Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Exchange Server is installedRun Get-ExchangeServer cmdlet in Exchange Management Shell or check Programs and Features for Microsoft Exchange ServerAffected if Exchange Server 2013, 2016, or 2019 is present on the system
-
Identify Exchange Server versionRun Get-ExchangeServer | Select-Object Name,AdminDisplayVersion in Exchange Management Shell, or check registry key HKLM\SOFTWARE\Microsoft\ExchangeServer\v15\SetupVersionAffected if Version matches 2013, 2016, or 2019 (any build)
-
Verify Exchange services are runningRun Get-Service *Exchange* | Where-Object {$_.Status -eq 'Running'} to confirm Exchange services are activeAffected if Exchange services are running and the server is operational
-
Confirm authenticated access is possibleReview who has valid mailbox accounts or Active Directory user accounts with Exchange server access using Get-Mailbox -ResultSize UnlimitedAffected if Any valid authenticated users exist in the Exchange environment
-
Check for applied security updatesReview installed updates for Exchange Server-specific security patches via Control Panel > View installed updates, or run Get-HotFix | Where-Object {$_.Description -like '*Exchange*'}Affected if No Exchange-specific security updates have been installed after October 2022
-
Assess network exposureReview firewall rules and IIS bindings to determine if Exchange services (OWA, ECP, EWS, MAPI) are exposed to untrusted networksAffected if Exchange web services are accessible from outside the trusted network
The system is affected if it runs Exchange Server 2013, 2016, or 2019 without the October 2022 or later security updates installed.
