Cross-Site Scripting (XSS) Vulnerability in Netegrity IdentityMinder

Classification:
===============
Level: low-[MED]-high-crit
ID: HEXVIEW*2004*07*02*1

Overview:
=========
IdentityMinder is an identity and role management product developed by
Netegrity (http://www.netegrity.com), a microsoft gold-certified
identity and access management partner. Both primary and management web
interfaces are vulnerable to classic cross-site scripting (XSS) attacks.

Affected products:
==================
All tests were performed using Netegrity IdentityMinder Web Edition 5.6 SP2
for Windows, IIS Server, and Netegrity Policy Server V5.5. Possibly all other
IdentityMinder releases are vulnerable.

Cause and Effect:
=================
Although IdentityMinder product employs URL filtering capabilities that
disallow using common XSS characters in the URL, it is possible to
submit the URL string containing any character using zero-byte string
poisoning method. The part of the URL after %00 character is not checked
against XSS characters. Management interface is also vulnerable to XSS
and does not even require zero-byte poisoning.
The vulnerability makes possible to execute scripts in the context of webpage
with current IdentityMinder user privileges. It can be used to steal page data,
and/or to perform ItentityMinder tasks with the privileges of logged-in user.

Demonstration:
==============
The problem can be reproduced by entering following the link below (split over
several lines for readability). The example link is form action link from
ViewGroup search dialog. Please note that you need to replace PUT_*_HERE's
with your actual variables.

http://PUT_ADDRESS_HERE/idm/PUT_SITE_NAME_HERE/ims_mainconsole_principalpopuphandler.do?
searchAttrs0=%25GROUP_NAME%25&searchOperators0=EQUALS&searchFilter0=
&searchOrgDN=PUT_DN_HERE&incChildrenOrgFlag=NO&resultsPerPage=10&oid=
&imsui_taskstate=RESOLVE_SCOPE&imsui_tpnametosearch=group
&numOfExpressions=1%00<script>alert(document.cookie)</script>

Here is another link demonstrating the problem in IdentityMinder management
interface. Note that %00 poisoning is not required.
