dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify the Windows Server versionRun 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to confirm the system is Windows Server 2022Affected if The system is running any version of Windows Server 2022 with NFS enabled
-
Confirm NFS role is installedRun 'Get-WindowsFeature -Name *NFS*' in PowerShell or check via Server Manager to see if the NFS server role is installedAffected if The NFS Server role is installed on the system
-
Check if NFS services are runningRun 'Get-Service -Name *NFS*' in PowerShell or check the Services console for 'Server for NFS' and 'Client for NFS' servicesAffected if Any NFS-related services (NtfsSvc, NFSRdr) are in a Running state
-
Identify installed security updates for CVE-2022-34715Run 'Get-HotFix | Where-Object {$_.Description -match "Security Update"}' and search for updates released after August 2022, or check Windows Update history for CVE-2022-34715 related patchesAffected if No security update addressing CVE-2022-34715 has been installed (the system is missing the August 2022 or later security patch for this CVE)
A system is affected if it is Windows Server 2022 with the NFS role installed and running, and it is missing the CVE-2022-34715 security update.
