Microsoft Security Bulletin MS04-031 - Vulnerability in NetDDE Could Allow Remote Code Execution (841533). 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 that have full privileges. However, the NetDDE services are not started by default and would have to be manually started, or started by an application that requires NetDDE, for an attacker to attempt to remotely exploit this vulnerability.

However, this bulletin has a security update for this operating system version. Why is that?</b></p><p>The original version of Windows XP, commonly known as Windows XP Gold or Windows XP Release to Manufacturing (RTM) version, reached the end of its extended security update support life cycle on September 30, 2004. However, the end-of-life occurred very recently. In this case, the majority of the steps that are required to address this vulnerability were completed before this date. Therefore, we have decided to release a security update for this operating system version as part of this security bulletin. <br><br>We do not anticipate doing this for future vulnerabilities that may affect this operating system version, 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 this operating system version to migrate to supported operating system versions to prevent potential exposure to vulnerabilities.

</script><div class="expandoIndent"><p><b>What is the scope of the vulnerability?</b><br>This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could remotely take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges. However, the NetDDE services are not started by default and would have to be manually started for an attacker to attempt to remotely exploit this vulnerability. This vulnerability could also be used to attempt to perform a local elevation of privilege or remote denial of service.</p><p><b>What causes the vulnerability?</b><br>An unchecked buffer in the NetDDE services.</p><p><b>What is Network Dynamic Data Exchange?</b><br>Network Dynamic Data Exchange (NetDDE) allows two applications to communicate with each other over a network. This is considered an older communication method that typically has been replaced by newer technologies such as DCOM. For more information about DCOM, visit the <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndcom/html/msdn_dcomtec.asp">DCOM MSDN Web Site</a>.</p><p><b>What applications or services require NetDDE?</b><br>NetDDE is a considered to be an older network communication method. Applications such as the Windows for Workgroups 3.11 version of Microsoft Hearts (MSHearts) and Microsoft Chat (MSChat) application use NetDDE services. The version of Microsoft Hearts that is provided as part of Windows XP does not use NetDDE Services. The Clipbook service that is used to share a local clipboard to other systems in a network and the DDE Share Manager (DDEShare) application both require the NetDDE services. There are cases when Microsoft Excel could also use NetDDE. Microsoft Knowledge Base Article <a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;128491">128941</a> discusses how Microsoft Excel can use NetDDE. Third-party applications may also require the NetDDE services; therefore it is important to test the suggested workarounds in your organization before you deploy this update. </p><p><b>How can an administrator determine if NetDDE services are running?</b><br>Administrators can determine if the NetDDE services are running by viewing, Administrative Tools, Services, and searching for the NetDDE and the NetDDE DSDM services. The status of <b>Started</b> indicates that the services are running. See the Workarounds section of this security bulletin for instructions that explain how you can disable these services. </p><p><b>What might an attacker use the vulnerability to do?</b><br>An attacker who successfully exploited this vulnerability could take complete control of the affected system.</p><p><b>Who could exploit the vulnerability?</b><br>After the NetDDE services are started, any anonymous user who could deliver a specially crafted message to the affected system could attempt to remotely exploit this vulnerability. Operating systems other than Windows XP Service Pack2 and Windows Server 2003 have the NetDDE services set to a startup type of Manual instead of Disabled. This could allow non privileged users to start the NetDDE services or could allow them to start an application that starts the NetDDE services. After the NetDDE services are started, the affected system could be vulnerable to a remote attack. To help prevent this, see the Workaround section for instructions that explain how you can disable the NetDDE services. This vulnerability could also be used to attempt to perform a local elevation of privilege.</p><p><b>How could an attacker exploit the vulnerability?</b><br>After a NetDDE service is started, an attacker could exploit the vulnerability by creating a specially crafted message and sending the message to an affected system, which could then cause the affected system to remotely execute code. Receipt of such a message could also cause the vulnerable system to fail in such a way that it could cause a denial of service.</p><p>To exploit this vulnerability for a local elevation of privilege, an attacker would first have to log on to the system. An attacker could then run a specially-designed application that could attempt to exploit the vulnerability and thereby gain complete control over the affected system.</p><p>An attacker could also access the affected component through another vector. For example, an attacker could use another program that passes parameters to the vulnerable component (locally or remotely).</p><p><b>What systems are primarily at risk from the vulnerability?</b></p><p>Workstations and terminal servers are primarily at risk. Servers are only at risk if users are given the ability to log on and to run programs. However, best practices strongly discourage allowing this. </p><p>Windows XP Service Pack 2 is not vulnerable to this issue. Windows Server 2003 is impacted at a lower severity rating because the NetDDE services startup type is set to Disabled. An attacker would first have to change the setting from Disabled to Manual or Automatic, and then start the service to attempt to remotely exploit this vulnerability. Typically, only administrators can change the startup type of a service. Operating systems other than Windows Server 2003 have the NetDDE services set to a startup type of Manual instead of Disabled. This could allow non privileged users to start the NetDDE services or allow them to start an application that starts the NetDDE services. Once the NetDDE services are started the affected system could be vulnerable to a remote attack. To help prevent this, see the Workarounds section for instructions that explain how you can disable the NetDDE services.</p><p><b>Are Windows 98, Windows 98 Second Edition or Windows Millennium Edition critically affected by this vulnerability?</b><br>No. Although Windows 98, Windows 98 Second Edition, and Windows Millennium Edition do contain the affected component, the vulnerability is not critical because the NetDDE service is not started by default. For more information about severity ratings, visit the following <a href="http://go.microsoft.com/fwlink/?LinkId=21140">Web site</a>.</p><p><b>Could the vulnerability be exploited over the Internet? </b><br>Yes. If you have manually started the NetDDE services, or if you are using applications that may have started the NetDDE services, an attacker could attempt to remotely exploit this vulnerability over the Internet. Firewall best practices and standard default firewall configurations can help protect against attacks that originate from the Internet.

