Patch Tuesday is once again upon us. As always, our team has put together the monthly Patch Tuesday Report to help you manage your update progress. The audit report gives you a quick and clear overview of your Windows machines and their patching status. The October 2023 edition of Patch Tuesday brings us 104 new fixes, with 13 rated as critical. We’ve listed the most important changes below.
⚡ TL;DR | Go Straight to the October 2023 Patch Tuesday Audit Report
Microsoft Message Queuing Remote Code Execution Vulnerability
One of the most critical vulnerabilities lies in the Windows Message Queuing component. CVE-2023-35349 has a CVSS base score of 9.8 however in order to exploit the vulnerability, the Windows message queuing service must be installed. If the message queuing service is installed and an attacker exploits this vulnerability, it could allow an unauthenticated attacker to remotely execute code on the target server.
On top of the critical vulnerability, the MSMQ service had a total of 19 other vulnerabilities fixed! If you’re looking for an overview of all your servers that have the MSMQ service enabled, you can use our Windows Server MSMQ Server Feature Audit.
Layer 2 Tunneling Protocol RCE Vulnerabilities
A whopping nine vulnerabilities were fixed in the Layer 2 Tunneling Protocol, all with a CVSS base score of 8.1. All of them are rated as critical by Microsoft. However, an attacker needs to send a specially crafted protocol message to a Routing and Remote Access Service (RRAS) server to exploit the vulnerability.
Six SQL Server Vulnerabilities
A total of six vulnerabilities were fixed for SQL server. One Denial of Service vulnerability and five RCE vulnerabilities. For successful exploitation of the RCE, an attacker would have to trick an authenticated user into attempting to connect to a malicious SQL server via a connection driver.

To help manage your update progress, we’ve created the Patch Tuesday Audit that checks if the assets in your network are on the latest patch updates. The report has been color-coded to see which machines are up-to-date and which ones still need to be updated. As always, system administrators are urged to update their environment as soon as possible to ensure all endpoints are secured.
The Lansweeper Patch Tuesday report is automatically added to your Lansweeper Site. Lansweeper Sites is included in all our licenses without any additional cost and allows you to federate all your installations into one single view so all you need to do is look at one report, automatically added every patch Tuesday!
