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 2003, when configured to use Microsoft Word 2000 or 2003 as the e-mail editor and when forwarding e-mail, does not properly handle an opening OBJECT tag that does not have a closing OBJECT tag, which causes Outlook to automatically download the URI in the data property of the OBJECT tag and might allow remote attackers to execute arbitrary code.

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

In Outlook 2000/2003 configured to use Word as the email editor, forwarding emails containing malformed HTML with an opening OBJECT tag but no closing OBJECT tag causes Outlook to automatically retrieve and execute content from the URI specified in the data property. This silent automatic download and execution could allow remote attackers to run arbitrary code on the victim's machine.

MitigationDisable Microsoft Word as the email editor in Outlook, or apply available Microsoft security updates for affected Outlook/Word versions. Consider deploying email gateway filtering to block emails containing suspicious OBJECT tags.

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. Determine Outlook version
    Open Outlook, go to Help > About Microsoft Outlook, or check Add/Remove Programs for installed Microsoft Office components to confirm version is 2000 or 2003
    Affected if Version is exactly 2000 or exactly 2003
  2. Verify Word is the email editor
    In Outlook, go to Tools > Options > Mail Format tab, or Tools > Options > General tab (depending on version), and check if 'Use Microsoft Word to edit e-mail messages' is enabled
    Affected if Word is selected as the email editor in Outlook settings
  3. Identify email processing behavior
    The vulnerability triggers when forwarding or processing emails containing malformed HTML with an opening OBJECT tag but no closing OBJECT tag - inspect email headers or raw source of suspicious forwarded messages
    Affected if Emails containing incomplete OBJECT tags are being processed through Outlook with Word as the email editor

A user is affected if they run Outlook 2000 or 2003 with Word configured as the email editor and receive or forward emails containing malformed OBJECT tags in HTML.
