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
Mitsubishi E-Designer, Version 7.52 Build 344 contains five code sections which may be exploited to overwrite the heap. This can result in arbitrary code execution, compromised data integrity, denial of service, and system crash.

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

Heap corruption vulnerability in Mitsubishi E-Designer v7.52 Build 344 where five code sections allow heap memory overwrite, potentially enabling arbitrary code execution, data integrity compromise, DoS, or system crash.

MitigationUpgrade to a patched version of Mitsubishi E-Designer if available; if no patch exists, consider compensating controls such as network segmentation and restricting access to systems running this software.

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. Verify if Mitsubishi E-Designer is installed
    Check common installation directories such as C:\Program Files\Mitsubishi Electric\E-Designer or C:\Program Files (x86)\Mitsubishi Electric\E-Designer. Also check the Windows Programs and Features list (Add/Remove Programs) for any entry named 'Mitsubishi E-Designer' or similar.
    Affected if The software is found to be installed on the system.
  2. Determine the installed version of E-Designer
    Locate the executable (typically E-Designer.exe) and check its file properties by right-clicking the file, selecting Properties, then the Details tab. Look for the 'Product Version' or 'File Version' field.
    Affected if The version is listed as 7.52.
  3. Identify the specific build number
    In the same file properties Details tab, look for a 'Build' or 'Product Version' field that may contain a build number such as 344. Alternatively, launch E-Designer and check the About or Help > About dialog which often displays the full version and build.
    Affected if The build number matches 344 (indicating Build 344).

The system is affected if Mitsubishi E-Designer version 7.52 Build 344 is installed, as this specific version contains the heap corruption vulnerability in the five identified code sections.
