NVD · unedited
Untrusted pointer dereference in Microsoft Office allows an unauthorized attacker to execute code locally.

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

CVE-2025-24083 is an untrusted pointer dereference vulnerability in Microsoft Office that allows an unauthenticated attacker to execute arbitrary code locally on the target system. The vulnerability stems from improper validation of pointer references during Office document processing, which can be triggered by opening a specially crafted malicious Office file.

MitigationApply Microsoft security patches for CVE-2025-24083 immediately upon release. Until the patch is available, exercise caution with untrusted Office documents and consider disabling macros and OLE objects via Group Policy or Office Trust Center settings.

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 installed Microsoft Office product and version
    Open any Office application (Word, Excel, PowerPoint), go to File > Account > About [AppName] to view the version number. Alternatively, run 'Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Office\ClickToRun\Configuration -ErrorAction SilentlyContinue | Select-Object PlatformVersion,VersionToReport' in PowerShell for Click-to-Run installations, or check 'Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Office\*\Common\InstallRoot -ErrorAction SilentlyContinue' for MSI installations.
    Affected if The installed version matches Microsoft 365 Apps (any version), Office 2016, Office 2019, Office LTSC 2021, or Office LTSC 2024.
  2. Confirm Office document processing is active
    Check if Office applications are configured to open documents by default. Verify the presence of Office file handlers (.docx, .xlsx, .pptx) in the system registry under HKCR:\.docx\OpenWithProgids and similar keys, or check that Office applications launch without errors.
    Affected if Office applications are installed and capable of opening document files, making the vulnerability path viable.
  3. Verify macro and OLE object execution settings
    Open any Office application, go to File > Options > Trust Center > Trust Center Settings > Macro Settings or OLE Object Settings. Check whether macros can run or OLE objects can be inserted without user notification.
    Affected if Settings allow automatic or low-restriction execution of macros or OLE objects, which could amplify the impact of the pointer dereference flaw when a malicious file is opened.
  4. Check for recent Office security updates
    Open any Office application, go to File > Account > Update Options > View Update History. Look for any updates installed around the CVE disclosure date. Alternatively, check Windows Update history for installed Office security patches.
    Affected if No security update addressing CVE-2025-24083 has been installed, leaving the vulnerability unpatched.

If Microsoft Office (version 2016, 2019, 2021, 2024, or Microsoft 365 Apps) is installed without the CVE-2025-24083 security patch, the system is vulnerable when processing untrusted Office documents.
