Brocade Fabric versions before 9.2.2d and 10.0.0 through 10.0.0a1 handling of specific download protocols utilizes unsanitized parameter strings. When processing upgrade requests, parameters are converted into system command strings and executed through a system shell interface. Because control characters and shell metacharacters in fields like the host or file path are not stripped or sanitized, an attacker can execute arbitrary shell commands with the firmware management daemon's elevated privileges.
