Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SnapCenter versions 4.8 through 4.9 are susceptible to a vulnerability which may allow an authenticated SnapCenter Server user to become an admin user on a remote system where a SnapCenter plug-in has been installed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is an authenticated privilege escalation vulnerability in SnapCenter Server versions 4.8-4.9 where an authenticated user with standard SnapCenter privileges can elevate to admin-level access on remote systems where SnapCenter plug-ins are deployed, likely through improper validation of user permissions when executing remote operations.

MitigationUpgrade to a patched SnapCenter version beyond 4.9 and review user role assignments to ensure least-privilege principles are enforced for SnapCenter Server users.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify SnapCenter Server installation and version
    On the SnapCenter Server host, open the Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed applications and their versions. Look for 'NetApp SnapCenter Server' and note the version number.
    Affected if The installed version is 4.8, 4.8.x, 4.9, or 4.9.x (any version between 4.8 and 4.9 inclusive).
  2. Verify remote SnapCenter plug-in deployment
    In the SnapCenter GUI, navigate to the 'Hosts' or 'Plug-ins' section to view connected hosts and installed plug-ins. Alternatively, run 'Get-SmHost' and 'Get-SmPlugin' cmdlets in the SnapCenter PowerShell toolkit to enumerate hosts with plug-ins deployed.
    Affected if Remote hosts have SnapCenter plug-ins (such as SQL Server plug-in, Exchange plug-in, or file-system plug-in) installed and connected to the SnapCenter Server.
  3. Review SnapCenter user role assignments
    In SnapCenter GUI, go to 'Settings' > 'Users and Authentication' > 'Roles' to view defined roles. Check if any users or groups are assigned to roles other than 'SnapCenter Admin', such as 'Backup Operator' or custom roles with limited privileges. Run 'Get-SmUser' and 'Get-SmUserRole' cmdlets to enumerate users and their assigned roles.
    Affected if Non-admin users (those without SnapCenter Admin role) exist in the system and have authenticated access to SnapCenter.
  4. Confirm remote operation capabilities for standard users
    Attempt to trigger a remote operation (such as a backup or restore) on a remote plug-in host using a non-admin SnapCenter user account, or review audit logs in SnapCenter under 'Activity' > 'Audit Logs' for operations executed by standard users on remote plug-in hosts.
    Affected if Standard (non-admin) SnapCenter users can execute operations on remote plug-in hosts, which would indicate the vulnerable configuration is present.

You are affected if SnapCenter Server version 4.8 through 4.9 is installed, has remote plug-ins deployed to hosts, and contains non-admin users with authenticated access who can execute remote operations.

dbcve · scoped
Upgrade available Upgrade to a release after 4.9
Interim mitigation

Upgrade to a patched SnapCenter version beyond 4.9 and review user role assignments to ensure least-privilege principles are enforced for SnapCenter Server users.

Recommended fix Moderate confidence

SnapCenter version 4.10 or later

  1. Identify the current SnapCenter version by navigating to the SnapCenter GUI and checking the 'About' section or running 'Get-SmVersion' via SnapCenter PowerShell CLI
  2. Contact NetApp support or visit the NetApp Support Site at https://mysupport.netapp.com to obtain the latest SnapCenter version
  3. Upgrade SnapCenter Server to version 4.10 or later as this version addresses the privilege management vulnerability (CVE-2023-27316)
  4. After upgrading, verify that all SnapCenter plug-ins are compatible with the new version
  5. Test the upgrade in a non-production environment before deploying to production
Caveat Review NetApp release notes for version 4.10 to check for any configuration or workflow changes that may impact existing backup jobs or scripts
