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
Microsoft Outlook 2000 and 2002, when configured to use Microsoft Word as the email editor, does not block scripts that are used while editing email messages in HTML or Rich Text Format (RTF), which could allow remote attackers to execute arbitrary scripts via an email that the user forwards or replies to.

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

Microsoft Outlook 2000 and 2002 when configured to use Microsoft Word as the email editor fails to block scripts embedded in HTML or Rich Text Format (RTF) email messages. When a user forwards or replies to such a malicious email, the embedded arbitrary script executes in the security context of the user's email client.

MitigationApply the relevant Microsoft security patch for this vulnerability, or disable the use of Microsoft Word as the email editor in Outlook, or disable script execution in Office applications.

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 installed Outlook version
    Open Outlook, click Help menu, select About Microsoft Outlook. Verify the version is 2000 (version 9.0) or 2002 (version 10.0).
    Affected if Version is 2000 or 2002
  2. Verify Word is configured as email editor
    In Outlook, go to Tools > Options > Mail Format tab. Under 'Compose in this message format' or 'Message format', check if 'Microsoft Word' is selected as the editor.
    Affected if Microsoft Word is selected as the email editor
  3. Check Office script execution settings
    In Windows Registry, check HKCU\Software\Microsoft\Office\<version>\Word\Security for 'AutomationSecurity' value, or in Word go to Tools > Macro > Security to see if macros/scripts are allowed to run.
    Affected if Script or macro execution is not set to High/Disabled for the Outlook/Word version
  4. Confirm email format handling
    In Outlook, go to Tools > Options > Mail Format tab. Check if HTML or Rich Text Format (RTF) is enabled as a message format.
    Affected if HTML or RTF message format is enabled and used as default

User is affected if running Outlook 2000 or 2002 with Microsoft Word configured as the email editor, and HTML/RTF emails with embedded scripts can be processed.
