DescriptionCVE.org

Improper Input Validation in Zoom Rooms for Windows before 6.6.5 in Kiosk Mode may allow an authenticated user to conduct an escalation of privilege via local access.

Executive ViewAI

Why It Matters

Zoom Room versions up to 6.6.5 contain an input validation vulnerability that could allow attackers to compromise meeting room systems. This affects organizations using Zoom Rooms for conference infrastructure, potentially impacting business continuity and meeting security until remediation is deployed.

Business Impact: High

Compensating Controls

Implement network segmentation to isolate Zoom Room devices; restrict administrative access via VPN/firewall rules; disable remote management features if not actively required; monitor Zoom Room system logs for suspicious input patterns; disable guest access to room systems; enforce strong authentication for room controls; regularly audit device configurations for unauthorized changes.
