SP Build:
16.0.10400.20008 (Language independent CU)

SharePoint 2019 CU – KB articles describing the CU:

  • KB 5002423 – July 2023 Update for SharePoint Server 2019 (language independent)
  • No new language-dependent package was released for this CU. Use the latest available language CU: KB 5002403 (June 2023 CU).

SharePoint Server 2019 CU – CU download links:

After installation, remember to run the SharePoint 2019 Products Configuration Wizard or the following command:

PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important notes

Always install both packages in this order:

  1. language independent components (core CU for this release)
  2. language-dependent components (latest available language CU: KB 5002403, June 2023 CU)

For language-dependent packages, the language you select does not matter because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2019 farm, you must reinstall the language-dependent update afterwards.

Remember to keep Distributed Cache updated as well as SharePoint. See How to update Distributed Cache correctly (in Czech).

Included fixes and improvements

The following overview summarizes the fixes and improvements in this CU based on the official Microsoft KB articles.

SharePoint Server 2019

KB 5002423 addresses remote code execution, spoofing and security feature bypass vulnerabilities in SharePoint and SharePoint Server. The advisories are CVE-2023-33134, CVE-2023-33157, CVE-2023-33159, CVE-2023-33160, CVE-2023-33165.

The language-independent package KB 5002423 includes these SharePoint Server 2019 changes:

  • Fixes an issue where, after KB5002389 from May 9, 2023 is installed, updating or retracting a farm solution takes a long time when the farm service account belongs to the local Administrators group. Application pools can also remain stopped after the operation finishes.

  • Fixes an issue where application pools for non-SharePoint 32-bit applications on SharePoint servers stop responding when Enable 32-Bit Applications is set to True in IIS Manager.

  • Fixes an issue where keyboard focus cannot move to Save or Cancel in the Managed Metadata Service section.

  • Fixes an issue where the site avatar on modern pages of Chinese (Simplified) sites shows an abbreviated site type rather than the site’s actual title. To restore the previous behavior, run the following in the SharePoint Management Shell:

    $farm = Get-SPFarm
$farm.ServerDebugFlags.Add(53113)
$farm.update()
iisreset

  • Updates daylight saving time rules for time zones in Egypt, Fiji, Jordan, Mexico and Uruguay.

  • Adds every web application pool account to WSS_WPG on every server in the farm.
