General Information

Executive Summary

Executive Summary:

This update resolves a newly-discovered, publicly reported vulnerability. 
A remote code execution vulnerability exists in the way that the Windows 
Shell launches applications.

If a user is logged on with administrative privileges, an attacker who 
successfully exploited this vulnerability could take complete control of 
an affected system, including installing programs; viewing, changing, or 
deleting data; or creating new accounts with full privileges. However, 
significant user interaction is required to exploit this vulnerability. 
Users whose accounts are configured to have fewer privileges on the system 
would be at less risk than users who operate with administrative 
privileges.

We recommend that customers consider applying the security update.

Frequently asked questions (FAQ) related to this security update

I'm still using Microsoft Windows NT 4.0 Workstation Service Pack 6a or 
Windows 2000 Service Pack 2, but extended security update support ended on 
June 30, 2004. However, this bulletin has a security update for these 
operating system versions. Why is that?
Windows NT 4.0 Workstation Service Pack 6a and Windows 2000 Service Pack 2 
have reached the end of their life cycles as previously documented, and 
Microsoft extended this support to June 30, 2004. However, the end-of-life 
for the extended support period occurred very recently. In this case, the 
majority of the steps that are required to address this vulnerability were 
completed before June 30, 2004. Therefore, we have decided to release 
security updates for these operating system versions as part of this 
security bulletin. We do not anticipate doing this for future 
vulnerabilities affecting these operating system versions, but we reserve 
the right to produce updates and to make these updates available when 
necessary.

It should be a priority for customers who have these operating system 
versions to migrate to supported versions to prevent potential exposure to 
future vulnerabilities. For more information about the Windows Product 
Life Cycle, visit the following Microsoft Support Lifecycle Web site. For 
more information about the extended security update support period for 
these operating system versions, visit the following Microsoft Product 
Support Services Web site.

Customers who require additional support for Windows NT Workstation 4.0 
SP6a must contact their Microsoft account team representative, their 
Technical Account Manager, or the appropriate Microsoft partner 
representative for custom support options. Customers without an Alliance, 
Premier, or Authorized Contract can contact their local Microsoft sales 
office. For contact information, visit the Microsoft Worldwide Information 
Web site, select the country, and then click Go to see a list of phone 
numbers. When you call, ask to speak with the local Premier Support sales 
manager.

For more information, see the Windows Operating System FAQ.

What updates does this release replace?
This security update replaces several prior security bulletins. The 
security bulletin IDs and operating systems that are affected are listed 
in the table below.

Does this update contain any other changes to functionality?
Yes. In addition to the changes that are listed in the Vulnerability 
Details section of this bulletin, this update includes the following 
changes in functionality:


This update refines a change made in Internet Explorer 6 Service Pack 1, 
which prevents Web pages that are loaded while a user is in the Internet 
zone from navigating to the Local Machine zone. This change was introduced 
to mitigate the effects of potential new cross domain vulnerabilities. The 
changes introduced in this update are additional enhancements of the 
Internet Explorer 6 Service Pack 1 restrictions.


Microsoft has also made another defense in depth change which limits the 
functionality of the Shell Automation Service ActiveX control 
(shell.application). This feature has been modified to provide greater 
security and to prevent potential malicious use. Microsoft considers this 
to be a defense in depth measure that we are taking to provide additional 
protection against malicious use.

How does the extended support for Windows 98, Windows 98 Second Edition, 
and Windows Millennium Edition affect the release of security updates for 
these operating systems?
Microsoft will only release security updates for critical security issues. 
Non-critical security issues are not offered during this support period. 
For more information about the Microsoft Support Lifecycle policies for 
these operating systems, visit the following Web site.

For more information about severity ratings, visit the following Web site.

Are Windows 98, Windows 98 Second Edition, or Windows Millennium Edition 
critically affected by any of the vulnerabilities that are addressed in 
this security bulletin?
No. None of these vulnerabilities are critical in severity on Windows 98, 
on Windows 98 Second Edition, or on Windows Millennium Edition.

Can I use the Microsoft Baseline Security Analyzer (MBSA) to determine if 
this update is required?
MBSA will determine if this update is required for Windows 2000 (all 
versions), Windows XP (all versions), and Windows 2003 (all versions). 
MBSA does not currently support the full detection of this update for the 
Windows NT 4.0 product (all versions). For more information about MBSA, 
visit the MBSA Web site.

Note After April 20, 2004, the Mssecure.xml file that is used by MBSA 
1.1.1 and earlier versions is no longer being updated with new security 
bulletin data. Therefore, scans that are performed after that date with 
MBSA 1.1.1 or earlier will be incomplete. All users should upgrade to MBSA 
1.2 because it provides more accurate security update detection and 
supports additional products. Users can download MBSA 1.2 from the MBSA 
Web site. For more information about MBSA support, visit the following 
Microsoft Baseline Security Analyzer 1.2 Q&A Web site.

