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 August 2023 edition of Patch Tuesday brings us 75 new fixes, with 6 rated as critical. We’ve listed the most important changes below.

⚡ TL;DR | Go Straight to the August 2023 Patch Tuesday Audit Report

Six Microsoft Exchange Vulnerabilities

Exchange is once again a hot topic this month. Coming in with four Remote Code Execution (RCE) vulnerabilities, a spoofing vulnerability, and an elevation of privilege vulnerability, it is likely the most important group of fixes this month. These vulnerabilities range between a CVSS base score of 8 and 9.8.

The two most severe in the group are CVE-2023-38182 and CVE-2023-35388, while they both “only” have a CVSS base score of 8, Microsoft mentions that these two are more likely to be exploited. In order to exploit these vulnerabilities, an authenticated attacker who is on the same intranet as the Exchange server can achieve remote code execution via a PowerShell remoting session.

Microsoft Teams Remote Code Execution

Two of the critical severity vulnerabilities are related to Microsoft Teams. Both are RCE vulnerabilities that require a user to join a malicious Microsoft Teams meeting set up by the attacker to be exploited. If exploited, the attacker can then execute code using the security context of that user.

Microsoft has released updates for all of its Teams versions. While Teams should automatically update (since Microsoft doesn’t allow manual deployment). However, it might be interesting to verify your Teams installations are fully up to date. Microsoft lists that it has updated its Teams applications to the following versions.

ProductBuild
Microsoft Teams for iOS5.12.1
Microsoft Teams for Mac1.6.00.17554
Microsoft Teams for Android1.0.0.2023070204
Microsoft Teams for Desktop1.6.00.18681

Run the Patch Tuesday August 2023 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 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!
