| Vector | AV:A/AC:M/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
Microsoft Windows Server 2003 SP2
Microsoft Windows Server 2008 SP2 and R2 SP1
Microsoft Windows Server 2012 Gold and R2
Description
A spoofing issue exists in the NETLOGON service, allowing remote attackers to spoof the computer name of a secure channel's endpoint and obtain sensitive session information by running a crafted application and leveraging the ability to sniff network traffic. This issue arises when the Netlogon service improperly establishes a secure communications channel belonging to a different machine with a spoofed computer name. To exploit this, an attacker must first be logged on to a domain-joined system and be able to observe network traffic, then run a specially crafted application to establish a secure channel connection belonging to a different computer, potentially using the established secure channel to obtain session-related information for the actual secure channel of the spoofed computer.
Recommendations
For Microsoft Windows Server 2003 SP2, update to a version that includes the fix for the NETLOGON Spoofing Vulnerability.
For Microsoft Windows Server 2008 SP2 and R2 SP1, update to a version that includes the fix for the NETLOGON Spoofing Vulnerability.
For Microsoft Windows Server 2012 Gold and R2, update to a version that includes the fix for the NETLOGON Spoofing Vulnerability.
As a temporary workaround, consider restricting access to the NETLOGON service to minimize the risk of exploitation.
