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.
-
Check installed Exchange Server versionOpen Exchange Management Shell and run: Get-ExchangeServer | Format-List Name, AdminDisplayVersion, ExchangeVersion. Or check Control Panel > Programs > Microsoft Exchange Server for the exact version number.Affected if The version matches Exchange Server 2013, 2016, or 2019 (any build of these major versions)
-
Verify Exchange services are runningIn Exchange Management Shell, run: Get-Service *Exchange* | Where-Object {$_.Status -eq 'Running'} to confirm Exchange services are active.Affected if Exchange services are running on an affected version listed above
-
Check for applied security updatesIn Exchange Management Shell, run: Get-ExchangeServer | Get-ExchangeServerUpgradeInformation or check installed Windows updates for the November 2022 security patch (KB5019758 or subsequent updates).Affected if The November 2022 security updates have not been installed on an affected Exchange version
-
Confirm Exchange Server is exposed to networkVerify the Exchange servers are internet-facing or accessible from untrusted networks by reviewing firewall rules and IIS bindings: Get-WebBinding -Protocol https in IIS Manager.Affected if Exchange services (particularly OWA, ECP, or EWS) are externally accessible without proper filtering
A system is affected if it runs any version of Microsoft Exchange Server 2013, 2016, or 2019 and lacks the November 2022 security updates, with the vulnerable services exposed to potential attackers.
