CVE-2021-22762
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 · uneditedA CWE-22: Improper Limitation of a Pathname to a Restricted Directory vulnerability exists inIGSS Definition (Def.exe) V15.0.0.21140 and prior that could result in remote code execution, when a malicious CGF or WSP file is being parsed by 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 · high confidenceA CWE-22 path traversal vulnerability in IGSS Definition (Def.exe) V15.0.0.21140 and prior allows remote code execution when the application parses malicious CGF or WSP files. The vulnerability stems from improper limitation of file path handling, enabling attackers to write files to restricted directories via specially crafted archive files.

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 IGSS Definition is installedLocate Def.exe on the system - typically found in the Schneider Electric IGSS installation directory (commonly C:\Program Files\Schneider Electric\IGSS\ or similar). Use file search or check Program Files.Affected if Def.exe exists on the system
-
Determine the installed version of IGSS DefinitionRight-click Def.exe, select Properties, then view the Details tab to find the File Version. Alternatively, right-click the file and select Properties > Version. Note the full version number.Affected if The reported version is 15.0.0.21140 or any version prior to it (e.g., 15.0.0.x where x is less than 21140, or earlier major versions)
-
Confirm IGSS Definition is configured to parse CGF or WSP filesCheck if the application has file association or import functionality enabled for .cgf and .wsp file extensions. Look for import settings in the IGSS Configuration or check if these file types are accepted by Def.exe.Affected if The application is configured to accept, import, or automatically parse CGF or WSP files from external or untrusted sources
-
Verify the service or application runs with elevated privilegesCheck the user account running the IGSS Def.exe process or service. In Windows Services (services.msc), find the IGSS service and check the Log On account. Also check file permissions on the IGSS directories.Affected if The IGSS Definition process runs with administrator privileges or has write access to system directories, which would allow the path traversal to write to restricted locations
The system is affected if IGSS Definition (Def.exe) version 15.0.0.21140 or earlier is installed and the application is configured to parse CGF or WSP files from external sources.

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 dataApply the vendor patch for IGSS Definition V15.0.0.21140 or later; until patched, implement file validation, disable automatic parsing of untrusted CGF/WSP files, and restrict file access controls.
