    This lets an Office document run code by abusing the ms-msdt: URI to launch the Microsoft Support Diagnostic Tool. What made it dangerous for phishing is that it can fire from the preview pane and does not need macros, so the user does not even have to enable content.

    Who is affected: Windows systems opening Office documents before the June 2022 fix.

    How to check: confirm the June 2022 cumulative update is installed. Note that some document formats could trigger this through the preview pane alone.

    Commonly flagged by: Nessus, Qualys, Microsoft Defender.

    Remediation · TruePositive EditorialCurated

    Install the June 2022 cumulative update, which fixed this. Before that patch, the mitigation was to back up and delete the ms-msdt URL handler from the registry. Where you do not need the diagnostic troubleshooters, you can disable that access by policy. Keep user awareness up for phishing.
