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


The Sentinel Protection and Key Server are two simple webservers for
the monitoring of the licenses and listen respectively on ports 6002
and 7002.

2) Bug
======


Both the webservers are affected by a directory traversal
vulnerability exploitable using the backslash delimiter (the servers
don't support hex chars) allowing an attacker to download any file in
the disk on which the services are installed.

It's funny to note that the security patch available from November 2007
was released just to fix a directory traversal vulnerability but they
dropped only the slash delimiter leaving the backslash working.
