Shortcut Icon Loading Vulnerability - CVE-2010-2568
A remote code execution vulnerability exists in affected versions of Microsoft Windows. The vulnerability exists because Windows incorrectly parses shortcuts in such a way that malicious code may be executed when the operating system displays the icon of a malicious shortcut file. An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. This update addresses a vulnerability previously discussed in Microsoft Security Advisory 2286198.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-2568.
Mitigating Factors for Shortcut Icon Loading Vulnerability - CVE-2010-2568
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 exploits 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.
- For the USB removable device attack vector, when AutoPlay is disabled, the user would manually have to launch Windows Explorer or a similar application and browse to the affected folder of the removable disk.
Workarounds for Shortcut Icon Loading Vulnerability - CVE-2010-2568
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 the displaying of icons for shortcuts
Note See Microsoft Knowledge Base Article 2286198 to use the automated Microsoft Fix it solution to enable or disable this workaround. This Fix it solution requires a restart upon completion in order to be effective. This Fix it solution deploys the workaround, and thus has the same user impact. We recommend that administrators review the KB article closely prior to deploying this Fix it solution.
Note 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.
- Click Start, click Run, type Regedit in the Open box, and then click OK.
- Locate and then select the following registry key:
HKEY_CLASSES_ROOT\lnkfile\shellex\IconHandler - Click the File menu and then click Export.
- In the Export Registry File dialog box, enter LNK_Icon_Backup.reg and then click Save.
Note This will create a backup of this registry key in the My Documents folder by default. - Select the value (Default) on the right pane in the Registry Editor. Press Enter to edit the value of the key. Delete the value, so that the value is blank, and press Enter.
- Locate and then select the following registry key:
HKEY_CLASSES_ROOT\piffile\shellex\IconHandler - Click the File menu and then click Export.
- In the Export Registry File dialog box, enter PIF_Icon_Backup.reg and then click Save.
Note This creates a backup of this registry key in the My Documents folder by default. - Select the value (Default) on the right pane in the Registry Editor. Press Enter to edit the value of the key. Delete the value, so that the value is blank, and press Enter.
- Log all users off and on again, or restart the computer.
Impact of workaround. Disabling icons from being displayed for shortcuts prevents the issue from being exploited on affected systems. When this workaround is implemented, the system may display most icons as a "white" default object icon, which does impact usability. We recommend that system administrators test this workaround thoroughly prior to deployment. When the workaround is undone, all icons will reappear.
How to undo the workaround.
Using the interactive method
- Click Start, click Run, type Regedit in the Open box, and then click OK.
- Click the File menu and then click Import.
- In the Import Registry File dialog box, select LNK_Icon_Backup.reg, and then click Open.
- Click the File menu and then click Import.
- In the Import Registry File dialog box, select PIF_Icon_Backup.reg, and then click Open.
- Exit Registry Editor, and then restart the computer.
Manually resetting the Registry key values to the default values
- Click Start, click Run, type Regedit in the Open box, and then click OK.
- Locate and then click the following registry key:
HKEY_CLASSES_ROOT\lnkfile\shellex\IconHandler - Reset the registry key value to:
{00021401-0000-0000-C000-000000000046} - Locate and then click the following registry key:
HKEY_CLASSES_ROOT\piffile\shellex\IconHandler - Reset the registry key value to:
{00021401-0000-0000-C000-000000000046} - Restart the computer
Disable the WebClient service
Disabling the WebClient service helps protect affected systems from attempts to exploit this vulnerability by blocking the most likely remote attack vector through the Web Distributed Authoring and Versioning (WebDAV) client service. After applying this workaround it is still possible for remote attackers who successfully exploit this vulnerability to cause Microsoft Office Outlook to run programs located on the targeted user's computer or the Local Area Network (LAN), but users will be prompted for confirmation before opening arbitrary programs from the Internet.
To disable the WebClient Service, follow these steps:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Disabled. If the service is running, click Stop.
- Click OK and exit the management application.
Impact of workaround. When the WebClient service is disabled, Web Distributed Authoring and Versioning (WebDAV) requests are not transmitted. In addition, any services that explicitly depend on the Web Client service will not start, and an error message will be logged in the System log. For example, WebDAV shares will be inaccessible from the client computer.
How to undo the workaround.
To re-enable the WebClient Service, follow these steps:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Automatic. If the service is not running, click Start.
- Click OK and exit the management application.
Block the download of LNK and PIF files from the Internet
Blocking the download of LNK and PIF files on the Internet Gateway provides protection against remote exploitation of these attacks. Note that the files can be transferred over WebDAV, so any blocking solution should take this protocol into account.
Block outbound SMB connections on the perimeter firewall
Blocking outbound SMB connections on the perimeter firewall reduces the risk of remote exploitation using file shares.
FAQ for Shortcut Icon Loading Vulnerability - CVE-2010-2568
What is the scope of the vulnerability?
This is a remote code execution vulnerability. 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.
What causes the vulnerability?
When attempting to load the icon of a shortcut, the Windows Shell does not correctly validate specific parameters of the shortcut.
What is the Windows Shell?
The Windows user interface (UI) provides users with access to a wide variety of objects necessary for running applications and managing the operating system. The most numerous and familiar of these objects are the folders and files that reside on computer disk drives. There are also a number of virtual objects that allow the user to perform tasks such as sending files to remote printers or accessing the Recycle Bin. The Shell organizes these objects into a hierarchical namespace and provides users and applications with a consistent and efficient way to access and manage objects.
What is a shortcut?
A shortcut is a link to a file or program, represented by an icon. If you double-click a shortcut, the file or program opens. The shortcut is a mechanism often used to keep frequently used files in a single, easily accessed location, such as a folder or the desktop. Shortcuts are implemented as files with the LNK extension. In addition, shortcuts can also appear as PIF files when they are related to MS-DOS programs.
Will this security update disable the workaround or Microsoft Fix it solution, if I have previously implemented it?
No, the workaround and Microsoft Fix it solution operate independently from the security update. After the security update has been implemented, users who have applied the workaround need to undo it.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the 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.
How could an attacker exploit the vulnerability?
An attacker could present a removable drive to the user with a malicious shortcut file, and an associated malicious binary. When the user opens this drive in Windows Explorer, or any other application that parses the icon of the shortcut, the malicious binary will execute code of the attacker’s choice on the target system.
An attacker could also set up a malicious Web site or a remote network share and place the malicious components on this remote location. When the user browses the Web site using a Web browser such as Internet Explorer or a file manager such as Windows Explorer, Windows attempts to load the icon of the shortcut file, invoking the malicious binary. In addition, an attacker could embed an exploit in a document that supports embedded shortcuts or a hosted browser control (such as but not limited to Microsoft Office documents).
What systems are primarily at risk from the vulnerability?
Desktop systems used to browse untrusted network shares or untrusted Web sites are most at risk from this vulnerability.
What does the update do?
The update addresses this vulnerability by correctly validating the icon reference of a shortcut.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2010-2568.
When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
At the time this security bulletin was released, this vulnerability was being exploited by a number of malware families.

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.
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 | 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. |
/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.

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.
- Click Start, and then click Search.
- In the Search Results pane, click All files and folders under Search Companion.
- In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
- 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. - 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.
