Robtex Viking Web Server permits traversal out of HTTP docs root directory

Overview

Viking v1.07 is a ‘multi-protocol-internet-server’ available from <http://www.robtex.com>. A vulnerability exists with this web server which allows a remote user to see any file on the server with read permissions enabled.

Description
