Virtual Administrator’s October 2022 Patch Recommendations


This month Microsoft released patches for 85 vulnerabilities with 15 rated “Critical” in severity.

All patches will be approved in our patch policy.


A sizable number (15) of critical patches this month but the big news is what Microsoft did not patch.

Two new zero-day vulnerabilities (CVE-2022-41040 and CVE-2022-41082) in Microsoft Exchange Server were reported at the end of September. Known as “ProxyNotShell” Microsoft has added protections to Exchange Online but on-prem Exchange Server administrators should review their Customer Guidance (See “Heads Up” below).

CVE-2022-41033 patches a publicly exploited zero-day “elevation of privilege” bug in the Windows COM+ event service. CVE-2022-41043 is a publicly disclosed flaw in Office for Mac which could lead to data leakage.

Organizations running Kubernetes clusters on Azure should patch for an Elevation of Privilege vulnerability (CVE-2022-37968). There is a known issue with Windows Group Policy preferences. This was actually introduced last month but was late to be acknowledged by Microsoft.

SharePoint Server also has some new known issues with this month’s patches. See “Know Issues” below. One new standalone SSUs for Windows 8.1/Server 2012 R2.


FYI Windows 11 version 22H2 available through Windows Update.

Microsoft Security Advisories


ADV990001 | Latest Servicing Stack Updates (Published:11/13/2018 | Last Updated:10/11/2022)

Reason for Revision: A Servicing Stack Update has been released for Windows 8.1/Server 2012 R2.


Known Issues

A couple known issues are listed below affecting all Windows systems and SharePoint Server.


Windows Group Policy Preferences

Affects all Windows versions

Copying files/shortcuts using Group Policy Preferences might not work as expected

Symptom: After installing this update, file copies using Group Policy Preferences might fail or might create empty shortcuts or files using 0 (zero) bytes. Known affected Group Policy Objects are related to files and shortcuts in User Configuration > Preferences > Windows Settings in Group Policy Editor.

Workaround: To mitigate this issue, you can do ONE of the following:

  • Uncheck the “Run in logged-on user’s security context (user policy option)”. Note: This might not mitigate the issue for items using a wildcard (*).
  • Within the affected Group Policy, change “Action” from “Replace” to “Update”.
  • If a wildcard (*) is used in the location or destination, deleting the trailing “\” (backslash, without quotes) from the destination might allow the copy to be successful.

Status: We are working on a resolution and will provide an update in an upcoming release.


SharePoint 2010 workflows

Affects SharePoint Server (Foundation 2013/Enterprise Server 2016/Server 2019/SharePoint Server Subscription Edition)

SharePoint 2010 workflows might be blocked by enhanced security policy (KB5020238)

Symptoms: After you install the following October security updates for Microsoft SharePoint Server, some Microsoft SharePoint 2010 workflow scenarios might be blocked. Additionally, “6ksbk” event tags are logged in SharePoint Unified Logging System (ULS) logs.

Cause: To strengthen its security, SharePoint supports only UTF-8 encoding for the workflow .xoml file.

Workaround: To work around this issue, modify your workflow .xoml file to use UTF-8 encoding, and then redeploy it.
