A spoofing vulnerability exists in the Microsoft Windows SChannel authentication component when using certificate based authentication. An attacker who successfully exploited this vulnerability would be able to authenticate to a server using only an authorized user’s digital certificate and without the associated private key.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2009-0085.

Mitigating Factors for SChannel Spoofing Vulnerability - CVE-2009-0085

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:

  • Customers are only affected when the certificate used for authentication has already been disclosed to the attacker through other means. In the case of an IIS web server, certificates are not transferred in clear text during the authentication process.
  • Only locally configured user accounts are vulnerable. Customers who map certificate-authenticated users of their application against an Active Directory domain are not affected by this vulnerability.

Workarounds for SChannel Spoofing Vulnerability - CVE-2009-0085

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:

  • Customers can implement Active Directory certificate mapping, which is not affected by this vulnerability. Active Directory certificate mapping enables a user with a trusted public key to access domain resources without typing a user name and a password. A client certificate can be directly mapped to an Active Directory user account.

    For more information on the different ways of configuring certificate mapping, see Map certificates to user accounts.

FAQ for SChannel Spoofing Vulnerability - CVE-2009-0085

What is the scope of the vulnerability? 
A spoofing vulnerability exists in the Microsoft Windows SChannel authentication component when using certificate based authentication. An attacker who successfully exploited this vulnerability could impersonate another user and authenticate against a protected server using the public component of the user’s authentication credential.

What causes the vulnerability? 
The SChannel authentication component does not apply sufficient validation of certain Transport Layer Security (TLS) handshake messages to ensure that the client does in fact have access to the private key linked to the certificate used for authentication.

What is the Secure Channel (SChannel) security package? 
The Secure Channel (SChannel) security package is a Security Support Provider (SSP) that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) Internet standard authentication protocols. These components are used to implement secure communications in support of several common internet and network applications, such as web browsing. SChannel is part of the security package that helps provide an authentication service to provide secure communications between client and server. For more information about SChannel, visit the SChannel web site on MSDN.

What is an x.509 digital certificate? 
Encryption techniques using public and private keys require a public-key infrastructure (PKI) to support the distribution and certification of public keys. Digital certificates package public keys, information about the algorithms used, owner or subject data, the digital signature of a Certificate Authority that has verified the subject data, and a date range during which the certificate can be considered valid.

Digital certificates can be validated by a client such as Internet Explorer to ensure that the server to which a user is connecting is in fact the legitimate server for that host name. However, certificates can also be used as a security credential for user authentication and authorization.

What is the Microsoft Secure Sockets Library? 
The Microsoft Secure Sockets Layer library contains support for a number of secure communication protocols. These include Transport Layer Security 1.0 (TLS 1.0), Secure Sockets Layer 3.0 (SSL 3.0), the older and seldom-used Secure Sockets Layer 2.0 (SSL 2.0), and Private Communication Technology 1.0 (PCT 1.0) protocol.

These protocols provide an encrypted connection between a server and a client system. SSL can help protect information when users connect across public networks such as the Internet. SSL support requires an SSL certificate, which must be installed on a server. For more information about SSL, see XADM: How Secure Sockets Layer Works.

What is a TLS handshake? 
The Transport Layer Security (TLS) Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When establishing a secure session, the Handshake Protocol manages the following:

  • Cipher suite negotiation
  • Authentication of the server and optionally, the client
  • Session key information exchange

What is a Security Support Provider (SSP)? 
A Security Support Provider implements a common interface between transport-level applications, such as Microsoft Remote Procedure Call (RPC), and security providers, such as Windows Distributed Security. It does this by making one or more security packages available to applications. Each security package provides mappings between an application's security support provider interface function calls and an actual security protocol’s functions. Security packages support security protocols such as Kerberos authentication and the Microsoft LAN Manager.

What might an attacker use the vulnerability to do? 
An attacker could use this vulnerability to authenticate against a protected server and impersonate an authorized user, despite not having access to the authorized user’s private key, which is normally required for successful authentication when the server is configured to require client authentication.

How could an attacker exploit the vulnerability? 
An attacker would need to gain access to the public component of the actual certificate used by the end user for authentication. He could then craft a Transport Layer Security (TLS) packet to bypass the validation the SChannel component applies to ensure that the private key is in fact present during authentication.

In the most common deployments, certificates used for client authentication have only a single intended purpose configured in a Windows client. These certificates are only transferred for one specific purpose, such as web authentication. In the case of an SSL connection to an Internet Information Services (IIS) web server, the public key is never transferred in cleartext. However, in instances where a single certificate is used for client authentication and other purposes simultaneously, such as in the case of the signing of e-mail, or the certificate is used to authenticate against multiple web sites, the public key may be more widely distributed.

What systems are primarily at risk from the vulnerability? 
This vulnerability affects services such as web servers that use certificate based authentication and require the user to prove their possession of the certificate's corresponding private key during the authentication process.

What does the update do? 
The update removes the vulnerability by modifying the way that the server parses key exchange data during the TLS handshake.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued. This security bulletin addresses the privately disclosed vulnerability as well as additional issues discovered through internal investigations.

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.

    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.

Deployment Information

Installing the Update

When you install this security update, the installer checks to see if 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.

Supported Security Update Installation Switches
SwitchDescription
/help Displays the command-line options.
Setup Modes
/passive Unattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the computer will restart in 30 seconds.
/quiet Quiet mode. This is the same as unattended mode, but no status or error messages are displayed.
Restart Options
/norestart Does not restart when installation has completed.
/forcerestart Restarts the computer after installation and force other applications to close at shutdown without saving open files first.
/warnrestart[:x] Presents a dialog box with a timer warning the user that the computer will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch.
/promptrestart Displays a dialog box prompting the local user to allow a restart.
Special Options
/overwriteoem Overwrites OEM files without prompting.
/nobackup Does not back up files needed for uninstall.
/forceappsclose Forces other programs to close when the computer shuts down.
/log:path Allows the redirection of installation log files.
/integrate:path Integrates the update into the Windows source files. These files are located at the path that is specified in the switch.
/extract[:path] Extracts files without starting the Setup program.
/ER Enables extended error reporting.
/verbose Enables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly.

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.
