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
A CWE-787: Out-of-bounds Write vulnerability exists in IGSS Definition (Def.exe) version 14.0.0.20247, that could cause Remote Code Execution when malicious CGF (Configuration Group File) file is imported to IGSS Definition.

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

A CWE-787 out-of-bounds write vulnerability exists in IGSS Definition (Def.exe) version 14.0.0.20247. The vulnerability is triggered when importing a malicious CGF (Configuration Group File) file, allowing an attacker to write data beyond allocated buffer boundaries and achieve remote code execution.

MitigationAvoid importing untrusted or unverified CGF files into IGSS Definition. Apply vendor patches when available and implement file validation/sanitization for CGF imports until the vulnerability is remediated.

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 IGSS Definition executable
    Search for Def.exe in typical installation directories such as C:\Program Files\Schneider Electric\IGSS\ or use system file search to find the executable
    Affected if Def.exe is not found on the system, the vulnerability does not apply
  2. Determine installed version of Def.exe
    Right-click Def.exe, select Properties, then view the Details tab to read the File Version field. Alternatively, run 'powershell (Get-Item "C:\Path\To\Def.exe").VersionInfo' to retrieve version information
    Affected if The reported version is 14.0.0.20247 or any lower version number (versions <= 14.0.0.20247)
  3. Confirm CGF import capability exists
    Launch IGSS Definition and navigate the menu to locate the import function for CGF (Configuration Group File) files, typically found under File or Project menu options
    Affected if The CGF import feature is present and accessible in the application interface
  4. Assess exposure to untrusted CGF files
    Identify whether the system allows or has historically imported CGF files from external or untrusted sources, or is configured to process CGF files from network locations accessible to untrusted users
    Affected if The system can import CGF files from sources that are not verified as trusted

You are affected if IGSS Definition (Def.exe) version 14.0.0.20247 or lower is installed AND the CGF file import feature is accessible and could process an untrusted or malicious CGF file.

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 data
Upgrade available Upgrade to a release after 14.0.0.20247
Interim mitigation

Avoid importing untrusted or unverified CGF files into IGSS Definition. Apply vendor patches when available and implement file validation/sanitization for CGF imports until the vulnerability is remediated.
