CVE-2023-23689Network attack vector

Unauthenticated service interruption via resource exhaustion

Published Feb 28, 2023 · Updated Mar 7, 2025

Uncontrolled resource consumption in Dell PowerScale OneFS on listed nodes allows remote attackers to interrupt service without authentication. Dell identifies integrated hardware management software as the locus but has not disclosed the resource, request, or missing limit that permits consumption. Network access to an A200, A2000, H400, H500, H600, H5600, F800, or F810 node is sufficient; exhaustion impairs hardware management and triggers OneFS data protection, causing a service interruption.
