MS03-018: May 2003 cumulative patch for Internet Information Services (IIS) (811114)


The information in this article applies to:

  • Microsoft Internet Information Services version 5.1
  • Microsoft Internet Information Services 5.0
  • Microsoft Internet Information Server 4.0

SYMPTOMS

Microsoft has released a cumulative patch for Internet Information Server (IIS) 4.0, Internet Information Services (IIS) 5.0, and IIS 5.1. This patch includes the functionality of all security patches that have been released for IIS 4.0 since Windows NT 4.0 Service Pack 6a (SP6a), all security patches that have been released for IIS 5.0 since Windows 2000 Service Pack 2 (SP2), and all security patches that have been released for IIS 5.1. Additionally, this patch includes fixes for the following newly discovered security vulnerabilities that affect IIS 4.0, 5.0, and 5.1:
  • A cross-site scripting (CSS) vulnerability that affects IIS 4.0, 5.0, and 5.1. This vulnerability involves the error message that is returned to advise that a requested URL has been redirected. An attacker who lures a user to click a link on the attacker's Web site could relay a request that contains a script to a third-party Web site running IIS. This request could cause the third-party site's response (still including the script) to be sent to the user. The script could then run by using the security settings of the third-party site instead of the security settings of the attacker's site.
  • A buffer overrun that results because IIS 5.0 does not correctly validate requests for specific types of Web pages that are known as server-side includes. An attacker would have to be able to upload a server-side include page to a vulnerable IIS server. If the attacker then requests this page, a buffer overrun might occur. This buffer overrun would permit the attacker to run the code of his or her choice on the server with user-level permissions.
  • A denial of service vulnerability that results because of a flaw in the way that IIS 4.0 and 5.0 allocate memory requests when they construct headers to be returned to a Web client. An attacker would have to be able to upload an ASP page to a vulnerable IIS server. When the attacker calls to this ASP page, the page tries to return a very large header to the calling Web client. Because IIS does not limit the memory that can be used in this case, this might cause IIS to run out of memory and fail.
  • A denial of service vulnerability that results because IIS 5.0 and 5.1 do not correctly handle an error condition when a WebDAV request that is too long is passed to them. An attacker could use this problem to cause IIS to fail. However, by default, both IIS 5.0 and 5.1 restart immediately after this failure.
Mitigating factors for Redirection Cross-Site Scripting:
  • IIS 6.0 is not affected.
  • The vulnerability can only be exploited if the attacker can lure another user to visit a Web page and then click a link on the Web page, or lure the user to open an HTML mail.
  • The destination page must be an ASP page that uses Response.Redirect to redirect the client to a new URL that is based on the incoming URL of the current request.
Mitigating factors for Server Side Include Web Pages Buffer Overrun:
  • IIS 4.0, IIS 5.1, and IIS 6.0 are not affected.
  • By default, the IIS Lockdown tool disables the Ssinc.dll mapping (http://www.microsoft.com/technet/security/tools/locktool.mspx). This setting blocks this type of attack.
  • By default, IIS 5.0 runs under a user account and not under the system account. Therefore, an attacker who successfully exploited this vulnerability would gain only user level permissions instead of administrative level permissions.
  • An attacker must be able to upload files to the IIS Server.
Mitigating factors for Headers Denial of Service:
  • IIS 5.1 is not affected.
  • An attacker must be able to upload files to the IIS server.
  • IIS 5.0 automatically restarts after this failure.
Mitigating factors for WebDAV Denial of Service:

RESOLUTION

Hotfix information

Caution If you have an application that is running under IIS and the application extends the IIS metabase schema, installing the security rollup fix may remove these extensions and your application may not function correctly. To determine if a third-party application extends the metabase schema, contact the third-party vendor.

Some ProClarity products are known to be affected by this security rollup fix, including the following products:
  • ProClarity Enterprise Server 4.0 and later
  • ProClarity Analytics Server 5.0, 5.1, and 5.2
To resolve the issue BEFORE you install the security rollup, use one of the following options:
  • Create a backup of the metabase, install the security rollup fix, and then restore the metabase afterward. (Note that Microsoft does not recommend this because of possible compatibility issues.)

    For more information about how to create a metabase backup, click the following article number to view the article in the Microsoft Knowledge Base:

    302573 How to back up and restore IIS

  • Install Microsoft Windows 2000 Service Pack 4 (SP4). Windows 2000 SP4 includes the security rollup.
  • Contact Microsoft Product Support Services to receive a hotfix that corrects this problem.
If you have already installed the security rollup fix, and you have a problem with your application that extends the IIS metabase schema, the application must re-extend the metabase schema. This may require reinstalling the product.

STATUS

Microsoft has confirmed that this problem may cause a degree of security vulnerability in the Microsoft products that are listed in the "Applies To" section. This problem was first corrected in Windows XP Service Pack 2.

MORE INFORMATION

For more information about this vulnerability, visit the following Microsoft Web site:

http://www.microsoft.com/technet/security/bulletin/MS03-018.mspx

Customers who use Site Server must be aware that a previously documented issue that involves intermittent authentication errors affects this patch and a small number of other patches. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

317815 Site Server logon problems occur after you apply certain Windows 2000 hotfixes

These patches do not include fixes for vulnerabilities that involve non-IIS products, such as the Microsoft FrontPage Server Extensions and Microsoft Index Server, although these products are closely associated with IIS and are typically installed on IIS servers. However, there is one exception. The fix for the vulnerability that affects Index Server is included in this patch because of the seriousness of the issue for IIS servers. (This vulnerability is discussed in Microsoft Security Bulletin MS01-033.) At the time that this article was written, the Microsoft Security Bulletins that discuss these vulnerabilities are as follows:

Microsoft Security Bulletin MS02-053

Microsoft Security Bulletin MS02-050

Microsoft Security Bulletin MS01-043

Microsoft Security Bulletin MS01-025

Microsoft Security Bulletin MS00-084

Microsoft Security Bulletin MS00-018

Microsoft Security Bulletin MS00-006

The fixes for the following vulnerabilities that affect IIS 4.0 are not included in the patch because they require administrative action instead of a software change. Administrators must make sure that they not only apply this patch, but also take the administrative action that is described in the following bulletins:

Microsoft Security Bulletin MS00-028

Microsoft Security Bulletin MS00-025

Microsoft Security Bulletin MS99-025 (this bulletin discusses the same issue as Microsoft Security Bulletin MS98-004)

Microsoft Security Bulletin MS99-013
