Senserva AI Opinion for CVE-2025-1976
Broadcom Brocade Fabric OS allows a local user with administrative privileges to execute arbitrary code with full root privileges, CVSS 6.7. An admin-to-root jump on SAN fabric switches sounds academic until you note confirmed exploitation since April 2025: attackers who capture switch credentials use it to embed themselves beneath the management layer of storage infrastructure.
Do this: Update Fabric OS on Brocade switches and audit which accounts hold admin rights on the fabric.
