## Overview

An OS command injection vulnerability exists in the PAM (Pluggable Authentication Module) session cleanup routines during SSH session termination on Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user authenticating via an external directory or AAA service whose username or profile identifier contains shell metacharacters can trigger arbitrary command execution with root privileges when their remote SSH session closes.
