Brocade Fabric OS OS Command Injection Vulnerability
Description

Multiple OS Command Injection vulnerabilities exist in the management interface and session processing routines of Brocade Fabric OS versions before 10.0.1. Input processing flaws during remote management connection validation and session verification for directory-based user accounts allow untrusted input containing shell metacharacters to reach internal system execution wrappers. 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.
