## Overview

Vulnerabilities exist in the authentication module that may improperly process malformed or truncated input. An authenticated remote attacker could exploit these vulnerabilities by providing specially crafted input from a compromised or hostile authentication server. Successful exploitation could result in a Denial-of-Service or potential remote code execution with elevated privileges.

## 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`
