Title: HomeAutomation v3.3.2 Stored and Reflected XSS
Advisory ID: ZSL-2019-5556
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 29.12.2019

Summary

HomeAutomation is an open-source web interface and scheduling solution. It was initially made for use with the Telldus TellStick, but is now based on a plugin system and except for Tellstick it also comes with support for Crestron, OWFS and Z-Wave (using OpenZWave). It controls your devices (switches, dimmers, etc.) based on an advanced scheduling system, taking into account things like measurements from various sensors. With the houseplan view you can get a simple overview of the status of your devices at their location in your house.

Description

HomeAutomation suffers from multiple stored and reflected XSS vulnerabilities when input passed via several parameters to several scripts is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site.
