CVE-2025-58382

Root command execution via insecure CLI authentication

Published Feb 3, 2026 · Updated Feb 3, 2026

Authentication bypass in Brocade Fabric OS before 9.2.1c2 and 9.2.2 through 9.2.2a allows remote authenticated users to execute commands as root. Broadcom has not published which authentication or management-service configuration error lets supportsave, seccertmgmt, and configupload cross the root boundary. Administrative credentials and network access to the switch management interface are required; successful exploitation grants unrestricted root command execution.
