NVD · uneditedUnspecified vulnerability in JustSystems Ichitaro and Ichitaro Government allows remote attackers to execute arbitrary code via a crafted document, a different vulnerability than CVE-2010-3915.
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 confidenceA remote code execution vulnerability in JustSystems Ichitaro (Japanese word processor) allows attackers to execute arbitrary code by tricking users into opening a specially crafted malicious document file. The vulnerability is in document parsing/processing functionality.

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.
-
Verify if JustSystems Ichitaro is installedCheck Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Ichitaro', or look for Ichitaro.exe in typical installation directories such as C:\Program Files\JustSystems\Ichitaro or C:\Program Files (x86)\JustSystems\IchitaroAffected if Any Ichitaro installation is found on the system
-
Identify the installed Ichitaro versionRight-click on the Ichitaro executable (usually ichitaro.exe or similar) in the installation folder, select Properties, and check the Details tab for the File Version. Alternatively, query the Windows Registry for the Version value under the Ichitaro uninstall entryAffected if The version matches 2007, 2008, 2009, or cannot be determined (indicating an older or unpatched release)
-
Confirm document handling capability is enabledVerify that the Ichitaro document processing feature is functional by attempting to open a known benign .jtg or .jtd document file within the application. This confirms the parsing module is active and could process malicious filesAffected if Documents open successfully, indicating the parsing component is operational and exploitable
The user is affected if JustSystems Ichitaro is installed (regardless of version) and the document parsing functionality is available, since opening a specially crafted malicious document file can trigger remote code execution.

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 dataDo not open untrusted or unexpected Ichitaro document files. Apply vendor patches or update to the latest version of Ichitaro when available. Deploy endpoint anti-malware solutions that can detect malicious document files.
