## Overview

An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that regenerates credentials will expose that component's administrative interface to anyone aware of the default value.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
