The flaw affects <strong>VCO On-Prem</strong> deployments, meaning organizations running the orchestrator on their own infrastructure should treat this as urgent.</p>
<p dir="auto">At this time, the source article does not provide a specific <strong>CVE ID</strong> or advisory number for this vulnerability, so no identifier is listed here. What is confirmed is that exploitation is ongoing, which raises the priority for affected administrators to patch without delay.</p>
<p dir="auto">Mitigation steps to consider:</p>
<ul>
<li>Apply the security patches released by <strong>Arista Networks</strong> as soon as possible.</li>
<li>Prioritize <strong>VCO On-Prem</strong> instances, since those are the deployments confirmed to be affected.</li>
<li>Monitor your environment for signs of compromise and review access logs for unusual activity.</li>
<li>If you cannot patch immediately, restrict exposure of the orchestrator to trusted networks and limit administrative access.</li>
</ul>
<p dir="auto">If your organization relies on <strong>VeloCloud Orchestrator</strong> for SD-WAN management, confirm whether you are running an on-premises deployment and verify your patch status against Arista's guidance.</p>