IT Professionals can visit the <a href="http://go.microsoft.com/fwlink/?LinkId=21171">Security Guidance Center Web site</a>.</p><p><b>What does the update do?</b><br>The update removes the vulnerability by modifying the way that the NetDDE services validate the length of a message before it passes the message to the allocated buffer.</p><p><b>When this security bulletin was issued, had this vulnerability been publicly disclosed?</b><br>No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information indicating that this vulnerability had been publicly disclosed when this security bulletin was originally issued.</p><p><b>When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?</b><br>No. Microsoft had not received any information indicating that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.</p></div><div style="margin-top: 3px; margin-bottom: 10px"><a href="#EAABUAA"><img width="7" height="9" border="0" src="/library/gallery/templates/MNP2.SecurityBulletin/../MNP2.Common/images/arrow_px_up.gif" alt="Top of section"></a><a class="topOfPage" href="#EAABUAA">Top of section</a></div></div></div><div style="margin-top: 3px; margin-bottom: 10px"><a href="#EABUAA"><img width="7" height="9" border="0" src="/library/gallery/templates/MNP2.SecurityBulletin/../MNP2.Common/images/arrow_px_up.gif" alt="Top of section"></a><a class="topOfPage" href="#EABUAA">Top of section</a></div></div></div><div style="margin-top: 3px; margin-bottom: 10px"><a href="#EBUAA"><img width="7" height="9" border="0" src="/library/gallery/templates/MNP2.SecurityBulletin/../MNP2.Common/images/arrow_px_up.gif" alt="Top of section"></a><a class="topOfPage" href="#EBUAA">Top of section</a></div></div><a name="EAUAA"></a><table cellspacing="0" cellpadding="0" border="0"><tr><td style="padding:6px 6px 0px 0px;"><script type="text/javascript" language="javascript">
