Microsoft SharePoint Server Spoofing 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 spoofing vulnerability in Microsoft SharePoint Server. The vulnerability allows an attacker to impersonate legitimate users or entities within the SharePoint environment, potentially gaining unauthorized access to sensitive data or performing actions with elevated privileges.

MitigationApply the relevant Microsoft security update for SharePoint Server. If a patch is unavailable, implement compensating controls such as strict access controls, multi-factor authentication, and monitoring for suspicious SharePoint activity.

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. Confirm SharePoint installation
    Check if Microsoft SharePoint Server or SharePoint Foundation is installed on the server by reviewing installed programs in Control Panel > Programs and Features, or run 'Get-PnpDevice -Class Software | Where-Object {$_.FriendlyName -like "*SharePoint*"}' in PowerShell
    Affected if SharePoint Server or SharePoint Foundation is not found in the installed programs list, then the system is not affected by this vulnerability
  2. Identify SharePoint version
    Run 'Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\16.0\PID" | Select-Object Version, PID' for SharePoint 2016, or check the SharePoint Central Administration site under 'System Settings > Manage servers in this farm' to view the exact version number
    Affected if The installed version is SharePoint Foundation 2013, SharePoint Server 2016, or SharePoint Server 2019, indicating the system falls within the affected version range
  3. Check SharePoint build number
    Open SharePoint Central Administration, navigate to 'System Settings > Manage servers in this farm' and record the Build number (for example, 16.0.10310.5000 for SharePoint 2019 or 16.0.4999.5000 for SharePoint 2016)
    Affected if The build number is within the vulnerable build range for the detected version, as Microsoft security updates for this CVE modify the build number to a patched level
  4. Verify patch installation status
    Check Windows Update history or review installed updates via 'Get-HotFix | Where-Object {$_.Description -like "*SharePoint*"}' in PowerShell to see if security updates addressing CVE-2022-24472 have been applied
    Affected if No security update specifically addressing CVE-2022-24472 appears in the installed updates or hotfix list, meaning the vulnerability remains unpatched
  5. Review SharePoint authentication settings
    Navigate to SharePoint Central Administration > Application Management > Manage web applications > Authentication Providers to verify the enabled authentication methods (Windows, Forms, Claims, etc.)
    Affected if The SharePoint web applications are using authentication methods that rely on user impersonation features, which is the attack vector for this spoofing vulnerability

The environment is affected if SharePoint Server 2016 or 2019, or SharePoint Foundation 2013 is installed and the corresponding security update for CVE-2022-24472 has not been applied.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the relevant Microsoft security update for SharePoint Server. If a patch is unavailable, implement compensating controls such as strict access controls, multi-factor authentication, and monitoring for suspicious SharePoint activity.

Recommended fix High confidence

March 2022 Cumulative Update or later for your respective SharePoint version (2013 Foundation, 2016, or 2019)

  1. Identify your current SharePoint build version via SharePoint Management Shell: (Get-SPFarm).BuildVersion
  2. For SharePoint Foundation 2013: Install the March 2022 security update (KB5002082) or later cumulative update
  3. For SharePoint Server 2016: Install the March 2022 security update (KB5002091) or later cumulative update
  4. For SharePoint Server 2019: Install the March 2022 security update (KB5002086) or later cumulative update
  5. Verify the patch was applied by re-running: (Get-SPFarm).BuildVersion and confirming the version matches or exceeds the March 2022 release
Caveat Standard SharePoint CU installation requires downtime; test in staging environment before production deployment; ensure backup availability
