https://docs.imperihome.com/app/iss

Affected version: 0.2.40

Summary: REST Gateway between Domoticz and Imperihome ISS. Domoticz is a home automation

system with a pretty wide library of supported devices, ranging from weather stations to

smoke detectors to remote controls, and a large number of additional third-party integrations

are documented on the project's website. It is designed with an HTML5 frontend, making it

accessible from desktop browsers and most modern smartphones, and is lightweight, running

on many low-power devices like the Raspberry Pi.

Desc: MyDomoAtHome REST API is affected by an information disclosure vulnerability due to

improper access control enforcement. An unauthenticated remote attacker can exploit this,

via a specially crafted request to gain access to sensitive information.

Tested on: NodeJS: 10.15.0, 8.15.1, 8.15.0, 8.11.1, 8.9.4, 4.8.7, 4.2.2

Webmanager/Engine: EJS
