I recently applied the KB5000871 on Exchange Server 2013 servers to patch the Exchange vulnerabilities of March 2021. After this application, I had an issue with the ECP and OWA, it was no longer accessible. I know now this is a known issue and that it happened because I didn't run the update via an elevated cmd prompt.
Then, I ran the following scripts located in the Exchange installation folder : UpdateConfigFiles.ps1 and UpdateCAS.ps1. That solved the issue : the OWA and ECP were available again.
However, I have a question : does the application of these two scripts remove the benefits of the KB (as vulnerabilities mainly affect the OWA and ECP) ?
I need to be sure that the vulnerabilities are still fixed.
Is there a Microsoft Exchange expert who could answer me ?
Thank you a lot in advance,
