Description

An OS command injection vulnerability exists in maintenance command-line diagnostic utilities on Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. The binary fails to sanitize user-supplied input options when invoking underlying system commands through a shell interpreter. A privileged user with maintenance account access can exploit this issue by supplying crafted parameters, which results in arbitrary OS command execution with root privileges.
