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: Unauthenticated Server-Side Request Forgery (SSRF) vulnerability exists in the  
SmartLiving SmartLAN within the GetImage functionality. The application parses user  
supplied data in the GET parameter 'host' to construct an image request to the service  
through onvif.cgi. Since no validation is carried out on the parameter, an attacker  
can specify an external domain and force the application to make an HTTP request to  
an arbitrary destination host. This can be used by an external attacker for example  
to bypass firewalls and initiate a service and network enumeration on the internal  
network through the affected application.  
Tested on: GNU/Linux 3.2.1 armv5tejl
