv5tejl
