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 checksWork through these to decide whether this CVE applies to you.
-
Determine installed Outlook versionOpen Outlook and navigate to Help > About Microsoft Outlook, or check the installed programs list in Windows Control Panel to identify the exact version numberAffected if The installed version is Microsoft Outlook 2000 or Microsoft Outlook 2002 specifically
-
Confirm HTML email format is enabledIn Outlook, go to Tools > Options > Mail Format and verify if HTML is selected as the message format for composing new messages, or check if incoming HTML emails are rendered rather than displayed as plain textAffected if HTML email format is enabled and Outlook renders HTML content in messages
-
Check email security zone settingsIn Outlook, go to Tools > Options > Security and examine the Security Zones settings to determine what content types are allowed to execute in emailsAffected if The security zone permits downloading or executing content from IFRAME elements in email messages
-
Inspect email attachment handling configurationCheck Outlook's attachment security settings under Tools > Options > Security to see if file download restrictions can be bypassed through embedded content like IFRAMEsAffected if Attachment handling allows IFRAME-based content to circumvent download restrictions
Your environment is affected if you are running Outlook 2000 or 2002 with HTML email rendering enabled and default security settings that permit IFRAME content execution in messages

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Microsoft security patches for Outlook 2002, disable HTML email rendering, and implement email filtering to block suspicious messages. Consider upgrading to a supported Outlook version as Outlook 2002 is end-of-life.
