Windows URI Handling Vulnerability - CVE-2007-3896

A remote code execution vulnerability exists in the way that the Windows shell handles specially crafted URIs that are passed to it. An attacker could exploit this vulnerability by including a specially crafted URI in an application or attachment, which could potentially allow remote code execution.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2007-3896.

Mitigating Factors for Windows URI Handling Vulnerability - CVE-2007-3896

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:

  • Windows 2000 Service Pack 4 is not affected
  • Windows Vista is not affected
  • Windows Vista x64 Edition is not affected
  • Microsoft has not identified a way to exploit this vulnerability on any Windows operating system that is running Internet Explorer 6
  • 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 an e-mail based attack of this exploit, customers who read e-mail in plain text are at less risk from this vulnerability. To be more at risk from this vulnerability, users would have to either click on a link that would take them to a malicious Web site or open an attachment.

Workarounds for Windows URI Handling Vulnerability - CVE-2007-3896

Microsoft has not identified any workarounds for this vulnerability.

FAQ for Windows URI Handling Vulnerability - CVE-2007-3896

What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged on user.

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 Windows shell insufficiently handles invalid URIs.

What is a URI?
A Uniform Resource Identifier (URI) is a string of characters used to act on or identify resources from the Internet or over a network. A URL is a typical example of a URI that references a resource such as a Web site. For more information about URIs, see RFC 2396.

What might an attacker use the vulnerability to do?
An attacker who has convinced a user to open an attachment in mail or to follow a link to an attacker's Web site could run arbitrary code as the logged on 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.

How could an attacker exploit the vulnerability?
An attacker would have to create a specially crafted URI and provide the URI as input to an application on an affected system, which would then attempt to access the resource referred to it by the URI. Applications that take URIs as input from untrusted sources such as attachments in e-mail, documents, or data from the network assuming it will be safe, are exposed to this vulnerability. Under specific circumstances, processing specially crafted URI input could allow arbitrary code to be executed. In order to exploit the vulnerability, an attacker would have to convince the user to launch the attachment or application, or visit the Web site. An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the Web site. This vulnerability might also be exploited by compromised Web sites or Web sites that accept or host user-provided content or advertisements. These Web sites could contain specially crafted URIs that could exploit this vulnerability. It could also be possible to display specially crafted URIs 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?
Systems running supported editions of Windows XP and Windows Server 2003 with Internet Explorer 7 installed are vulnerable.

What does the update do?
The update removes the vulnerability by changing the way that the Windows shell handles invalid URIs.

I do not have Windows Internet Explorer 7 installed. Why am I receiving this update?
The vulnerability exists in a Windows file, Shell32.dll, included in supported editions of Windows XP and Windows Server 2003. Microsoft has not identified any way to exploit this vulnerability on systems using Internet Explorer 6, which is the browser that is included with these operating systems. As a defense-in-depth measure, this security update is made available to all customers using supported editions of Windows XP and Windows Server 2003, regardless of which version of Internet Explorer is installed.

I am using Windows Vista, am I at risk from this vulnerability?
No. Windows Vista is not affected by this vulnerability. Windows Internet Explorer 7 is included with Windows Vista but the Windows shell in Windows Vista is not affected by this vulnerability.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability had been publicly disclosed when this security bulletin was originally issued. It has been assigned the Common Vulnerability and Exposure number CVE-2007-3896. This vulnerability was first described in Microsoft Security Advisory 943521.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
Yes. When the security bulletin was released, Microsoft had received information that this vulnerability was being exploited.

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 CVE-2007-3896.

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.

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.

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 many of 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.

    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.
