CVE-2023-28649Network attack vector

Device hijacking via unchecked hub ownership

Published May 22, 2023 · Updated Jan 16, 2025

Improper resource locking in Snap One OvrC before 7.3 allows remote attackers to claim managed devices by impersonating a hub. The cloud platform processes hub device-claim requests without checking whether another user already manages the discovered devices. No authentication or user interaction is required, and a successful request associates those devices with the impersonated hub.
