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
An unauthenticated attacker can trick a local user into executing arbitrary commands by opening a deliberately manipulated project file with an affected engineering tool. These arbitrary commands are executed in the user context.

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 a command injection vulnerability in an engineering tool where the software fails to properly validate or sanitize project files. An unauthenticated attacker creates a malicious project file that, when opened by a local user, executes arbitrary commands in that user's context. The attack requires social engineering to convince the user to open the file.

MitigationUsers should not open project files from untrusted or unknown sources. Organizations should implement user awareness training about the risks of opening unverified files and consider application whitelisting as a defense-in-depth measure.

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. Identify if an engineering tool with project file support is installed
    Check system for engineering, CAD, or design software that uses project files (common extensions include .epj, .prj, .dsn, .sch, .vcxproj, .sln). Look in Program Files, Program Files (x86), or common application directories.
    Affected if The engineering tool is installed and processes project files
  2. Determine the installed version of the engineering tool
    Locate the application's executable (commonly in the install directory) and check its version property, or use the product's built-in About/Help > Version menu option. Compare the version number against any official vulnerability advisories from the vendor.
    Affected if The version matches the affected range listed in CVE-2025-41701 advisories (if published)
  3. Verify project file associations and double-click behavior
    Right-click a project file from this tool and check 'Open with' or inspect file association settings in the system. Confirm that opening the file launches the engineering application.
    Affected if Double-clicking a project file automatically opens it in the tool, enabling the attack vector
  4. Inspect user directories for untrusted project files
    Check Downloads, Desktop, and recent document folders for project files (.epj, .prj, .dsn, etc.) from unknown or untrusted sources. Use 'dir' or Get-ChildItem to list files with these extensions.
    Affected if The user has opened or currently holds malicious project files from untrusted sources
  5. Review application security settings for file validation
    If the engineering tool has a settings or preferences panel, look for options related to file validation, macro security, or script execution. Check if the application warns before executing embedded commands.
    Affected if File validation or security warnings are disabled or not present

You are affected if the engineering tool is installed, processes project files, and you have opened or may open project files from untrusted sources without proper validation safeguards enabled.
