CVE-2020-5328Network attack vector

Unauthenticated cluster takeover via incomplete SyncIQ authorization

Published Mar 6, 2020 · Updated Sep 16, 2024

Unauthorized access in Dell Technologies PowerScale OneFS before 8.2.0 allows remote attackers to take control of a cluster via SyncIQ. The SyncIQ path does not perform complete authorization checks when the feature is licensed and encrypted synchronization is not required. Exploitation requires that licensed configuration; successful access exposes cluster confidentiality, integrity, and availability.
