PRTG support for CVE-2021-26414 mitigation

Microsoft is introducing changes in Windows to mitigate a vulnerability present in DCOM by default (ref "KB5004442 - Manage changes for Windows DCOM Server Security Feature Bypass (CVE-2021-26414)").

In June, manually enabling the vulnerability mitigation broke PRTG's WMI support. According to Microsoft's timetable, a Windows update in 2021-Q4 will see it enabled by default; another update due in 2022-Q1 will see it enabled permanently with no way to disable it.

Does the current stable version of PRTG support this? If not, does Paessler have a plan to implement the changes or provide a workaround?

Thank you

Hi there,

We already checked the change and it seems like that our WMI Sensors will still work with the latest Microsoft updates.

Confirmed - it looks like (one way or another) a PRTG update since June 2021 has resolved the problem.

Thanks
