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
Electronic Deliverables Creation Support Tool (Construction Edition) prior to Ver1.0.4 and Electronic Deliverables Creation Support Tool (Design & Survey Edition) prior to Ver1.0.4 improperly restrict XML external entity references (XXE). By processing a specially crafted XML file, arbitrary files on the system may be read by an attacker.

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

This is an XXE (XML External Entity) vulnerability in the Electronic Deliverables Creation Support Tool. The application improperly restricts XML external entity references when processing XML files, allowing attackers to craft malicious XML that can read arbitrary files from the server's filesystem.

MitigationUpgrade to version 1.0.4 or later for both the Construction Edition and Design & Survey Edition of the tool. If upgrading is not immediately possible, configure the XML parser to disable external entity processing.

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. Locate the Dfeg Electronic Deliverables Creation Support Tool installation
    Search for the application executable or installation directory on the system, typically found in Program Files or application-specific directories
    Affected if The tool is installed and used for processing XML-based deliverables
  2. Identify the installed version of the tool
    Right-click the application executable, select Properties, and check the Version tab, or use the application's Help > About menu to display version information
    Affected if The displayed version number is lower than 1.0.4 (for example, 1.0.3, 1.0.2, etc.)
  3. Verify XML file processing capability
    Open the application and attempt to import or open an XML file using the tool's standard file import or open functionality
    Affected if The tool successfully parses and loads XML files, indicating XML processing is enabled
  4. Check XML parser configuration for external entity settings
    Locate the application's configuration files (typically XML, properties, or settings files in the installation directory) and search for XML parser-related settings such as 'external-entities', 'xxe', or 'dtd' processing options
    Affected if External entity processing is not explicitly disabled or set to false in the parser configuration

A user is affected if the Dfeg Electronic Deliverables Creation Support Tool is installed with a version lower than 1.0.4 and the application processes XML files with external entity processing enabled in the parser settings.

Upgrade available Upgrade to 1.0.4 or later
Fixed in 1.0.4
Interim mitigation

Upgrade to version 1.0.4 or later for both the Construction Edition and Design & Survey Edition of the tool. If upgrading is not immediately possible, configure the XML parser to disable external entity processing.

Recommended fix High confidence

1.0.4 or later

  1. Obtain Electronic Deliverables Creation Support Tool version 1.0.4 or later from the official vendor source (www.dfeg.mod.go.jp)
  2. Follow the vendor's standard upgrade/installation procedure for the Construction Edition or Design & Survey Edition as applicable
  3. After upgrading, verify the installed version is 1.0.4 or later to confirm the vulnerability is resolved
