Microsoft SharePoint Remote Code Execution Vulnerability

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 a remote code execution vulnerability in Microsoft SharePoint Server. An authenticated attacker could potentially execute arbitrary code on affected SharePoint servers by sending specially crafted requests. The CVSS 7.4 score indicates high severity with network-exploitable attack vector and moderate attack complexity.

MitigationApply Microsoft security updates for SharePoint Server as soon as possible. Restrict SharePoint server exposure to untrusted networks and follow least-privilege principles for SharePoint service accounts.

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 SharePoint Server installation
    Open SharePoint Management Shell and run: Get-SPFarm | Select-Object BuildVersion, Version, Products
    Affected if The Products field shows Microsoft SharePoint Server 2016 or 2019, or BuildVersion starts with 16.0 (indicating SharePoint 2016/2019)
  2. Check Windows Registry for exact SharePoint version
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Office\Server\16.0\BuildVersion (for 2016/2019)
    Affected if The BuildVersion value exists and corresponds to SharePoint 2016 or 2019 release builds
  3. Verify SharePoint services are running
    Open Services console (services.msc) and check if 'SharePoint Timer Service' and 'SharePoint Administration' services are running, or run Get-Service | Where-Object {$_.DisplayName -like '*SharePoint*'}
    Affected if SharePoint services are running, indicating an active SharePoint deployment that could receive malicious requests
  4. Check SharePoint web application exposure
    Open SharePoint Central Administration > Application Management > Manage web applications. Review which web applications are configured and their URLs
    Affected if Any SharePoint web applications are published and accessible on the network (even internally), as the vulnerability is network-exploitable

Your environment is affected if SharePoint Server 2016 or 2019 is installed and SharePoint web services are accessible on the network, regardless of authentication method.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