Can I use Systems Management Server (SMS) to determine if this update is 
required?
SMS uses MBSA for detection. SMS can help detect and deploy this security 
update for Windows 2000 (all versions), Windows XP (all versions), and 
Windows 2003 (all versions). This update is not detected by MBSA for the 
Windows NT 4.0 product (all versions). However, the file and registry key 
information that is available in this bulletin can be used to write 
specific file and registry key collection queries in SMS to detect 
vulnerable computers. For information about how to deploy updates not 
supported by MBSA with SMS, please review Knowledge Base article 867832. 
For information about SMS, visit the SMS Web site.

What component installs the Shell-Integrated Browser (Active Desktop) on 
my Windows NT 4.0 system?
Microsoft Internet Explorer 4.0 can install this component. If you have 
Internet Explorer 4.0 installed on your system, you might have the 
Shell-Integrated Browser.

How do I know if I have Active Desktop installed on my Windows NT 4.0 
system?
Microsoft Knowledgebase Article 216840 contains information on how to 
determine if you have Active Desktop installed on your system.

Why is there no update available for Microsoft Windows NT Server 4.0 
Terminal Server Edition with Active Desktop?
Active Desktop is not supported on Microsoft Windows NT Server 4.0 
Terminal Server Edition. For more information see Microsoft Knowledge Base 
Article 186498.

Vulnerability Details

Windows Shell Vulnerability - CAN-2004-0420:

A remote code execution vulnerability exists in the way that the Windows 
Shell launches applications. An attacker could exploit the vulnerability 
if a user visited a malicious Web site. If a user is logged on with 
administrative privileges, an attacker who successfully exploited this 
vulnerability could take complete control of an affected system. However, 
user interaction is required to exploit this vulnerability.

Mitigating Factors for Windows Shell Vulnerability - CAN-2004-0420:


In a Web-based attack scenario, an attacker would have to host a Web site 
that contains a Web page that is used to exploit this vulnerability. An 
attacker would have no way to force users to visit a malicious Web site. 
Instead, an attacker would have to persuade them to visit the Web site, 
typically by getting them to click a link that takes them to the 
attacker's site.


An attacker who successfully exploited this vulnerability could gain the 
same privileges as the user. Users whose accounts are configured to have 
fewer privileges on the system would be at less risk than users who 
operate with administrative privileges.

FAQ for Windows Shell Vulnerability - CAN-2004-0420:

What is the scope of the vulnerability?
This is remote code execution vulnerability. If a user is logged on with 
administrative privileges, an attacker who successfully exploited this 
vulnerability could take complete control of an affected system, including 
installing programs; viewing, changing, or deleting data; or creating new 
accounts with full privileges. However, user interaction is required to 
exploit this vulnerability. Users whose accounts are configured to have 
fewer privileges on the system would be at less risk than users who 
operate with administrative privileges.

What causes the vulnerability?
The Windows Shell application programming interface (API) supports the 
ability to associate a class identifier (CLSID) with a file type. An 
attacker could use a CLSID instead of the valid extension for a file type 
that could help persuade a user to run a malicious program.

What is Windows Shell application programming interface?
Windows Shell APIs are the programming interfaces that support extensions 
of the system~Rs operational environment. For more information about the 
Windows Shell application programming interface, visit the following Web 
site.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could gain the 
same privileges as the user. Users whose accounts are configured to have 
fewer privileges on the system would be at less risk than users who 
operate with administrative privileges.

How could an attacker exploit the vulnerability?
To exploit this vulnerability, an attacker would have to host a malicious 
Web site and then persuade a user to view that Web site. An attacker could 
also create an HTML e-mail message that has a specially crafted link, and 
then persuade a user to view the HTML e-mail message and then click the 
malicious link.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers are only 
at risk if users who do not have sufficient administrative credentials are 
given the ability to log on to servers and to run programs. However, best 
practices strongly discourage allowing this.

Are Windows 98, Windows 98 Second Edition or Windows Millennium Edition 
critically affected by this vulnerability?
No. Although Windows Millennium Edition does contain the affected 
component, the vulnerability is not critical. For more information about 
severity ratings, visit the following Web site.

What does the update do?
The update removes the ability to use a CLSID as a file type within 
Windows Shell.

When this security bulletin was issued, had this vulnerability been 
publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned 
Common Vulnerability and Exposure number CAN-2004-0420.

When this security bulletin was issued, had Microsoft received any reports 
that this vulnerability was being exploited?
No. Microsoft had seen examples of proof of concept code published 
publicly but had not received any information indicating that this 
vulnerability had been publicly used to attack customers when this 
security bulletin was originally issued.

