General Information

Technical description:

Subsequent to the release of this bulletin, it was determined that the vulnerability addressed also affects other versions of the affected products and components. Microsoft has updated the bulletin with additional information about Windows XP 64-Bit Edition and Office 2000 Server Extensions and also to direct users to an update for these additional affected platforms.

This bulletin addresses two new security vulnerabilities in Microsoft FrontPage Server Extensions, the most serious of which could enable an attacker to run arbitrary code on a user's system.

The first vulnerability exists because of a buffer overrun in the remote debug functionality of FrontPage Server Extensions. This functionality enables users to remotely connect to a server running FrontPage Server Extensions and remotely debug content using, for example, Visual Interdev. An attacker who successfully exploited this vulnerability could be able to run code with IWAM_machinename account privileges on an affected system, or could cause FrontPage Server Extensions to fail.

The second vulnerability is a Denial of Service vulnerability that exists in the SmartHTML interpreter. This functionality is made up of a variety of dynamic link library files, and exists to support certain types of dynamic web content. An attacker who successfully exploited this vulnerability could cause a server running Front Page Server Extensions to temporarily stop responding to requests.

Mitigating factors:

  • Administrators that have installed the Front Page Server extensions included in Windows and then applied Windows 2000 Service Pack 4 are not affected by these vulnerabilities
  • Windows XP does not have FrontPage Server Extensions installed by default
  • Windows NT 4.0 does not have FrontPage Server Extensions installed by default unless you have applied Windows NT4.0 Option Pack

Severity Rating:

Microsoft FrontPage Server Extensions 2000 (For Windows NT4) and Microsoft Office 2000 Server Extensions (Shipped with Office 2000) Critical
Microsoft FrontPage Server Extensions 2000 (Shipped with Windows 2000) Critical
Microsoft FrontPage Server Extensions 2000 (Shipped with Windows XP) Moderate
Microsoft FrontPage Server Extensions 2000 64-bit (Shipped with Windows XP 64-bit) Moderate
Microsoft FrontPage Server Extensions 2002 Critical
Microsoft SharePoint Team Services 2002 (Shipped with Office XP) Critical

The above assessment is based on the types of systems affected by the vulnerability, their typical deployment patterns, and the effect that exploiting the vulnerability would have on them.

Vulnerability identifier for the Buffer Overrun vulnerability: CAN-2003-0822

Vulnerability identifier for SmartHTML interpreter vulnerability: CAN-2003-0824

Microsoft has tested the following workarounds that apply across all the vulnerabilities. These workarounds help block known attack vectors, however they will not correct the underlying vulnerabilities. Workarounds may reduce functionality in some cases; in such cases, the reduction in functionality is identified below.

FrontPage Server Extensions administrators can uninstall FrontPage Server Extensions in Add or Remove programs

  1. From the Start button, choose Control Panel.
  2. Select Add or Remove programs.
  3. Select Add/Remove Windows Components.
  4. Select "Internet Information Services (IIS)" and choose "Details...".
  5. Uncheck "FrontPage 2000 Server Extensions" and choose OK.
  6. Choose Next in the Windows Components Wizard and choose Finish.

Impact of workaround:

With FrontPage Server Extensions uninstalled or disabled webpage and server functionality relying on them will be unavailable or will not operate as expected.

Why have you issued a version 2 of this bulletin?
Subsequent to the release of this bulletin, it was determined that the vulnerability addressed also affects other versions of the affected products and components. Microsoft has updated the bulletin with additional information about Windows XP 64-Bit Edition and Office 2000 Server Extensions and also to direct users to an update for these additional affected platforms.

I have been offered this update from Windows Update and I am running Windows XP, why am I being offered this update?
A change to the detection method that Windows Update uses to offer the update to customers was recently altered to provide it to customers who are not affected by this issue.

Have you re-released this patch?
No - A change in how Windows Update scans and offers this update was introduced on December 9th which prompted users who were not at risk to download it. There has been no change to the update, and customers who were vulnerable were offered the update when it was first released in November.

Are you changing Windows Update to correct the issue?
Yes - Microsoft is currently making a change to the Windows Update detection to correct this problem.

Do I need to install the patch if I have not already?
Microsoft recommends that customers install the update if prompted from Windows Update or Automatic Update. There are no known negative affects with installing this update if offered.

If I installed the update in November, do I need to install the patch again?
No - Customers who were at risk have been offered the update from Windows Update or the Microsoft Download Center since it was first released in November. The update is effective at addressing the issue and customers who have applied the update do not need to reapply it.

How can I determine what version of FrontPage Server Extensions I am running?
To determine the version of FrontPage Server Extensions that is installed on your computer, follow these steps.

Note: 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 fp4awel.dll or fp5awel.dll, and then click Search.
  4. If you have the fp4awel.dll file you your system, you have FrontPage Server Extensions 2000 installed
  5. If you have the fp5awel.dll you have either FPSE 2002 or SharePoint Team Services installed.

To differentiate FrontPage Server Extensions 2002 from SharePoint Team Services do the following:

  1. Open the Control Panel task "Add or Remove Programs".
  2. Check whether "Microsoft SharePoint" is listed as installed software.

