Workarounds for Windows Vista Firewall Blocking Rule Information Disclosure Vulnerability – CVE-2007-3038

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 Teredo

You can help protect against this vulnerability by disabling the Teredo transport mechanisum. This prevents Teredo from being used as a transport or mechanism to traverse the NAT. To do this, follow these steps:

1.


Right-click on the Runmenu item and choose Run as elevated.

2.


In the Run box, type Netshintter set st disable


Disable Teredo by modifying the registry.

Teredo can also be disabled by modifying the Windows registry. Create the following registry value to disable Teredo as a transport mechanism.

Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe

1.


Start, click Run, type “regedit" (without the quotation marks), and then click OK.


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\P
arameters\


DisabledComponents.


0x8 to disable Teredo.

Impact of Workaround: If you disable Teredo, depending on network configuration, applications that use the Teredo interface will not function or be accessible.


Block inbound and outbound Teredo UDP traffic using a Windows Vista Firewall setting.
A custom firewall rule can be created that blocks all Teredo related traffic from communicating with the affected system. To do this, follow these steps:

1.


Click Control Panel, click Classic View.

2.


Click Administrative Tools and then Double-click Windows Firewall with Advanced Security.

3.


Select Inbound Rules.

4.


Select CoreNetworking - Teredo (UDP-In).

5.


Right click, select Properties.

6.


Select “Block the connections”.

7.


Select Outbound Rules.

8.


Select Core Networking - Teredo (UDP-Out).

9.


Right click, select Properties.

10.


Select “Block the connections”.

Impact of Workaround: If you block Teredo network traffic using the custom Windows Firewall rule, applications that use the Teredo interface will not function properly or be accessible.


Block Teredo UDP outbound traffic on perimeter firewalls.

Blocking all outbound UDP traffic destined to port 3544 at the network perimeter will disallow affected Vista systems from communicating with external attempts to exploit the vulnerability.

Impact of Workaround:Depending on network configuration, applications that use the Teredo interface will not function or be accessible outside of the network perimeter.

FAQ for Windows Vista Firewall Blocking Rule Information Disclosure Vulnerability – CVE-2007-3038

What is the scope of the vulnerability?
This is an information disclosure vulnerability. An attacker who successfully exploited this vulnerability could gain information about the vulnerable system and be able to identify it’s existence on the network.

What causes the vulnerability
On Windows Vista, network traffic is handled incorrectly through the Teredo interface which causes some firewall rules to by bypassed.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could bypass some of the firewall rules of an affected system.

How could an attacker exploit the vulnerability?
An attacker could remotely activate the Teredo interface under certain configuration scenarios or would have to convince a user to click a link containing a Teredo network address on a Web site, in an e-mail message or Instant Messenger message. Clicking the link would cause Teredo to enter an active state and subsequently cause the affected host to initiate communications with the attacker. This would then allow the attacker to know the target’s Teredo network address which could then be used to send communications to the host that are not blocked by the local Windows Vista firewall. Additionally, as Teredo facilitates network tunneling once a connection is established with an attacker, it would also be possible for the communications to potentially bypass network perimeter firewalls.

What is Teredo?
Teredo is an IPv6 transition technology that provides address assignment and host-to-host automatic tunneling for unicast IPv6 traffic when IPv6/IPv4 hosts are located behind one or multiple IPv4 network address translators (NATs). To traverse IPv4 NATs, IPv6 packets are sent as IPv4-based User Datagram Protocol (UDP) messages. See the TechNet Web site for more information regarding the Teredo service.

Could the vulnerability be exploited over the Internet?
Yes, this vulnerability could be exploited over the internet once a user has clicked on specially crafted link containing an IPv6 address causing the Teredo interface to be activated.

What systems are primarily at risk from the vulnerability?
Any Windows Vista system where the network profile is not set to “Public” could be at risk from this vulnerability. Windows Vista systems that use Remote Assistance or Meeting Space may be at more risk because these applications automatically place Teredo in an active state.

What does the update do?
The update modifies the Windows Vista firewall and core network components to ensure that the default behavior is to block unsolicited traffic over the Teredo interface.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through responsible 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 and had not seen any examples of proof of concept code published 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 Windows hotfix. If you have previously installed a hotfix to update one of these files, the installer will apply the LDR version of this update. Otherwise, the installer will apply the GDR version of the update. The LDR version of a file has a higher version number than the GDR version of a file. For more information about this behavior, see Microsoft Knowledge Base Article 824994.For more information about the installer, see Microsoft Knowledge Base Article 934307.

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
Switch Description

/?, /h, /help


Displays help on supported switches.

/quiet


Suppresses the display of status or error messages.

/norestart


When combined with /quiet, the system will not be restarted after installation even if a restart is required to complete installation.

Note You can combine these switches into one command. For backward compatibility, the security update also supports 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. For more information about the Update.exe 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.

Removing the Update

To remove this update, use the Add or Remove Programs tool in Control Panel.

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 versions of Microsoft Windows, the following steps may be different on your computer. 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 version of the operating system or programs installed, 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 computer 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.
