Version: 2.1

General Information

Executive Summary

This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft Internet Information Services (IIS). The more severe vulnerability could allow information disclosure if an attacker sends specially crafted FTP commands to the server.

This security update is rated Moderate for IIS 7.0 on all supported editions of Windows Vista and Windows Server 2008, and IIS 7.5 on all supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by modifying the way IIS manages the permissions of a log file and by modifying the way that IIS handles specially crafted FTP commands. For more information about the vulnerabilities, 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 consider applying the security update using update management software, or by checking for updates using the Microsoft Update service.

An information disclosure vulnerability exists when Microsoft Internet Information Services (IIS) fails to properly protect log files.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-2531.

Mitigating Factors for Password Disclosure Vulnerability - CVE-2012-2531

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:

  • An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
  • The Operational log for IIS is not enabled by default.

Workarounds for Password Disclosure Vulnerability - CVE-2012-2531

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:

  • If you have enabled the "Operational" log for IIS, disable the "Operational" log for IIS-Configuration before assigning a custom account to an Application Pool, and re-enable the "Operational" log after the account has been associated.
  • Use Built-in account identities (e.g. LocalService, ApplicationPoolIdentity, etc.) instead of custom accounts for application pools when possible.
  • Prevent access to EventViewer snap-in to non-Administrators accounts.

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 enter an update file name in the Start Search box.
    2. When the file appears under Programs, right-click the file name and click Properties.
    3. On the General tab, compare the file size with the file information tables provided in the bulletin KB article.

      Note Depending on the edition of the operating system, or the programs that are installed on your system, some files that are listed in the file information table may not be installed.
    4. You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.

      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.
    5. Finally, you can also click the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.
