FAQ for IIS Repeated Parameter Request Denial of Service Vulnerability - CVE-2010-1899

What is the scope of the vulnerability? 
This is a denial of service vulnerability. If an attacker sends a specially crafted request to a Web server, the server could become unresponsive. The vulnerability does not cause the server to fail or cause any data to be lost, and the server would eventually resume normal operation with a service reset.

What causes the vulnerability? 
This denial of service vulnerability is caused by a stack overflow in the ASP script processing code.

What might an attacker use the vulnerability to do? 
This is a denial of service vulnerability. An attacker who exploited this vulnerability could cause the affected system to stop responding and automatically restart. During that time, the server would be unable to respond to requests. If the attacker causes the service to restart five times, the service will then fail to restart without administrator interaction. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate their user rights, but it could cause the affected service to stop accepting requests.

How could an attacker exploit the vulnerability? 
An attacker could send specially crafted URL requests to a Web site hosting .asp pages to exploit this denial of service vulnerability.

What systems are primarily at risk from the vulnerability? 
All systems running Microsoft Internet Information Services could be affected by this vulnerability.

What does the update do? 
This update modifies the way that IIS and asp.dll handle specially crafted HTTP requests.

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.

A remote code execution vulnerability exists in Internet Information Services (IIS) that an attacker could exploit by sending specially crafted HTTP requests to IIS servers with FastCGI enabled.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-2730.

Mitigating Factors for Request Header Buffer Overflow Vulnerability - CVE-2010-2730

  • FastCGI is not enabled by default in IIS.

Workarounds for Request Header Buffer Overflow Vulnerability - CVE-2010-2730

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 FastCGI
    1. Launch the Server Manager and edit the Roles.
    2. Deselect the CGI check box and click Next.

    Impact of workaround. Modules that depend on FastCGI will no longer work.

    How to undo the workaround.

    Launch the Server Manager and add the CGI feature under Web Server.

  • Install the URL Rewrite module

    You are protected when this module is installed, whether or not you are using it. For information on URL Rewrite, see URL Rewrite.

FAQ for Request Header Buffer Overflow Vulnerability - CVE-2010-2730

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. A remote attacker who successfully exploited this vulnerability could then perform actions on the IIS server with the same rights as the Worker Process Identity (WPI). This identity is configured to be a virtual application pool identity on Windows 7 and Windows Server 2008 R2.

What causes the vulnerability? 
This vulnerability is caused by the way that IIS servers with FastCGI enabled handle request headers.

What is FastCGI? 
FastCGI for IIS enables popular application frameworks that support the FastCGI protocol to be hosted on the IIS Web server in a high-performance and reliable way. FastCGI provides a high-performance alternative to the Common Gateway Interface (CGI), a standard way of interfacing external applications with Web servers that has been supported as part of the IIS feature-set since the very first release.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability 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.

How could an attacker exploit the vulnerability? 
A remote code execution vulnerability exists in the way that IIS handles request headers to IIS servers with FastCGI enabled. An attacker could exploit this vulnerability by creating a specially crafted HTTP request.

What systems are primarily at risk from the vulnerability? 
Web servers with FastCGI enabled that host content.

What does the update do? 
This update modifies the way that IIS servers with FastCGI enabled handle request headers.

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.

Mitigating Factors for Directory Authentication Bypass Vulnerability - CVE-2010-2731

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:

  • Sites that are not using authentication are not vulnerable to this. There is no elevation of privilege attack vector for sites with only anonymous authentication.

Workarounds for Directory Authentication Bypass Vulnerability - CVE-2010-2731

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:

  • Install and Use URLScan

    URLScan will help protect against a large number of issues stemming from improperly formed URL requests including the publicly described issues addressed by this bulletin. URLScan does not protect your system as comprehensively as either the mitigation code module or the global.asax script below. For information on URLScan, see the TechNet article, UrlScan Security Tool.

FAQ for Directory Authentication Bypass Vulnerability - CVE-2010-2731

What is the scope of the vulnerability?

Deployment Information

Installing the Update

When you install this security update, the installer checks whether 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.

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.

    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 a file name from the appropriate file information table, and then click Search.
    4. 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.
    5. 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.
