CVE-2023-28412Network attack vector

Unauthenticated device information disclosure via MAC enumeration

Published May 22, 2023 · Updated Jan 16, 2025

Information disclosure in Snap One OvrC Cloud before 7.3 allows remote attackers to obtain device details using arbitrary MAC addresses. The cloud lookup accepts attacker-supplied MAC addresses without establishing device association and returns records for matching devices. No authentication or user interaction is required, and repeated requests permit enumeration of device information stored by the service.
