HomeAutomation v3.3.2 CSRF Add Admin Exploit

Vendor: Tom Rosenback and Daniel Malmgren
Product web page: http://karpero.mine.nu/ha/
Affected version: 3.3.2

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.

Desc: The application interface allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the requests. This can
be exploited to perform certain actions with administrative privileges if a logged-in
user visits a malicious web site.

Tested on: Apache/2.4.41 (centos) OpenSSL/1.0.2k-fips
Apache/2.4.29 (Ubuntu)
PHP 7.2.24-0ubuntu0.18.04.1
