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 FieldList ActiveX control in the Microsoft Access Wizard Controls in ACCWIZ.dll in Microsoft Office Access 2003 SP3 does not properly interact with the memory-access approach used by Internet Explorer and Office during instantiation, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via an HTML document that references this control along with crafted persistent storage data, aka "ACCWIZ.dll Uninitialized Variable 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 · high confidence

This is an uninitialized variable vulnerability in the FieldList ActiveX control (ACCWIZ.dll) within Microsoft Office Access 2003 SP3. Attackers can exploit this by crafting an HTML document that references the control combined with malicious persistent storage data, leading to memory corruption and potential remote code execution.

MitigationApply Microsoft security updates for this vulnerability, or upgrade from Office 2003 to a supported version. As a compensating control, disable ActiveX controls in Internet Explorer and Office for high-risk systems.

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 Microsoft Access 2003 installation
    Check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\11.0\Access\InstallRoot or verify presence of Microsoft Access 2003 in Add/Remove Programs
    Affected if Microsoft Access 2003 is installed on the system
  2. Locate the vulnerable ACCWIZ.dll component
    Search for ACCWIZ.dll in the Office installation directory (typically C:\Program Files\Microsoft Office\ or C:\Program Files (x86)\Microsoft Office\) and check the file version properties
    Affected if ACCWIZ.dll exists and its version corresponds to Access 2003
  3. Verify the FieldList ActiveX control is registered
    Check Windows registry under HKLM\SOFTWARE\Classes\TypeLib or HKCR\TypeLib for the FieldList control GUID, or use regsvr32 to query ACCWIZ.dll registration status
    Affected if The FieldList ActiveX control (CLSID {03C9C4A4-6D43-11D3-A6D1-00C04F8EFB6E}) is registered on the system
  4. Determine if ActiveX controls are enabled
    Check Internet Explorer security settings (Tools > Internet Options > Security > Custom Level) for 'Initialize and script ActiveX controls not marked as safe' setting, or check Office Trust Center ActiveX settings
    Affected if ActiveX controls are permitted to run in the browser or Office applications

A system is affected if Microsoft Access 2003 is installed, ACCWIZ.dll is present, the FieldList ActiveX control is registered, and ActiveX execution is enabled in the targeted environment.
