Finding: Unauthenticated Local File Inclusion
Credit: Leopold von Niebelschuetz-Godlewski of Trustwave SpiderLabs
CVE: CVE-2015-4827

The "/user/add_item_to_comparison.cmd" page accept a parameter called
"dest" which accepts a path to any file within the the web server's root
directory.  This page does not properly sanitize "../" or "..\" and
therefore is susceptible to a LFI attack.  An unauthenticated attacker
could leverage this vulnerability in order to view files he/she should not
be able to see such as files in the "WEB-INF" directory.  Furthermore,
please note that it may be possible for an attacker to inject malicious
code into a file on the web server's file system, and, in combination with
this LFI vulnerability could force the application to execute malicious
code. This would allow the attacker to execute commands on the host
operating system in the context of the web application's user account.

The following Proof of Concept (PoC) requests the <web root>\WEB-INF\ocp-config.xml
which contains sensitive configuration information which is happily fulfilled by the application.
