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.
-
Check for Ichitaro 2006 installationOpen Windows Control Panel, navigate to Programs and Features (or Add/Remove Programs), and look for Justsystem Ichitaro 2006 in the list of installed software. Alternatively, search for the executable file (itaro2006.exe or similar) in the Program Files directory.Affected if Justsystem Ichitaro 2006 (any edition) appears in installed programs or the executable exists on the system
-
Identify the specific Ichitaro editionIn Programs and Features, note whether the entry shows 'Ichitaro 2006', 'Ichitaro 2006 Government Edition', or 'Ichitaro 2006 Trial Edition' to confirm it matches an affected version.Affected if The installed edition is 2006, 2006_government_edition, or 2006_trial_edition
-
Confirm document processing capabilityVerify that the Ichitaro application is functional and capable of opening document files by checking for the primary executable and associated document handlers in the installation directory.Affected if The application executable and document processing components are present and operational

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 dataUsers should upgrade to a patched version of Ichitaro if available, or migrate to an alternative word processing solution. Organizations should implement document filtering and warn users against opening documents from untrusted sources.
