January 2023 CU for SharePoint Server 2019 is available for download

The product group released the January 2023 Cumulative Update for SharePoint Server 2019 product family. SharePoint Server 2019 is patched with a language dependent and a language independent fix.

The KB article for January 2023 CU will be available at the following Location in a couple of hours:

  • KB 5002329 – January 2023 Update for SharePoint Server 2019 (language independent)
    This is also a security update!
  • There was no language dependent fix released this month.
    The most recent language dependent fix is KB 5002310 from December 2022 CU.

The downloads for January 2023 CU are available through the following links:

Important: It is required to install both fixes (language dependent and independent) to fully patch a SharePoint server. This applies also to servers which do not have language packs installed. The reason is that each SharePoint installation includes a language dependent component together with a language independent component. If additional language packs are added later (only) the language dependent fix has to be applied again.

It is irrelevant which language you pick on the drop down in download center. Even the language dependent fixes are all in the same package for all languages.

After installing the fixes you need to run the SharePoint 2019 Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct options.

Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

 
SharePoint 2019 January 2023 CU Build Number:

  1. Hi Stefan, do you have any updates regarding CVE-2023-21743? Don’t know if your blog is also covering this, but just wanted to make you and others aware.

  2. Hi Stefan

    Do you have any updates about the issue with subscription database getting status “Database is too old and upgrade is required” after installation of this CU ?

    I got it first time after installing CU November 2022 (I see people are getting this issue since CU for October 2022). Last time, after installing CU November 2022, we fixed it by granting the sp farm user db_owner on the subscription db it was complaining about. Now we get the same issue again after installing CU for January 2023.

    Any ideas what is causing this issue and how to fix it permanently ?

    1. Hi Adeel,
      we haven’t been able to reproduce this issue inhouse.
      If you have a system that shows that problem I would recommend to open a support case with Microsoft.

      1. Probably running PSCONFIG.exe again will solve it.

        PowerShell command: PSCONFIG.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

        We had the same issue last updates. First the DB wasn’t available (I forgot the exact message -> Not Responding or something like that). We solved that by granting the farm admin account DB owner permissions on the specific DB as you already did. Then “Database is too old and upgrade is required” appeared. That was solved after running the PSCONFIG.exe again. When it isn’t solved, check the logs of the PSCONFIG which are mostly stored in ..\SharePoint\ULSLog

        1. For other DBs
          Get-SPContentDatabase | Upgrade-SPContentDatabase
          Then run psconfig

        2. Thanks for the tips. Nothing alarming in the log. Got this. “database SubscriptionSettingsDatabase_ updated, needsRefresh”.

          Running the config wizard without granting db_owner to farm-account did no help. In the end we resolved the issue like the last time we got it: grant sp farm-account db_owner on Subscription Settings db, and run the config wizard again.

  3. Any reason to change the build numbering ? Or was the 2nd for DEC a typo?
    Like this is is not possible to easy check the build using F12, response headers MicrosoftSharePointTeamServices: 16.0.0.10394

    JAN23 Language independent fix: 16.0.10394.20021 should be 10394 or 10395
    DEC22 Language independent fix: 16.0.10394.20016 should have been 10393
    DEC22 Language dependent fix: 16.0.10393.20000

    1. Hi Roel,
      the original Dec CU fix was 10393. The rereleased one has 10394.20016 as the work on Jan CU had already started.
      Cheers,

      1. Check on that. But that means we have no way to check using F12 on the actual build of the farm. We are still looking at the issue that the documentID has gone from the InfoPanel.

        1. This method is not reliable as it relies on a custom http header which is set by one one of the packages of the CU.
          We also see frequently that this header is not updated when installing patches.

  4. Hi Stefan,
    we skipped previous update (december 2022 CU), can you tell me if with this we need to apply the KB4461512 too or just the dependent language from december 2022 CU?

    Reply

    1. Hi Mirko,
      if you are installing KB5002329 then there is no need to install KB4461512.
      Cheers,

      1. Hi Stefan,

        just to be clear, it is safe to install this months CU KB5002329 with last months KB5002310 language dependent Update if we skipped december?

        Thanks and best regards
        Tristan

        1. Hi Tristan,
          Yes that is the correct method.

    1. Hi Bikram,
      yes these are the most current patches.
      Install both of them and run the config wizard and your system will be fully patched.
