To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-1849.

Mitigating Factors for Lync Insecure Library Loading Vulnerability - CVE-2012-1849

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:

  • For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a legitimate file (such as an .ocsmeet file) from this location that is then loaded by a vulnerable application.
  • The file sharing protocol, Server Message Block (SMB), is often disabled on the perimeter firewall. This limits the potential attack vectors for this vulnerability.
  • An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Workarounds for Lync Insecure Library Loading Vulnerability - CVE-2012-1849

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 loading of libraries from WebDAV and remote network shares

    Note See Microsoft Knowledge Base Article 2264107 to deploy a workaround tool that allows customers to disable the loading of libraries from remote network or WebDAV shares. This tool can be configured to disallow insecure loading on a per-application or a global system basis.

    Customers who are informed by their vendor of an application being vulnerable can use this tool to help protect against attempts to exploit this issue.

    Note See Microsoft Knowledge Base Article 2264107 to use the automated Microsoft Fix it solution to deploy the registry key to block the loading of libraries for SMB and WebDAV shares. Note that this Fix it solution does require you to install the workaround tool also described in Microsoft Knowledge Base Article 2264107 first. This Fix it solution only deploys the registry key and requires the workaround tool in order to be effective. We recommend that administrators review the KB article closely prior to deploying this Fix it solution.

  • Disable the WebClient service

    Disabling the WebClient service helps protect affected systems from attempts to exploit this vulnerability by blocking the most likely remote attack vector through the Web Distributed Authoring and Versioning (WebDAV) client service. After applying this workaround it is still possible for remote attackers who successfully exploit this vulnerability to cause the system to run programs located on the targeted user's computer or the Local Area Network (LAN), but users will be prompted for confirmation before opening arbitrary programs from the Internet.

    To disable the WebClient Service, follow these steps:

    1. Click Start, click Run, type Services.msc and then click OK.
    2. Right-click WebClient service and select Properties.
    3. Change the Startup type to Disabled. If the service is running, click Stop.
    4. Click OK and exit the management application.

    Impact of workaround. When the WebClient service is disabled, Web Distributed Authoring and Versioning (WebDAV) requests are not transmitted. In addition, any services that explicitly depend on the Web Client service will not start, and an error message will be logged in the System log. For example, WebDAV shares will be inaccessible from the client computer.

    How to undo the workaround.

    To re-enable the WebClient Service, follow these steps:

    1. Click Start, click Run, type Services.msc and then click OK.
    2. Right-click WebClient service and select Properties.
    3. Change the Startup type to Automatic. If the service is not running, click Start.
    4. Click OK and exit the management application.
  • Block TCP ports 139 and 445 at the firewall

    These ports are used to initiate a connection with the affected component. Blocking TCP ports 139 and 445 at the firewall will help protect systems that are behind that firewall from attempts to exploit this vulnerability. Microsoft recommends that you block all unsolicited inbound communication from the Internet to help prevent attacks that may use other ports. For more information about ports, see the TechNet article, TCP and UDP Port Assignments.

    Impact of workaround. Several Windows services use the affected ports. Blocking connectivity to the ports may cause various applications or services to not function. Some of the applications or services that could be impacted are listed below:

    • Applications that use SMB (CIFS)
    • Applications that use mailslots or named pipes (RPC over SMB)
    • Server (File and Print Sharing)
    • Group Policy
    • Net Logon
    • Distributed File System (DFS)
    • Terminal Server Licensing
    • Print Spooler
    • Computer Browser
    • Remote Procedure Call Locator
    • Fax Service
    • Indexing Service
    • Performance Logs and Alerts
    • Systems Management Server
    • License Logging Service

    How to undo the workaround. Unblock TCP ports 139 and 445 at the firewall. For more information about ports, see TCP and UDP Port Assignments.

FAQ for Lync Insecure Library Loading Vulnerability - CVE-2012-1849

What is the scope of the vulnerability? 
This is a remote code execution vulnerability.

What causes the vulnerability? 
The vulnerability is caused when Microsoft Lync incorrectly restricts the path used for loading external libraries.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could run arbitrary code as the current user. If the current user is logged-on with administrative user rights, an attacker 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

How could an attacker exploit the vulnerability? 
An attacker could convince a user to open a legitimate Microsoft Lync related file (such as an .ocsmeet file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the legitimate file, Microsoft Lync could attempt to load the DLL file and execute any code it contained.

In an email attack scenario, an attacker could exploit the vulnerability by sending a legitimate Microsoft Lync-related file (such as an .ocsmeet file) to a user, and convincing the user to place the attachment into a directory that contains a specially crafted DLL file and to open the legitimate file. Then, while opening the legitimate file, Microsoft Lync could attempt to load the DLL file and execute any code it contained.

In a network attack scenario, an attacker could place a legitimate Microsoft Lync-related file and a specially crafted DLL in a network share, a UNC, or WebDAV location and then convince the user to open the file.

What systems are primarily at risk from the vulnerability? 
Systems where Microsoft Lync is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do? 
The update addresses this vulnerability by correcting how Microsoft Lync loads external libraries.

Is this vulnerability related to Microsoft Security Advisory 2269637?
Yes, this vulnerability is related to the class of vulnerabilities, described in Microsoft Security Advisory 2269637, that affects how applications load external libraries.

When this security bulletin was issued, had this vulnerability been publicly disclosed?

Deployment Information

Installing the Update

You can install the update from the appropriate download link in the Affected and Non-Affected Software section. If you installed your application from a server location, the server administrator must instead update the server location with the administrative update and deploy that update to your system. For more information about Administrative Installation Points, refer to the Office Administrative Installation Point information in the Detection and deployment Tools and Guidance subsection.

This security update requires that Windows Installer 3.1 or later version be installed on the system.

To install the 3.1 or later version of Windows Installer, visit one of the following Microsoft websites:

For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.

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.
