What is Microsoft Windows SharePoint Services 3.0?
Windows SharePoint Services 3.0 provides a platform for collaborative applications, offering a common framework for document management and a common repository for storing documents of all types. It exposes key Windows Server services like Windows Workflow Services and Windows Rights Management Services.
Windows SharePoint Services 3.0 is provided as a free download for supported editions of Windows Server 2003 and Windows Server 2008.
How is Microsoft Windows SharePoint Services 3.0 related to Microsoft Office SharePoint Server 2007?
Microsoft Office SharePoint Server 2007 is an integrated suite of server capabilities built on top of Windows SharePoint Services 3.0.
In what configurations will I need to apply the different updates?
You will need to apply one or both updates, depending on which SharePoint product is installed on your system. For systems with only Microsoft Windows SharePoint Services 3.0 installed, you will need to apply the KB983444 update. For systems with Microsoft Office SharePoint Server 2007 installed, you will need to apply both the KB979445 and KB983444 updates. There is no configuration where you can only have Microsoft Office SharePoint Server 2007 and not Microsoft Windows SharePoint Services 3.0.
I use the 2007 Microsoft Office System Service Pack 1. Are any additional security features included in this update?
Yes, as part of the servicing model for the 2007 Microsoft Office System, when users of Microsoft Office 2007 Service Pack 1 install this update, their systems will be upgraded to security functionality that was initially released with Microsoft Office 2007 Service Pack 2. All updates released after April 24, 2009 for Microsoft Office 2007 will include these security features, which were introduced in the 2007 Microsoft Office System Service Pack 2. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to the environment and configuration of their systems.
The Office component discussed in this article is part of the Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update?
Yes, if the version of the Office Suite installed on your system was delivered with the component discussed in this bulletin, the system will be offered updates for it whether the component is installed or not. The detection logic used to scan for affected systems is designed to check for updates for all components that shipped with the particular Office Suite and offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is included in their version of the Office Suite, will not increase the security risk of that system. On the other hand, users who do choose to install the update will not have a negative impact on the security or performance of a system.
Does the offer to update a non-vulnerable version of Microsoft Office constitute an issue in the Microsoft update mechanism?
No, the update mechanism is functioning correctly in that it detects a lower version of the files on the system than in the update package and thus, offers the update.
I am using an older release of the software discussed in this security bulletin. What should I do?
The affected software listed in this bulletin have been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, visit the Microsoft Support Lifecycle Web site.

Help.aspx XSS Vulnerability - CVE-2010-0817
A cross-site scripting and spoofing vulnerability exists in Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 that could allow an attacker to convince a user to run a malicious script. An attacker who successfully exploited the vulnerability could modify Web browser caches and intermediate proxy server caches. Additionally, an attacker could put spoofed content into those caches. An attacker may also be able to exploit the vulnerability to perform cross-site scripting attacks.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-0817.
Mitigating Factors for Help.aspx XSS Vulnerability - CVE-2010-0817
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:
- Internet Explorer 8 users browsing to a SharePoint site in the Internet Zone are at a reduced risk because, by default, the XSS Filter in Internet Explorer 8 prevents this attack in the Internet Zone. The Internet Explorer 8 XSS Filter, however, is not enabled by default in the Intranet Zone.
- An attacker can cause arbitrary JavaScript to be run by the user clicking the specially crafted URL, but the attacker would not be able to steal the logged-on user's authentication credentials due to the way that SharePoint Server handles the HttpOnly authentication cookie
- The vulnerability cannot be exploited automatically through e-mail. For an attack to be successful, a user must click on a URL that is sent in an e-mail message.
Workarounds for Help.aspx XSS Vulnerability - CVE-2010-0817
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:
Restrict Access to SharePoint Help.aspx
An administrator can apply an access control list to SharePoint Help.aspx to ensure that they can no longer be loaded. This effectively prevents exploitation of the vulnerability using this attack vector.
To restrict access to the vulnerable Help.aspx, run the following commands from a command prompt:
cacls "%ProgramFiles%\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\Help.aspx" /E /P everyone:Ncacls "%ProgramFiles(x86)%\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\Help.aspx" /E /P everyone:NImpact of workaround. This workaround will disable all help functionality from the SharePoint server.
How to undo the workaround.

