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.
