Microsoft-Patch-Tuesday-May-2022

Patch Tuesday is once again upon us. The December 2022 edition of Patch Tuesday brings us 56 fixes, with 6 rated as critical. We’ve listed the most important changes below.

⚡ TL;DR | Go Straight to the December 2022 Patch Tuesday Audit Report

PowerShell Remote Code Execution Vulnerability

The most severe issue addressed this month is a Powershell RCE vulnerability. With a CVSS score of 8.5 CVE-2022-41076 doesn’t quite have the highest score of the month, but the combination of a relatively high score and the remark from Microsoft that it is more likely to be exploited makes it the top of our list.

According to Microsoft, any authenticated user could trigger this vulnerability and no admin or other elevated privileges are required. Once exploited an attacker can run unapproved commands on the target system. The main reason why this vulnerability isn’t more critical is because “additional actions prior to exploitation to prepare the target environment” are needed.

Microsoft SharePoint Server RCE

The second RCE vulnerability to highlight this month is related to Sharepoint. Sharepoint has been getting more attention lately with Microsoft fixing more severe security issues. This month CVE-2022-44693 and CVE-2022-44690 have been fixed, both having a CVSS base score of 8.8. When exploited, the vulnerability allows an authenticated attacker with Manage List permissions could execute code remotely.

Microsoft Exchange Server Spoofing Vulnerability

Lastly, we’re returning to Exchange, a hot topic for the last couple of months. Last month CVE-2022-41079 and CVE-2022-41078, that both have a CVSS 8.0, allow the disclosure of NTLM hashes when exploited. The attacker does have to be authenticated. Regarding the attack vector, Microsoft added the following clarification this month:

This vulnerability’s attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require man-in-the-middle type setups or that rely on initially gaining a foothold in another environment.

Run the Patch Tuesday December 2022 Audit

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 Lansweeper Cloud sites. Lansweeper Cloud 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!
