<p>A vulnerability in the key-based SSH authentication mechanism of Cisco&nbsp;Umbrella Virtual Appliance (VA) could allow an unauthenticated, remote attacker to impersonate a VA.</p>
<p>This vulnerability is due to the presence of a static SSH host key. An attacker could exploit this vulnerability by performing a man-in-the-middle attack on an SSH connection to the Umbrella VA. A successful exploit could allow the attacker to learn the administrator credentials, change configurations, or reload the VA.</p>
<p><strong>Note</strong>: SSH is not enabled by default on the Umbrella VA.</p>