If a list entry called "Microsoft SharePoint" exists, then you do have SharePoint Team Services installed.

Note: If you have both fp4awel.dll and fp5awel.dll you need to apply both the FrontPage Server Extension 2000 and FrontPage Server Extension 2002 update.

What are the FrontPage Server Extensions?
FrontPage Server Extensions (FPSE) is a set of tools that can be installed on a web site. They serve two basic functions: to allow authorized personnel to manage the server, add or change content, and perform other tasks; and to add functions that are frequently used by web pages, such as search and forms support.
FPSE installs by default as part of IIS 4.0, 5.0 and 5.1. Only Windows 2000 Server, Windows 2000 Advanced Server, and Windows 2000 Datacenter install IIS by default. IIS can be uninstalled if desired. Microsoft recommends that web administrators uninstall FPSE if not needed.

If I have installed the stand-alone version of FrontPage Server extensions and then applied Windows 2000 Service Pack 4 am I vulnerable?
Yes - You need to install the separate stand-alone update for FrontPage Server Extensions



CAN-2003-0822: BO in FrontPage Server Extensions

What's the scope of the remote debug vulnerability?
This is a buffer overrun vulnerability. An attacker who successfully exploited this vulnerability could cause code of their choice to be executed as though it originated on the local machine. Such code could provide the attacker with the ability to take any desired action on the machine, including adding, deleting or modifying data on the system.

What causes the vulnerability?
The vulnerability results because of an unchecked buffer in one of the FrontPage Server Extensions dll files.

What could the remote debug vulnerability enable an attacker to do?
An attacker who successfully exploited this vulnerability could run code of his or her choice with IWAM_machinename account privileges on an affected system, or could cause FrontPage Server Extensions to fail.

Who could exploit the vulnerability?
Any unauthenticated attacker that can connect to the FrontPage Server Extensions service could seek to exploit this vulnerability

How could an attacker exploit this vulnerability?
An unauthenticated attacker could seek to exploit this vulnerability by sending a specially crafted request to FrontPage Server Extensions which would then cause FrontPage Server Extensions to fail in such a way that an attacker could execute code of his or her choice.

What steps could an administrator take to protect against the vulnerability?
The simplest way to address the vulnerability is to install the update. However, if the update were not installed, a server wouldn't be at risk if FrontPage Server Extensions had been uninstalled.

What does the update do?
The update addresses the vulnerability by removing the remote debugging functionality, as this functionality is no longer supported. Microsoft recommends that customers use the Terminal Server functionality for remote debugging.



CAN-2003-0824: Denial of Service in SmartHTML interpreter

What's the scope of the SmartHTML interpreter vulnerability?
This is a denial of service vulnerability. An attacker who successfully exploited this vulnerability could cause a server running Front Page Server Extensions to temporarily stop responding to requests.

What is the SmartHTML interpreter?
The SmartHTML interpreter is part of FPSE, and supports certain types of dynamic web content. It is made up of a variety of dynamic link library files. Using SmartHTML, a web developer can build a web page that relies on FrontPage features. For example, a web developer might want to embed the current date and time in a web page. In order to do that, the developer might use one of the WebBot components that come with FrontPage.
When the web page author inserts a WebBot into an HTML page, what actually gets inserted is a specially formatted HTML comment. A WebBot comment looks like a standard HTML comment with special notation that identifies the WebBot and its properties. The web page author sets the property values from a dialog box when the WebBot gets inserted. Each WebBot has its own dialog. Microsoft calls the WebBot notation "SmartHTML", and HTML pages containing WebBots "SmartHTML pages".
A WebBot is "executed" when the FrontPage Editor saves the HTML page. A FrontPage Server Extensions application scans the page for embedded WebBot components and replaces them with standard HTML text. As a result of this scanning process, a new page is created containing the standard HTML text generated from the WebBot components and a visitor to the web page sees the date and time rendered on the web page.

What's wrong with the SmartHTML interpreter?
If a request is made to a web server using FrontPage Server Extensions in a particular way, it could have the effect of causing the SmartHTML interpreter to cycle, temporarily consuming all of the server's CPU availability and preventing the server from performing useful work.

What could an attacker do via this vulnerability?
An attacker who successfully exploited this vulnerability could cause a server running Front Page Server Extensions to temporarily stop responding to requests.

Who could exploit the vulnerability?
Any unauthenticated attacker that can connect to the FrontPage Server Extensions service could seek to exploit this vulnerability

How might an attacker exploit the vulnerability?
The attack itself would only require that the attacker send a particular type of request to the SmartHTML interpreter repeatedly.

What steps could an administrator take to protect against the vulnerability?
The simplest way to address the vulnerability is to install the update. However, if the update were not installed, a server wouldn't be at risk if FPSE had been uninstalled, or if the SmartHTML interpreter were not in use. For instance, the IIS Lockdown Tool, if used to configure a static web server, disables the interpreter.

How does the update eliminate the vulnerability?
The update causes the SmartHTML interpreter to properly validate the incoming requests and discard those that are not valid.
