Microsoft Security Bulletin MS11-086 - Important

Vulnerability in Active Directory Could Allow Elevation of Privilege (2630837)

Published: November 08, 2011

Version: 1.0

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). The vulnerability could allow elevation of privilege if Active Directory is configured to use LDAP over SSL (LDAPS) and an attacker acquires a revoked certificate that is associated with a valid domain account and then uses that revoked certificate to authenticate to the Active Directory domain. By default, Active Directory is not configured to use LDAP over SSL.

This security update is rated Important for Active Directory, ADAM, and AD LDS when installed on supported editions of Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 (except Itanium), Windows 7, and Windows Server 2008 R2 (except Itanium). For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by changing the way that Active Directory verifies certificates against the Certificate Revocation List (CRL). For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.

For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

An elevation of privilege vulnerability exists in Active Directory when configured to use LDAP over SSL (LDAPS). An attacker could exploit this vulnerability by using a previously revoked certificate to authenticate to the Active Directory domain and gain access to network resources or run code under the privileges of a specific authorized user with which the certificate is associated.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-2014.

Mitigating Factors for LDAPS Authentication Bypass Vulnerability - CVE-2011-2014

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:

  • Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.

Workarounds for LDAPS Authentication Bypass Vulnerability - CVE-2011-2014

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:

  • Remove the user account from the domain that was subject to the revoked certificate.
  • Use IP s ec-based connections in "Always check CRL" mode, in addition to using LDAPS.

    For information on how to enable CRL checking with IPsec, see the TechNet article, Certificate revocation list (CRL) verification - an application choice.

    Notes

    1. Use IPsec to encrypt and protect the connection to LDAPS using certificate authentication with CRL checking.
    2. Use IPsec to protect the connection to LDAPS using certificate authentication with CRL checking and no encryption. In this case, LDAPS handles the encryption.

      For affected editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, AuthIP (the IPsec extension that allows user-authentication) can be employed to prevent an attacker from performing IPsec certificate authentication using a machine certificate and then using the revoked user certificate to perform LDAPS authentication.

    3. Use NULL encapsulation for LDAPS to prevent encrypting twice and be aware that certificate authentication on the IPsec level is independent of the authentication happening in SSL. This means that using separate certificates at each layer can still allow access to LDAPS via the expired certificate.

FAQ for LDAPS Authentication Bypass Vulnerability - CVE-2011-2014

What is the scope of the vulnerability? 
This is an elevation of privilege vulnerability. An attacker who successfully exploited this vulnerability could obtain access to network resources or run code under the privileges of a specific authorized user.

What causes the vulnerability? 
The vulnerability is caused when Active Directory is configured to use LDAPS and fails to validate the revocation status of an SSL certificate against the CRL associated with the domain account. This allows a certificate to be accepted as valid even after it has been revoked by the certification authority (CA).

What is a certification authority (CA)?  
Certification authorities are the organizations that issue certificates. They establish and verify the authenticity of public keys that belong to people or other certification authorities, and they verify the identity of a person or organization that asks for a certificate.

What are Active Directory S ervices ? 
Active Directory Services contains an extensible and scalable set of services that enables you to efficiently manage corporate identities, credentials, information protection, and system and application settings. Active Directory Services include Active Directory Certificate Services (AD CS), Active Directory Domain Services (AD DS), Active Directory Federation Services (AD FS), Active Directory Lightweight Directory Services (AD LDS), and Active Directory Rights Management Services (AD RMS).

What is Active Directory Lightweight Directory Service (AD LDS) ?  
Active Directory Lightweight Directory Services (AD LDS) is an independent mode of Active Directory that provides dedicated directory services for applications. AD LDS is available for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. AD LDS replaces Active Directory Application Mode (ADAM), which is available for Windows XP and Windows Server 2003. For more information on AD LDS, see the TechNet article, Active Directory Lightweight Directory Services.

What is Active Directory Application Mode? 
Active Directory Application Mode (ADAM) is a Lightweight Directory Access Protocol (LDAP) directory service that runs as a user service for Windows XP and Windows Server 2003, rather than as a system service. For more information on ADAM, please see the TechNet article, Introducing ADAM.

What is the Lightweight Directory Access Protocol (LDAP)?  
The Lightweight Directory Access Protocol (LDAP) is a directory service protocol that runs directly over the TCP/IP stack. The information model (for both data and namespaces) of LDAP is similar to that of the X.500 OSI directory service, but with fewer features and lower resource requirements than X.500. Unlike most other Internet protocols, LDAP has an associated API that simplifies writing Internet directory service applications. The LDAP API is applicable to directory management and browser applications that do not have directory service support as their primary function. LDAP cannot create directories or specify how a directory service operates.

What is a Certificate Revocation List (CRL)? 
CRL is a digitally signed list, issued by a CA, that contains a list of certificates issued by the CA and subsequently revoked by the CA. For each individual revoked certificate, the listing includes the serial number of the certificate, the date that the certificate was revoked, and the revocation reason. Applications can perform CRL checking to determine a presented certificate's revocation status. For more information on certificate revocation checking, see the TechNet article, Certificate Revocation and Status Checking.

What is LDAP over SSL (LDAPS) ?  
LDAP over SSL (LDAPS) encrypts traffic transmitted between client computers and server computers with a Secure Sockets Layer (SSL)/Transport Layer Security (TLS) technology.

What is Active Directory Domain Services?  
Active Directory Domain Services (AD DS) stores directory data and manages communication between users and domains, including user logon processes, authentication, and directory searches. An Active Directory domain controller is a server that is running AD DS. For more information on AD DS, please see the TechNet article, Active Directory Domain Services.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could obtain access to network resources or run code under the privileges of a specific authorized user. If the user has administrator privileges, 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? 
To exploit this vulnerability, an attacker would first have to acquire a revoked certificate that is associated with a valid account on the domain. An attacker could then exploit this vulnerability by using this previously revoked certificate to authenticate to the Active Directory domain and gain access to network resources or run code under the privileges of a specific authorized user with which the certificate is associated.

What systems are primarily at risk from the vulnerability? 
All systems running an affected operating system with Active Directory services installed are affected by this vulnerability.

What does the update do? 
The update addresses the vulnerability by changing the way that Active Directory verifies the validity of certificates against the CRL.

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.

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, see Microsoft Knowledge Base Article 832475.

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.

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.
