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

Network File System RCE Repeat

Similar to last month's Patch Tuesday, the most critical vulnerability again lies in the Windows Network File System (NFS). A new remote code execution vulnerability, CVE-2022-26937, has been detected with a CVSS base score of 9.8. Microsoft's exploitability assessment also mentions that exploitation of this vulnerability is "More Likely". Attackers can exploit the vulnerability over the network by making an unauthenticated, specially crafted call to an NFS service to trigger a remote code execution.

Similar to last month, if you want to get a better view of which of your server have the NFS role installed, you can get a quick overview of all Windows Servers with the NFS role installed with the audit below.

Active Directory Services Elevation of Privilege

The second most critical vulnerability this month is in the Active Directory (AD) Domain. An authenticated user can exploit the vulnerability by manipulating attributes on computer accounts they have access to and acquire a certificate from Active Directory Certificate Services that allow elevation of privilege. Important to note is that you're only at risk if you have Active Directory Certificate Services running on your domain, again something you can easily find out by looking servers with the Active Directory Certificate Services role installed.

CVE-2022-26923 has a CVSS base score of 8.8 and, similar to the previous vulnerability, is also listed as "More Likely" to be exploited.

Remote Desktop Client RCE

Third on the list is a remote desktop client remote code execution vulnerability. Listed as CVE-2022-22017 with a CVSS base score of 8.8 this vulnerability can be exploited if an attacker convinces a user to connect to a malicious RDP server. Upon connecting, the malicious server could execute code on the victim's system in the user's context. As long as your access management is in order, even when exploited, the impact should be limited.

To help manage your update progress, we've created the Patch Tuesday Audit Report 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!