Does applying this security update help protect customers from the code 
that has been published publicly that attempts to exploit this 
vulnerability?
Yes. This security update addresses the vulnerability that is currently 
being exploited. The vulnerability that has been addressed has been 
assigned the Common Vulnerability and Exposure number CAN-2004-0420.

Are there any other steps I should take in addition to applying this patch 
to help protect my computer?
Yes. In addition to applying this security update, it is recommended that 
users also install the ADODB.stream update that is referenced in Knowledge 
Base Article 870669. This update is available from Windows Update and from 
the Microsoft Download Center for all supported versions of Windows. While 
not a security patch, this update contains a change to the behavior of a 
Data Access component in Windows to help protect against attacks that are 
made by using Internet Explorer.

Specifically, it disables the ability for the ADODB.Stream object ability 
to function within Internet Explorer.

may not be installed.

5.


On the Version tab, determine the version of the file that is installed on 
your computer by comparing it to the version that is documented in the 
appropriate file information table.

Note Attributes other than file version may change during installation. 
Comparing other file attributes to the information in the file information 
table is not a supported method of verifying the update installation. 
Also, in certain cases, files may be renamed during installation. If the 
file or version information is not present, use one of the other available 
methods to verify update installation.


Registry Key Verification

You may also be able to verify the files that this security update has 
installed by reviewing the following registry keys.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows Server 
2003\SP1\KB839645\Filelist

Notes The Windows XP and Windows XP 64-Bit Edition Version 2003 versions 
of this security update are packaged as dual-mode packages, which contain 
files for both the original version of Windows XP and Windows XP Service 
Pack 1 (SP1). For more information about dual-mode packages, see Microsoft 
Knowledge Base Article 328848.

When you install the Windows XP 64-Bit Edition Version 2003 security 
update, the installer checks to see if any of the files that are being 
updated on your system have previously been updated by a Microsoft hotfix. 
If you have previously installed a hotfix to update one of these files, 
the installer copies the RTMQFE files to your system. Otherwise, the 
installer copies the RTMGDR files to your system. For more information, 
see Microsoft Knowledge Base Article 824994.

Verifying Update Installation


Microsoft Baseline Security Analyzer

To verify that a security update is installed on an affected system, you 
may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. 
This tool allows administrators to scan local and remote systems for 
missing security updates and for common security misconfigurations. For 
more information about MBSA, visit the Microsoft Baseline Security 
Analyzer Web site.

Verifying Update Installation


File Version Verification

Note Because there are several versions of Microsoft Windows, the 
following steps may be different on your computer. If they are, see your 
product documentation to complete these steps.

1.


Click Start, and then click Search.

2.


In the Search Results pane, click All files and folders under Search 
Companion.

3.


In the All or part of the file name box, type a file name from the 
appropriate file information table, and then click Search.

4.


In the list of files, right-click a file name from the appropriate file 
information table, and then click Properties.

Note Depending on the version of the operating system or programs 
installed, some of the files that are listed in the file information table 
may not be installed.

5.


On the Version tab, determine the version of the file that is installed on 
your computer by comparing it to the version that is documented in the 
appropriate file information table.

Note Attributes other than file version may change during installation. 
Comparing other file attributes to the information in the file information 
table is not a supported method of verifying the update installation. 
Also, in certain cases, files may be renamed during installation. If the 
file or version information is not present, use one of the other available 
methods to verify update installation.


Registry Key Verification

You may also be able to verify the files that this security update has 
installed by reviewing the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed 
Components\{7ac88637-e78a-4036-a333-f65808b791bc}

Note Confirm that the IsInstalled DWORD value with a data value of 1 
appears in the registry key.


Program Version Verification

Office Update

Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can 
quickly and reliably deploy the latest critical updates and security 
updates to Windows 2000 and Windows Server 2003-based servers, and to 
desktop systems that are running Windows 2000 Professional or Windows XP 
Professional.

For more information about how to deploy this security update with 
Software Update Services, visit the Software Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly-configurable 
enterprise solution for managing updates. By using SMS, administrators can 
identify Windows-based systems that require security updates and to 
perform controlled deployment of these updates throughout the enterprise 
with minimal disruption to end users. For more information about how 
administrators can use SMS 2003 to deploy security updates, see the SMS 
2003 Security Patch Management Web site. SMS 2.0 users can also use 
Software Updates Service Feature Pack to help deploy security updates. For 
information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft 
Office Detection Tool to provide broad support for security bulletin 
update detection and deployment. Some software updates may not be detected 
by these tools. Administrators can use the inventory capabilities of the 
SMS in these cases to target updates to specific systems. For more 
information about this procedure, see the following Web site. Some 
security updates require administrative rights following a restart of the 
system. Administrators can use the Elevated Rights Deployment Tool 
(available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 
Administration Feature Pack) to install these updates.
