## Overview

In Versa Director, the command injection is an attack in which the goal is execution of arbitrary commands on the host operating system via a vulnerable application. Command injection attacks are possible when an application passes unsafe user supplied data (forms, cookies, HTTP headers etc.) to a system shell. In this attack, the attacker-supplied operating system commands are usually executed with the privileges of the vulnerable application. Command injection attacks are possible largely due to insufficient input validation.

## Affected

- `versa_director < 16.1R2S11`
- `versa_director >= 20.2.0, < 20.2.2`
- `versa_director >= 21.1.0, < 21.1.1`
- `versa_director >= 21.2.0, < 21.2.1`

## Remediation

Upgrade past the affected range:

- `versa_director 21.2.1`