FAQ for Help.aspx XSS Vulnerability - CVE-2010-0817
What is the scope of the vulnerability?
This is a scripting vulnerability that could result in elevation of privilege in Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 that could allow an attacker to convince a user to run a malicious script. An attacker who successfully exploited this vulnerability could perform cross-site scripting attacks, display spoofed responses to users, or redirect server responses to another user. It may also be possible for an attacker to exploit the vulnerability to modify Web browser caches and intermediate proxy server caches and to put spoofed content in those caches.
What causes the vulnerability?
Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 do not properly validate input that is provided to an HTML query before sending this input to the browser.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited the vulnerability could gain the same user rights on the SharePoint site as the targeted user. The attacker could then run commands against the SharePoint server in the context of the targeted user.
How could an attacker exploit the vulnerability?
In order for an attack to be successful, a user would have to click on an attacker provided, specially crafted link to an affected server.
In an e-mail attack scenario, an attacker could exploit the vulnerability by sending an e-mail message containing the specially crafted link to the user of the targeted affected server and by convincing the user to click on the specially crafted link.
In a Web-based attack scenario, an attacker would have to host a Web site that contains a specially crafted link to the targeted affected server that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes them to the attacker's Web site, and then convince them to click on the specially crafted link.
What systems are primarily at risk from the vulnerability?
Client systems where users browse the Internet are primarily at risk.
What is the Internet Explorer 8 Cross Site-scripting (XSS) Filter?
Cross-site scripting attacks try to exploit vulnerabilities in the Web sites you use. The vulnerability described in this bulletin is an example. In this case, you might receive an e-mail message that contains a specially crafted Web site address that includes a script. When you click on the URL, you are directed to a legitimate SharePoint site where the attacker-provided script is run. Cross-site scripting attacks have emerged as a leading online threat, so Internet Explorer 8 includes a cross-site scripting filter that can detect these types of attacks and disable the harmful scripts. By default, the cross-site scripting filter is turned on in Internet Explorer 8 for the Internet Zone.
What does the update do?
The update addresses the vulnerability by modifying the way that Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 validate input that is provided to an HTTP query before sending this input to the client.
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-2010-0817. The vulnerability was first described in Microsoft Security Advisory 983438.
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, published publicly, that attempts to exploit this vulnerability?
Yes. This security update addresses the vulnerability that potentially could be exploited by using the published proof of concept code. The vulnerability that has been addressed has been assigned Common Vulnerability and Exposure number CVE-2010-0817.
toStaticHTML Information Disclosure Vulnerability - CVE-2010-1257
An information disclosure vulnerability exists in the way that the SharePoint toStaticHTML API sanitizes HTML, that could allow an attacker to 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-2010-1257.
Mitigating Factors for toStaticHTML Information Disclosure Vulnerability - CVE-2010-1257
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:
- Only SharePoint sites that use toStaticHTML are potentially affected.
Workarounds for toStaticHTML Information Disclosure Vulnerability - CVE-2010-1257
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:
- On the Internet Explorer Tools menu, click Internet Options.
- In the Internet Options dialog box, click the Security tab, and then click the Internet icon.
- 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:
- In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
- In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
- 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.
- In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
- Repeat these steps for each site that you want to add to the zone.
- 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.
FAQ for toStaticHTML Information Disclosure Vulnerability - CVE-2010-1257
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 SharePoint site.
What causes the vulnerability?
The vulnerability is caused by the way that the toStaticHTML API sanitizes HTML on a SharePoint site.
What is toStaticHTML?
The toStaticHTML is an API that can be used to sanitize HTML by removing event attributes and script from user input before it is displayed as HTML. For more information, please see the MSDN Library article, toStaticHTML Method.
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 SharePoint site. An attacker could then potentially run script in the security context of the site's users against the target SharePoint site that is using toStaticHTML.
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 SharePoint site. Due to the vulnerability, in specific situations the specially crafted script is not properly sanitized using toStaticHTML, and subsequently this could lead to attacker-supplied script being run in the security context of a user who views the malicious content on the SharePoint site.
For cross-site scripting attacks, this vulnerability requires that a user be visiting a compromised SharePoint site for any malicious action to occur. For instance, after an attacker has successfully submitted specially crafted script to the target SharePoint site, any Web page on that SharePoint 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 on the SharePoint site.
What systems are primarily at risk from the vulnerability?
Systems where users connect to a SharePoint server, 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 toStaticHTML sanitizes HTML content.
Is this vulnerability related to CVE-2010-1257 in MS10-035, Cumulative Security Update for Internet Explorer (982381)?
Yes, the toStaticHTML Information Disclosure Vulnerability, CVE-2010-1257, also affects Internet Explorer.
Are both updates necessary to be installed to be protected from the vulnerability?
No, each update addresses a separate application. Only the update that corresponds with software running on your system needs to be applied.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through responsible 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 and had not seen any examples of proof of concept code published when this security bulletin was originally issued.
Sharepoint Help Page Denial of Service Vulnerability - CVE-2010-1264
A denial of service vulnerability exists in the way that Microsoft SharePoint handles specially crafted requests to the help page. An attacker could exploit the vulnerability by sending specially crafted packets to the targeted SharePoint server which could cause the Web server to become non-responsive until the associated application pool is restarted.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-1264.
Mitigating Factors for Sharepoint Help Page Denial of Service Vulnerability - CVE-2010-1264
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:
- The attacker cannot run arbitrary code on the target SharePoint server. This is a denial of service vulnerability only.
- The attacker must be authenticated on the SharePoint site in order to exploit this vulnerability.
Workarounds for Sharepoint Help Page Denial of Service Vulnerability - CVE-2010-1264
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:

Update Compatibility Evaluator and Application Compatibility Toolkit
Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit.
The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
