We are primarily concerned with the three ‘Remote Code Execution’ threats that have CRITICAL severity levels. The 3 CRITICAL vulnerabilities that affect Windows Server 2012 are shared below.
|CVE Details||CVSS Score||Impact||Affected component||Description|
|CVE-2023-35385||9.8||CRITICAL||Microsoft Message Queuing||Successful exploitation of this vulnerability could allow an unauthenticated attacker to remotely execute code on the target server.|
|CVE-2023-36911||9.8||CRITICAL||Microsoft Message Queuing||Successful exploitation of this vulnerability could allow an unauthenticated attacker to remotely execute code on the target server.|
|CVE-2023-36910||9.8||CRITICAL||Microsoft Message Queuing||To exploit this vulnerability, an attacker would need to send a specially crafted malicious MSMQ packet to a MSMQ server. This could result in remote code execution on the server side.|
All these vulnerabilities will affect servers that run the Microsoft Messaging Queuing service. If the Message Queuing service is inactive or in a stopped state on the server, these threats will not have an impact on the said server.
Issue with Language Packs
If you install a language pack after installing the KB5029295 monthly rollup update on Windows Server 2012, you will need to redeploy the KB5029295 update.
Installing the language pack on top of the monthly rollup update renders the monthly rollup update infructuous.
Microsoft is working on resolving the issue. There is no ETA for the issue as of today.
