Hi, We are running Exchange 2013 CU23. I have installed the May 2022 SU and prepared the domain as documented. When executing the latest Exchange Health Script it still says we are vulnerable "CVE-2022-21978 Install the May 2022 SU and run /PrepareDomain or /PrepareAllDomains - See: https://aka.ms/HC-May22SU". Someone had pointed out before that check for Exchange 2013 is not in place in the script ??
if ((($SecurityObject.MajorVersion -le [HealthChecker.ExchangeMajorVersion]::Exchange2016) -and
($SecurityObject.CU -le [HealthChecker.ExchangeCULevel]::CU23)) -or
(($SecurityObject.MajorVersion -eq [HealthChecker.ExchangeMajorVersion]::Exchange2019) -and
($SecurityObject.CU -le [HealthChecker.ExchangeCULevel]::CU12)) -and
($SecurityObject.ServerRole -ne [HealthChecker.ExchangeServerRole]::Edge)) {
Write-Verbose "Testing CVE: CVE-2022-21978"
