Microsoft has not identified any workarounds for this vulnerability.

FAQ for HTML Sanitization Vulnerability - CVE-2010-3243

What is the scope of the vulnerability? 
This is an information disclosure vulnerability. An attacker who successfully exploited the vulnerability could perform persistent cross-site scripting attacks against users of a site that is filtering HTML content via SafeHTML.

What causes the vulnerability? 
The vulnerability is caused by the way that the SafeHTML function sanitizes HTML.

What is cross-site scripting? 
Cross-site scripting (XSS) is a class of security vulnerability that can enable an attacker to inject script code into a user's session with a Web site. The vulnerability can affect Web servers that dynamically generate HTML pages. If these servers embed browser input in the dynamic pages that they send back to the browser, these servers can be manipulated to include maliciously supplied content in the dynamic pages. This can allow malicious script to be executed. Web browsers may perpetuate this problem through their assumptions of "trusted" sites and their use of cookies to maintain persistent state with the Web sites that they frequent. An XSS attack does not modify Web site content. Instead, it inserts new, malicious script that can execute at the browser in the context that is associated with a trusted server.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited the vulnerability could perform cross-site scripting attacks against users of a targeted site that uses SafeHTML to sanitize HTML. An attacker could then potentially run scripts on behalf of the targeted site's users.

How could an attacker exploit the vulnerability? 
To exploit this vulnerability, an attacker must have the ability to submit a specially crafted script to a target site using SafeHTML. Due to the vulnerability, in specific situations the specially crafted script is not properly sanitized, which subsequently could lead to an attacker-supplied script being run in the security context of a user who views the malicious content.

For cross-site scripting attacks, this vulnerability requires that a user be visiting a compromised site for any malicious action to occur. For instance, after an attacker has successfully submitted specially crafted script to the targeted site using SafeHTML, any Web page on that site that contains the specially crafted script is a potential vector for persistent cross-site scripting attacks. When a user visits a Web page that contains the specially crafted script, the script could be run in the security context of the user.

What systems are primarily at risk from the vulnerability? 
Systems where users connect to a server that uses SafeHTML to sanitize HTML content, such as workstations or terminal servers, are primarily at risk.

What does the update do? 
The update addresses the vulnerability by modifying the way that SafeHTML sanitizes HTML content.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

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 when this security bulletin was originally issued.

An information disclosure vulnerability exists in the way that the SafeHTML function sanitizes HTML. An attacker who successfully exploited this vulnerability could perform cross-site scripting attacks and run script in the security context of the logged-on user.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-3324.

Mitigating Factors for HTML Sanitization Vulnerability - CVE-2010-3324

Microsoft has not identified any mitigating factors for this vulnerability.

Workarounds for HTML Sanitization Vulnerability - CVE-2010-3324

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:

  • Read e-mails in plain text

    To help protect yourself from the e-mail attack vector, read e-mail messages in plain text format.

    Microsoft Office Outlook 2002 users who have applied Office XP Service Pack 1 or a later version and Microsoft Office Outlook Express 6 users who have applied Internet Explorer 6 Service Pack 1 or a later version can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.

    Digitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.

    For information about this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.

    Impact of workaround. E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:

    • The changes are applied to the preview pane and to open messages.
    • Pictures become attachments so that they are not lost.
    • Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.
  • Set Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones

    You can help protect against exploitation of this vulnerability by changing your settings for the Internet security zone to block ActiveX controls and Active Scripting. You can do this by setting your browser security to High.

    To raise the browsing security level in Internet Explorer, follow these steps:

    1. On the Internet Explorer Tools menu, click Internet Options.
    2. In the Internet Options dialog box, click the Security tab, and then click the Internet icon.
    3. Under Security level for this zone, move the slider to High. This sets the security level for all Web sites you visit to High.

    Note If no slider is visible, click Default Level, and then move the slider to High.

    Note Setting the level to High may cause some Web sites to work incorrectly. If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the security setting set to High.

    Impact of workaround. There are side effects to blocking ActiveX Controls and Active Scripting. Many Web sites that are on the Internet or on an intranet use ActiveX or Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX Controls to provide menus, ordering forms, or even account statements. Blocking ActiveX Controls or Active Scripting is a global setting that affects all Internet and intranet sites. If you do not want to block ActiveX Controls or Active Scripting for such sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone".

    Add sites that you trust to the Internet Explorer Trusted sites zone

    After you set Internet Explorer to block ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted Web sites exactly as you do today, while helping to protect yourself from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.

    To do this, follow these steps:

    1. In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
    2. In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
    3. If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
    4. In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
    5. Repeat these steps for each site that you want to add to the zone.
    6. Click OK two times to accept the changes and return to Internet Explorer.

    Note Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and it requires an ActiveX Control to install the update.

  • Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone

    You can help protect against exploitation of this vulnerability by changing your settings to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone. To do this, follow these steps:

    1. In Internet Explorer, click Internet Options on the Tools menu.
    2. Click the Security tab.
    3. Click Internet, and then click Custom Level.
    4. Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
    5. Click Local intranet, and then click Custom Level.
    6. Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
    7. Click OK two times to return to Internet Explorer.

    Note Disabling Active Scripting in the Internet and Local intranet security zones may cause some Web sites to work incorrectly. If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly.

    Impact of workaround. There are side effects to prompting before running Active Scripting. Many Web sites that are on the Internet or on an intranet use Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use Active Scripting to provide menus, ordering forms, or even account statements. Prompting before running Active Scripting is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click Yes to run Active Scripting. If you do not want to be prompted for all these sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone".

    Add sites that you trust to the Internet Explorer Trusted sites zone

    After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted Web sites exactly as you do today, while helping to protect you from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.

    To do this, follow these steps:

    1. In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
    2. In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
    3. If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
    4. In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
    5. Repeat these steps for each site that you want to add to the zone.
    6. Click OK two times to accept the changes and return to Internet Explorer.

    Note Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and it requires an ActiveX Control to install the update.

Installing the Update

You can install the update from the appropriate download link in the Affected and Non-Affected Software section. If you installed your application from a server location, the server administrator must instead update the server location with the administrative update and deploy that update to your system. For more information about Administrative Installation Points, refer to the Office Administrative Installation Point information in the Detection and deployment Tools and Guidance subsection.

This security update requires that Windows Installer 3.1 or later be installed on the system.

To install the 3.1 or later version of Windows Installer, visit one of the following Microsoft Web sites:

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.

Supported Security Update Installation Switches
SwitchDescription
/? or /helpDisplays usage dialog.
/passive Specifies passive mode. Requires no user interaction; users see basic progress dialogs but cannot cancel.
/quiet Specifies quiet mode, or suppresses prompts, when files are being extracted.
/norestart Suppresses restarting the system if the update requires a restart.
/forcerestart Automatically restarts the system after applying the update, regardless of whether the update requires the restart.
/extract Extracts the files without installing them. You are prompted for a target folder.
/extract:<path> Overrides the install command that is defined by author. Specifies the path and name of the Setup.inf or .exe file.
/lang:<LCID> Forces the use of a specific language, when the update package supports that language.
/log:<log file> Enables logging, by both Vnox and Installer, during the update installation.

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.
