## Overview

An unauthenticated arbitrary file write vulnerability exists in an API endpoint of AOS-CX. Successful exploitation of this vulnerability allows an attacker to write arbitrary files to the underlying operating system, which could lead to remote code execution.

## Affected

- `arubaos-cx < 10.10.1181`
- `arubaos-cx >= 10.13.0000, < 10.13.1190`
- `arubaos-cx >= 10.16.0000, < 10.16.1060`
- `arubaos-cx >= 10.17.0000, < 10.17.1030`
- `arubaos-cx = 10.18.0001`

## Remediation

Upgrade past the affected range:

- `arubaos-cx 10.17.1030`
