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.
