Windows Kernel TCP/IP/IGMPv3 and MLDv2 Vulnerability - CVE-2007-0069

A remote code execution vulnerability exists in the Windows kernel due to the way that the Windows kernel handles TCP/IP structures storing the state of IGMPv3 and MLDv2 queries. Supported editions of Microsoft Windows XP, Windows Server 2003, and Windows Vista all support IGMPv3. In addition to IGMPv3, Windows Vista supports MDLv2, which adds multicast support for IPv6 networks. An anonymous attacker could exploit the vulnerability by sending specially crafted IGMPv3 and MLDv2 packets to a computer over the network. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2007-0069.

Mitigating Factors for Windows Kernel TCP/IP/IGMPv3 and MLDv2 Vulnerability - CVE-2007-0069

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed. Perimeter firewalls that block multicast traffic (IGMPv3 and MLDv2 specifically) help protect internal network assets from this attack that originate outside of the enterprise perimeter.
  • Microsoft Windows 2000 is not affected by this vulnerability.
  • Windows Server 2003 by default does not have any multicast addresses active and would not be affected by this vulnerability. However, installing applications that use multicasting could cause the operating system to become vulnerable.
  • Attacks attempting to exploit this vulnerability would most likely result in a denial of service condition. However remote code execution could be possible.

Workarounds for Windows Kernel TCP/IP/IGMPv3 and MLDv2 Vulnerability - CVE-2007-0069

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality.

  • Disable IGMP and MLD processing

    You can help prevent attempts to exploit the IGMP vulnerability by modifying the IGMPLevel control in the registry.

    Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use the Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.

    Note We recommend backing up the registry before you edit it.

    To disable IGMP and MLD processing, following these steps:

    1. Click Start, click Run, type regedit and then click OK.
    2. Expand HKEY_LOCAL_MACHINE.
    3. Expand SYSTEM, expand CurrentControlSet, and then expand Services.
    4. Expand TCPIP, expand Parameters, and then expand IGMPLevel.
    5. Change the DWORD value to 0.

    Note You must restart the system for your changes to take effect.

    Impact of workaround: IGMPv3 and MLDv2 will be disabled. Applications that depend on this service will no longer function as designed.

    How to undo the workaround: Use the steps above to set the registry key setting to its original value or delete this registry key setting. By default this registry key setting is not present.

  • Block IGMP and MLD on perimeter firewalls

    Firewall best practices and standard default firewall configurations can help protect networks from IGMP and MLD attacks that originate outside the enterprise perimeter.

    Impact of workaround: IGMPv3 and MLDv2 will be blocked from outside the enterprise perimeter, and applications that depend on IGMPv3 and MLDv2 from outside the enterprise perimeter will no longer function as designed.

  • Block IGMP and MLD inbound on Vista Firewall

    Click Control Panel, click Administrative Tools, and then double-click Windows Firewall with Advanced Security.

    To Block IGMP:

    1. Select inbound rules.
    2. Select Core Networking - Internet Group Management Protocol (IGMP-In).
    3. Right-click select properties.
    4. Select Block the connections.

    To Block MLD:

    1. Select inbound rules.
    2. Select Core Networking - Multicast Listener Query (ICMPv6-In).
    3. Right-click select properties.
    4. Select Block the connections.
  • Impact of workaround: IGMP/MLD will be blocked and applications or services that rely on multicast will no longer function.

    How to undo the workaround: Use the first three steps above and select Allow the connections.

FAQ for Windows Kernel TCP/IP/IGMPv3 and MLDv2 Vulnerability - CVE-2007-0069

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated privileges on vulnerable systems. An attacker could then install programs or view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability? 
The Windows kernel performs insufficient validation when storing the state of IGMP requests processed by TCP/IP.

What is TCP/IP?
TCP/IP is the suite of communications protocols used for transmitting data over networks.

Why is the vulnerability rating different for Windows Small Business Server and Windows Home Server than Windows Server 2003?
Windows Server 2003 by default does not have IGMP active and therefore is less exposed to this vulnerability. However, Windows Small Business Server 2003 and Windows Home Server have IGMP active by default, resulting in an increased risk to this vulnerability. The increased risk merits a severity rating of Critical for Windows Small Business Server 2003 and Windows Home Server. We recommend that customers with these products install this update immediately.

What is IGMP?
Internet Group Management Protocol (IGMP) is used for IPv4 multicast. A multicast is communication between a single sender and multiple receivers on a network. IGMP is used to exchange membership status data between IPv4 routers that support multicasting and members of multicast groups. See the MSDN site for more information on IGMP.

