CVE-2025-27086Network attack vector

Unauthenticated GUI access via undisclosed authentication flaw

Published Apr 21, 2025 · Updated Apr 22, 2025

Authentication bypass in HPE Performance Cluster Manager 1.12 and earlier allows remote attackers to access the GUI without credentials. Vendor evidence identifies a maliciously crafted GUI communicating with the server through RMI but does not disclose the flawed authentication operation. Network access to the admin node's GUI service is required, and exploitation can expose, alter, or interrupt cluster management.
