back to article Microsoft takes another run at closing Exchange brute-force security hole

Microsoft has issued a fresh update to address an old vulnerability affecting Exchange Server 2019 and 2016 while its online service has problems of its own. According to Microsoft, the update is another attempt at fixing CVE-2023-21709, an elevation-of-privilege vulnerability with a relatively straightforward exploitation …

    Hope springs eternal

    Given that everything old comes back again, I can't wait for all this Online malarky to be folded back into local servers.

    Because I dearly hope that CxOs will tire of relying on Borkzilla's ceaselessly failing infrastructure.

    Maybe they'll even go for something else entirely. There has to be something else than Exchange in this world, no ?

    Please ?

      You need to come up with a catchy name first, some sort of "local cloud" pun.

      "Run your own Drizzle server" or something like that.

        I think they call it “Edge computing”?

      Hopefully someone will need my Lotus Domino and Notes skills before I completely forget them. R5 was almost usable by end users.

        I always considered it a shame that people were happy to write really complex applications for their business needs but would use the sample user mail template 'out of the box' and then whinge it was too clumsy/ugly.....Well write your own then, it is actually very very simple

    The service health pages in M36x are reporting that the issue has now been resolved.

    And on the subject of Patch Tuesday emissions, has anyone else noticed that this month's has delivered some nag icons to Windows Server 2022 - start menu and system tray - to try to get you to enrol the devices in Azure Arc?

    So far as I can see it is only the 2022 version (not 2016 and 2019), and the icons only appear if the Windiws instance is running on-prem (bare meta or VM). Doesn't appear in Azure VMs, as would be expected. No idea what happens with those on other cloudy platforms.

      Is that in the Security Only updates?

        Not actually sure - I didn't check which specific update dumped it there, other than that it was one of this Tuesday's batch.

          Just to add, looks like it's this one:

            Remove-WindowsFeature AzureArcSetup

            followed by a reboot seems to take care of it.

              Yeah, it does - I've just been testing as well!

      "Microsoft, in its note on the issue, said the root cause of the outage was: "A recent service update, applied to a section of infrastructure responsible for enforcing IP address anti-spam rules, contains a change which is inadvertently causing impact."

      Make of that what you will, and the use of the word "inadvertently."

      "Inadvertently" - Another anonymous MS Engineer applied another Powershell script he shouldn't have. Why have on-prem where you can run your own systems in a stable manner when you can pay Microsoft to f*** up your core contact with clients monthly?

        A recent service update, recent code change, etc - nearly every day there are advisories like this from MS!
