Issue:
======
Microsoft Content Management Server (MCMS) 2001 is an Enterprise
Server product that simplifies developing and managing E-Commerce
web sites. MCMS includes a number of pre-defined ASP web pages that
allow web site operators to quickly set up E-business websites.

A Cross-Site Scripting flaw exists in one of these ASP pages that
could allow an attacker to insert script into the data being sent
to a MCMS server. Because the server generates a web page in
response to a user request made using this page, it is possible that
the script could be embedded within the page that CMS generates and
returns to the user, this script would then run when processed by
the user's browser. This could result in an attacker being able to
access information the user shared with the legitimate site.

An attacker might attempt to exploit this flaw by crafting a
malicious link to a valid site that the user intended to visit.
If the attacker were able to get a user to click the link-most
likely by sending the link in an email-then it could be possible
for the attacker to take a variety of actions. The attacker could
alter the data that appeared to be contained on the web pages
presented by the legitimate site, monitor the user's session with
the legitimate site and copy personal data from the legitimate site
to a site under the attacker's control, or access the legitimate
site's cookies.

Mitigating Factors:
====================
- This flaw is not present in Microsoft Content Management
  Server 2002.
- The attacker would have no way to force users to visit
  the malicious site. Instead, the attacker would need to
  lure them there, typically by getting them to click on
  a link that would take them to the attacker's site.

Risk Rating:
============
- Moderate

Patch Availability:
===================
