1) Introduction
===============


> From vendor's website:
"Client Management Services® (CMS) includes all the server-based
services (PXE Server, BOOTP Server) and administration tools needed to
setup an open network boot environment. You can deploy your favorite
third party client management tools in a pre-OS booting phase."

2) Bug

The TFTP Boot Server is affected by a classical directory traversal
vulnerability which allows an attacker to download (upload is not
allowed) any file from the disk where is located the tftp folder.
