## Overview

A security vulnerability has been detected in Ubiquiti EdgeRouter X up to 2.0.9-hotfix.6. The affected element is an unknown function of the component Web Management Interface. The manipulation of the argument dpi leads to command injection. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. There are still doubts about whether this vulnerability truly exists. The vendor position is that post-authentication issues are not accepted as vulnerabilities.

## Affected

- `er-x_firmware < 2.0.9`
- `er-x_firmware = 2.0.9`
- `er-x-sfp_firmware < 2.0.9`
- `er-x-sfp_firmware = 2.0.9`

## Remediation

Upgrade past the affected range:

- `er-x_firmware 2.0.9`
- `er-x-sfp_firmware 2.0.9`