What is MLD?
Multicast Listener Discovery (MLD) enables you to manage subnet multicast membership for IPv6. MLD is a series of three Internet Control Message Protocols for IPv6 (ICMPv6) messages that replaces the Internet Group Management Protocol (IGMP) that is used for IPv4. See the MSDN site for more information on MLD.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could run arbitrary code. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

How could an attacker exploit the vulnerability? 
An attacker could try to exploit the vulnerability by creating specially crafted network packets and sending the packets to an affected system.

What systems are primarily at risk from the vulnerability? 
Client systems are primarily at risk from this vulnerability. However, any systems that use multicasting could be affected by this vulnerability.

What does the update do? 
The update removes the vulnerability by modifying the way that the Windows kernel processes TCP/IP structures that contain IGMP requests.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued. This security bulletin addresses the privately disclosed vulnerability as well as additional issues discovered through internal investigations.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? 
No. Microsoft had not received any information to indicate 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.

Windows Kernel TCP/IP/ICMP Vulnerability - CVE-2007-0066

A denial of service vulnerability exists in TCP/IP due to the way that Windows Kernel processes fragmented router advertisement ICMP queries. ICMP Router Discovery Protocol (RDP) is not enabled by default and is required in order to exploit this vulnerability. However, on Windows 2003 Server and on Windows XP, RDP can be turned on by a setting in DHCP or by a setting in the registry. On Windows 2000, RDP can be turned on by a setting in the registry. An anonymous attacker could exploit the vulnerability by sending specially crafted ICMP packets to a computer over the network. An attacker who successfully exploited this vulnerability could cause the computer to stop responding and automatically restart.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2007-0066.

Mitigating Factors for Windows Kernel TCP/IP/ICMP Vulnerability - CVE-2007-0066

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • Router Discovery Protocol (RDP) is not enabled by default and is required in order to exploit this vulnerability. For more information, see Microsoft Knowledge Base Article 269734, “Router Discovery Protocol Is Disabled by Default.”

Workarounds for Windows Kernel TCP/IP/ICMP Vulnerability - CVE-2007-0066

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality.

  • Disable Router Discovery Protocol Processing

    By default, Router Discovery Protocol is disabled on all affected platforms. If the Router Discovery Protocol is already enabled, the following workaround would disable it. You can help prevent attempts to exploit the ICMP vulnerability by setting the PerformRouterDiscovery value in the registry.

    Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use the Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.

    Note We recommend backing up the registry before you edit it.

    To disable ICMP processing, following these steps:

    1. Click Start, click Run, type regedit and then click OK.
    2. Expand HKEY_LOCAL_MACHINE.
    3. Expand SYSTEM, expand CurrentControlSet, and then expand Services.
    4. Expand TCPIP, expand Parameters, and then expand Interfaces.
    5. Select interface_name and set the PerformRouterDiscovery value to 0.

    Note You must restart the system for your changes to take effect.

    Impact of workaround: Router Discovery will be disabled.

Installing the Update

When you install this security update, the installer checks to see if one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.

For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.

This security update supports the following setup switches. This security update supports the following setup switches.

Switch Description
/help Displays the command-line options
Setup Modes
/passive Unattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the computer will restart in 30 seconds.
/quiet Quiet mode. This is the same as unattended mode, but no status or error messages are displayed.
Restart Options
/norestart Does not restart when installation has completed
/forcerestart Restarts the computer after installation and force other applications to close at shutdown without saving open files first.
/warnrestart[:x] Presents a dialog box with a timer warning the user that the computer will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch.
/promptrestart Display a dialog box prompting the local user to allow a restart
Special Options
/overwriteoem Overwrites OEM files without prompting
/nobackup Does not back up files needed for uninstall
/forceappsclose Forces other programs to close when the computer shuts down
/log:path Allows the redirection of installation log files
/integrate:path Integrates the update into the Windows source files. These files are located at the path that is specified in the switch.
/extract[:path] Extracts files without starting the Setup program
/ER Enables extended error reporting
/verbose Enables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly.

Note You can combine these switches into one command. For backward compatibility, the security update also supports the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841. For more information about the Update.exe installer, visit the Microsoft TechNet Web site.

Verifying That the Update Has Been Applied

  • Microsoft Baseline Security Analyzer

    To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information

  • File Version Verification

    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 the 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 that the update has been applied. 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 registry keys listed in the Reference Table in this section.

Installing the Update

When you install this security update, the installer checks to see if one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.

This security update supports the following setup switches.

Switch Description
/?, /h, /help Displays help on supported switches.
/quiet Suppresses the display of status or error messages.
/norestart When combined with /quiet, the system will not be restarted after installation even if a restart is required to complete installation.

Note For more information about the wusa.exe installer, see Microsoft Knowledge Base Article 934307.

Verifying that the Update Has Been Applied

  • Microsoft Baseline Security Analyzer

    To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information

  • File Version Verification

    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 the 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 that the update has been applied. 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.
