Windows Server 2012 and 2012 R2 End of Life

DirectAccess on Microsoft Windows

I want to remind you of a critical upcoming milestone that may affect your business. In just 60 days, we will reach the end of support for Windows Server 2012 and Windows Server 2012 R2. As of October 10, 2023, these operating systems will no longer receive security updates or technical support from Microsoft.

End of Support

End of support means your servers will be more vulnerable to security risks and potential threats. It is essential to take action now to ensure your IT infrastructure’s continued security and stability. Upgrading to newer, supported operating systems will protect your data and systems from potential cyber threats and provide access to enhanced features and performance improvements.

Don’t Wait

Now is the time to migrate those remaining workloads for those still running Windows Server 2012 and 2012 R2! Consider the following commonly deployed services that may still be running on Windows Server 2012 or 2012 R2 in your organization.

Remote Access – Windows Server Routing and Remote Access Service (RRAS) is commonly deployed to provide secure remote access for field-based workers. In addition, Absolute Secure Access (formerly NetMotion Mobility) is a widely implemented premium alternative to RRAS. Organizations may be hesitant to migrate these workloads because disrupting remote workers is painful.

DirectAccess – This remote access technology is widely deployed and extremely difficult to migrate. In addition, the complex nature of DirectAccess, with its many intricate interdependencies, poses a significant challenge to organizations migrating this role.

PKI – This is likely the most common enterprise service to be found running on Windows Server 2012 and 2012R2. Most organizations relying on Windows Active Directory Certificate Services (AD CS) to issue and manage enterprise certificates are reluctant to move this workload once it is deployed. This service is much easier to migrate than you might think! It can be done without disruption as well.

Consulting Services

We understand that upgrading might require careful planning and coordination, and our team is here to support you throughout the transition process. Don’t delay – take this opportunity to safeguard your organization’s data and systems by upgrading to the latest Windows Server version or exploring cloud-based solutions.

Always On VPN Windows 11 Status Indicator

Viewing the status of an Always On VPN connection has been challenging since the introduction of this technology. To see if an Always On VPN connection is active, users must proactively click on the network status icon in the system tray to view the current connection status. Optionally, users can use the Settings application in Windows and select the Network & Internet tab to view the Always On VPN connection status. Further, there were no options to see VPN status in the system tray natively if the user is using a consumer VPN such as Proton VPN.

New Status Indicator

Always On VPN administrators will be happy to hear that Microsoft recently introduced a new VPN status indicator for Windows 11. Beginning with the July 2023 cumulative update (KB5028185), users will begin to see a new network status icon (a small shield) on the network connectivity indicator on the system tray in Windows. Microsoft calls this new feature “glanceable VPN“.

Consumer VPN

While this new VPN status indicator is helpful for Always On VPN deployments, it is not limited to Always On VPN. The VPN status indicator will also display the lock icon in the system tray when the device is connected to any recognized VPN. The new VPN status indicator will include third-party enterprise VPN clients as well as some consumer VPNs.

Always On VPN July 2023 Security Updates

Hello, Always On VPN administrators! It’s the second Tuesday of the month, so you know what that means. Yes, it’s Patch Tuesday! This month’s security updates include several fixes for vulnerabilities potentially affecting Microsoft Always On VPN deployments.

RRAS Vulnerabilities

Microsoft’s July 2023 security updates include fixes affecting Windows Servers with the Routing and Remote Access Service (RRAS) role installed. Security vulnerabilities CVE-2023-35365, CVE-2023-35366, and CVE-2023-35367 are all Remote Code Execution (RCE) vulnerabilities with a Critical security rating and a CVSS score of 9.8. These security vulnerabilities in Windows Server RRAS are particularly troublesome due to the nature of the workload. RRAS servers are, by design, exposed to the public Internet. Although there are no known exploits in the wild at this time, this attack requires no special privileges other than network access. Administrators running Windows Server with RRAS installed are encouraged to update as soon as possible.

AD CS Vulnerabilities

Most Always On VPN implementations leverage enterprise PKI certificates for user and device authentication. Administrators commonly deploy Microsoft Active Directory Certificate Services (AD CS) to support this. This month there are two security vulnerabilities in AD CS marked as Important. CVE-2023-35350 and CVE-2023-35351 address RCE vulnerabilities that exploit a race condition on the server. However, AD CS servers are not exposed to untrusted networks. In addition, attackers would require administrative rights on the server to exploit these vulnerabilities.

Network Load Balancing

Finally, of importance to Always On VPN administrators using Windows Network Load Balancing (NLB) to provide load balancing for their RRAS servers, there is a vulnerability in the NLB service. CVE-2023-33163 addresses an RCE vulnerability in NLB identified as Important.
