Color Control Panel Insecure Library Loading Vulnerability - CVE-2010-5082
A remote code execution vulnerability exists in the way that the Color Control Panel handles the loading of DLL files. An attacker who successfully exploited this vulnerability could take complete control of an 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.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-5082.
Mitigating Factors for Color Control Panel Insecure Library Loading Vulnerability - CVE-2010-5082
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 a .icm or .icc file).
- 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 Color Control Panel Insecure Library Loading Vulnerability - CVE-2010-5082
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 Desktop Experience on Windows server 2008 and Windows Server 2008 R2
Systems with the Desktop Experience feature installed are not affected by this vulnerability.
For additional information, including instructions on how to install and remove the Desktop Experience, see TechNet article, Desktop Experience Overview.
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:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Disabled. If the service is running, click Stop.
- 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:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Automatic. If the service is not running, click Start.
- 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 Color Control Panel Insecure Library Loading Vulnerability - CVE-2010-5082
What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
What causes the vulnerability?
The vulnerability is the result of the Color Control Panel improperly restricting the path used when loading external libraries.
What is the Desktop Experience feature in Windows Server 2008?
There are a number of desktop features, such as the Color Control Panel, that are not installed by default on Windows Server 2008. Instead, you can install them all together by installing the Desktop Experience feature on Windows Server 2008. For more information, see the TechNet article, Desktop Experience Overview.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user.
