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
The SMBv1 server in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607; and Windows Server 2016 allows remote attackers to execute arbitrary code via crafted packets, aka "Windows SMB Remote Code Execution Vulnerability." This vulnerability is different from those described in CVE-2017-0143, CVE-2017-0144, CVE-2017-0145, and CVE-2017-0148.

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 · high confidence

Remote code execution vulnerability in the SMBv1 server allowing arbitrary code execution via crafted packets. This is part of the same SMB exploit family as EternalBlue, exploitable over the network without authentication.

MitigationApply Microsoft security update MS17-010 to patch the vulnerability, or disable SMBv1 protocol entirely if not required for business operations.

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. Check if SMBv1 is enabled on Windows systems
    Run 'Get-WindowsOptionalFeature -Online -FeatureName SMB1Protocol' in PowerShell, or check registry key 'HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\SMB1' (value 0 means disabled, 1 means enabled)
    Affected if SMBv1 is enabled (feature state is 'Enabled' or registry value is 1)
  2. Identify Siemens Acuson P300 firmware version
    Access the device system information or firmware update settings, or consult device documentation/service interface
    Affected if Firmware version equals 13.02, 13.03, 13.20, or 13.21
  3. Identify Siemens Acuson P500 firmware version
    Access the device system information or firmware update settings, or consult device documentation/service interface
    Affected if Firmware version equals va10 or vb10
  4. Identify Siemens Acuson Sc2000 or Syngo Sc2000 firmware version
    Access the device system information or firmware update settings, or consult device documentation/service interface
    Affected if Firmware version is between 4.0 and 4.0e (inclusive), or equals 5.0a
  5. Identify Siemens Acuson X700 firmware version
    Access the device system information or firmware update settings, or consult device documentation/service interface
    Affected if Firmware version equals 1.0 or 1.1
  6. Identify Siemens Tissue Preparation System or Versant Kpcr Molecular System firmware version
    Access the device system information or firmware update settings, or consult device documentation/service interface
    Affected if Any firmware version present (all versions affected)

A system is affected if SMBv1 is enabled on Windows, or if any Siemens device listed matches the specific firmware versions or is a Tissue Preparation System or Versant Kpcr Molecular System of any version.

Interim mitigation

Apply Microsoft security update MS17-010 to patch the vulnerability, or disable SMBv1 protocol entirely if not required for business operations.

Recommended fix High confidence

Apply Microsoft MS17-010 security update; for Windows 10/Server 2016, upgrade to versions beyond 1607 which have cumulative security updates

  1. Apply Microsoft Security Bulletin MS17-010 to address the SMBv1 vulnerability on affected Windows systems (Vista SP2, Server 2008 SP2/R2 SP1, Windows 7 SP1, 8.1, Server 2012/R2, RT 8.1, Windows 10 1507/1511/1607, Server 2016)
  2. If patching is not immediately feasible, disable SMBv1 by following Microsoft guidance: Run 'Set-SmbServerConfiguration -EnableSMB1Protocol $false' on PowerShell for Windows 8/Server 2012 and later, or via Registry for older systems
  3. For Acuson P300, P500, X700, Syngo Sc2000, Tissue Preparation System, and Versant Kpcr Molecular System devices, contact Siemens Medical Solutions for device-specific firmware updates or remediation guidance
  4. Verify SMBv1 is disabled using 'Get-SmbServerConfiguration | Select-Object EnableSMB1Protocol'
  5. Apply the patches and confirm remediation through vulnerability scanning
Caveat Ensure compatibility testing before deploying patches in production environments; some legacy systems may depend on SMBv1
