Collaboration Data Objects Vulnerability - CAN-2005-1987

A remote code execution vulnerability exists in Collaboration Data Objects that could allow an attacker who successfully exploited this vulnerability to take complete control of the affected system.

Mitigating Factors for Collaboration Data Objects Vulnerability - CAN-2005-1987:

  • By default, Microsoft Internet Information Services (IIS) 5.0 Simple Mail Transfer Protocol (SMTP) and the Exchange 2000 Server SMTP service do not use the event sinks, which use the Cdosys.dll file and the Cdoex.dll file.
  • By default, IIS 6.0 is not enabled on Windows Server 2003.
  • IIS 6.0, when enabled, does not enable SMTP by default.

Workarounds for Collaboration Data Objects Vulnerability - CAN-2005-1987:

Microsoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.

  • Disable all event sinks that are enabled on Exchange 2000 Server and on servers that are running IIS:

    Disabling all event sinks will help protect the affected system from attempts to exploit this vulnerability. To disable the any custom or third-party event sinks, follow these steps:

    1. Use the cscript.exe smtpreg.vbs /enum command-line command to enumerate all the registered event sinks. Examine the output of this command and look for custom or non-Microsoft software event sink entries.
    2. After you identify the event sink that you want to disable, run the following command at a command prompt:

      cscript.exe smtpreg.vbs /disable

    Impact of Workaround: The custom or third-party application that has created the event sink in the SMTP service will not work correctly until the event sink is re-enabled.

  • Unregister the Cdoex.dll file and the Cdosys.dll file on Exchange 2000 Server and unregister the Cdosys.dll file on servers that are running IIS:

    Unregistering the Cdoex.dll file and the Cdosys.dll file helps protect the affected system from attempts to exploit this vulnerability.

    To disable the Cdoex.dll file and the Cdosys.dll file for Exchange 2000 Server, follow these steps.

    Important You must follow these steps in the following order.

    1. Run the following command at a command prompt:

      Regsvr32.exe “C:\Program Files\Common Files\Microsoft Shared\CDO\cdoex.dll” /u
    2. Run the following command at a command prompt:

      Regsvr32.exe %windir%\system32\cdosys.dll /u

    To disable the Cdosys.dll file for servers that are running IIS, type the following command at a command prompt:

    1. Regsvr32.exe %windir%\system32\cdosys.dll /u

    Impact of Workaround: Unregistering COM objects breaks programs that depend on the Cdosys.dll file or the Cdoex.dll file.

Notes When you install these security updates, 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.

If you have previously installed a hotfix to update one of these files, the installer copies the RTMQFE, SP1QFE, or SP2QFE files to your system. Otherwise, the installer copies the RTMGDR, SP1GDR, or SP2GDR files to your system. Security updates may not contain all variations of these files. For more information about this behavior, see Microsoft Knowledge Base Article 824994.

For more information about the Update.exe installer, visit the Microsoft TechNet Web site.

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

Arpidfix.exe is used by the security update installer to address an issue documented in Microsoft Knowledge Base Article 904630. This file is not installed onto the affected system.

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. MBSA 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.

  • 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 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 following registry keys.

    For Windows XP Home Edition Service Pack 1, Windows XP Professional Service Pack 1, Windows XP Tablet PC Edition, Windows XP Media Center Edition, Windows XP Home Edition Service Pack 2, Windows XP Professional Service Pack 2, Windows XP Tablet PC Edition 2005, and Windows XP Media Center Edition 2005:
