CVE-2025-58383

Arbitrary command execution via privileged bind command

Published Feb 3, 2026 · Updated Feb 3, 2026

Privilege escalation in Brocade Fabric OS before 9.2.1c2 and 9.2.2 through 9.2.2a allows remote authenticated users to run arbitrary commands. The bind component exposes an undocumented command to administrator-level accounts and executes it with privileges that bypass normal security controls. Access requires an administrator-level account from an adjacent network; successful exploitation crosses the intended privilege boundary and runs commands with elevated authority.
