A remote code execution vulnerability exists in the way that the VBScript and JScript scripting engines decode script in Web pages. This vulnerability could allow remote code execution if a user opened a specially crafted file or visited a Web site that is running specially crafted script. If a user is logged on with administrative user rights, 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-0083.

Mitigating Factors for VBScript/JScript Remote Code Execution Vulnerability - CVE-2008-0083

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:

  • An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  • In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker’s Web site.
  • In an e-mail-based attack of this exploit, customers who read e-mail in plain text are at less risk from this vulnerability.
  • By default, all supported versions of Microsoft Outlook and Microsoft Outlook Express open HTML e-mail messages in the Restricted sites zone. The Restricted sites zone helps reduce attacks that could try to exploit this vulnerability, by preventing Active Scripting and ActiveX controls from being used when reading HTML e-mail. However, if a user clicks on a link within an e-mail they could still be vulnerable to this issue through the Web-based attack scenario.
  • Systems with Internet Explorer 7, which is delivered with VBScript.dll version 5.7 and JScript.dll version 5.7, are not affected by this vulnerability.
  • By default, Internet Explorer on Windows Server 2003 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that have not been added to Internet Explorer Trusted sites zone. See the FAQ subsection of this vulnerability section for more information about Internet Explorer Enhanced Security Configuration.

Workarounds for VBScript/JScript Remote Code Execution Vulnerability - CVE-2008-0083

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:

  • Unregister the VBScript.Encode and JScript.Encode COM objects.

    Warning Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use 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.
    • Using the interactive method:
      1. Click Start, click Run, type regedit, and then click OK.
      2. Expand HKEY_CLASSES_ROOT.
      3. Click VBScript.Encode.
      4. Click File and select Export.
      5. In the Export Registry File dialog, type vbscript_encode_configuration_backup.reg 
        and click Save.
      6. Press Delete.
      7. Click OK.
      8. Repeat steps 3 through 7 for JScript.Encode.
      9. Close any open instances of Internet Explorer.
    • Using a managed deployment script:
      1. Create a backup copy of the registry keys using a managed deployment script containing the following commands:

        regedit /e vbscript_encode_configuration_backup.reg
        HKEY_CLASSES_ROOT\VBScript.Encode

        regedit /e jscript_encode_configuration_backup.reg
        HKEY_CLASSES_ROOT\JScript.Encode
      2. Next save the following to a file with a .REG extension, for example, Disable_vbscript_and_jscript_encode.reg:

        Windows Registry Editor Version 5.00
        [-HKEY_CLASSES_ROOT\VBScript.Encode]
        [-HKEY_CLASSES_ROOT\JScript.Encode]
      3. Run the registry script created in step 2 on the target machine with the following command:

        Regedit /s Disable_vbscript_and_jscript_encode.reg

    Impact of workaround. Encoded scripts will not work but regular scripts will continue working.

    How to undo the workaround.

  • Using the interactive method:
    1. Click Start, click Run, type regedit, and then click OK.
    2. Click File and select Import.
    3. In the Import Registry File dialog, select 
      vbscript_encode_configuration_backup.reg 
      and click Open.
    4. Click File and select Import.
    5. In the Import Registry File dialog, select 
      jscript_encode_configuration_backup.reg 
      and click Open.
  • Using a managed deployment script:
    • Restore the original state by running the following commands:

      Regedit /s vbscript_encode_configuration_backup.reg
      Regedit /s jscript_encode_configuration_backup.reg

FAQ for VBScript/JScript Remote Code Execution Vulnerability - CVE-2008-0083

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. If a user is logged on with administrative user rights, 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

What causes the vulnerability? 
The vulnerability is caused by the way that the VBScript and JScript scripting engines decode scripts in Web pages to allow the scripts to load into memory in order to run.

What is script decoding? 
Web designers use scripting on Web pages and server-side active server pages (.ASP) to add features to Web pages. Web designers also encode these scripts to make it difficult for users to read the script embedded in the page, or to copy it and adapt it to their own purposes. When the script needs to run, the scripting engine decodes the script in order to load the script to memory.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. 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 host a specially crafted Web site that is designed to exploit this vulnerability and then convince a user to visit the Web site. This could also include compromised Web sites and Web sites that accept or host user-provided content or advertisements. These Web sites could contain specially crafted content that could exploit these vulnerabilities. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger message that takes users to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.

What systems are primarily at risk from the vulnerability? 
Client or workstation systems where Internet Explorer is used to browse Web pages and where VBScript.dll and JScript.dll versions below 5.6.0.8835 are used, are primarily at risk.

I am running Internet Explorer on Windows Server 2003. Does this mitigate this vulnerability? 
Yes. By default, Internet Explorer on Windows Server 2003 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that have not been added to Internet Explorer Trusted sites zone.

What is the Internet Explorer Enhanced Security Configuration? 
Internet Explorer Enhanced Security Configuration is a group of preconfigured Internet Explorer settings that reduce the likelihood of a user or of an administrator downloading and running specially crafted Web content on a server. Internet Explorer Enhanced Security Configuration reduces this risk by modifying many security-related settings. This includes the settings on the Security tab and the Advanced tab in the Internet Options dialog box. Some of the important modifications include the following:

  • Security level for the Internet zone is set to High. This setting disables scripts, ActiveX controls, Microsoft Java Virtual Machine (MSJVM), and file downloads.
  • Automatic detection of intranet sites is disabled. This setting assigns all intranet Web sites and all Universal Naming Convention (UNC) paths that are not explicitly listed in the Local intranet zone to the Internet zone.
  • Install On Demand and non-Microsoft browser extensions are disabled. This setting prevents Web pages from automatically installing components and prevents non-Microsoft extensions from running.
  • Multimedia content is disabled. This setting prevents music, animations, and video clips from running.

For more information regarding Internet Explorer Enhanced Security Configuration, see the guide, Managing Internet Explorer Enhanced Security Configuration.

What does the update do? 
This security update addresses the vulnerability by modifying the way that the VBScript and JScript engines decode script in Web pages. The VBScript scripting engine is named VBScript.dll; the JScript scripting engine is named JScript.dll.

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.

/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 Displays 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.

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 editions of Microsoft Windows, the following steps may be different on your system. 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 edition of the operating system, or the programs that are installed on your system, 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 system 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.

    These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.

Deployment Information

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.

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 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.
