Official description
Multiple OS Command Injection vulnerabilities exist in the management interface and session processing routines of Brocade Fabric OS versions before 10.0.1.

An authenticated user or a compromised directory service account can exploit these vulnerabilities to execute arbitrary operating system commands with elevated privileges on the target device.
