## Overview

Kiteworks Email Protection Gateway rejected certain configuration settings, but its validation did not recognize every form in which they could be supplied. An authenticated administrator could potentially use an unrecognized form to have a file of their choosing written to the gateway and executed, resulting in code execution as the gateway service account.

## Affected

- `kiteworks < 9.5.0`

## Remediation

Upgrade past the affected range:

- `kiteworks 9.5.0`
