CVE-2025-47726
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 · uneditedDelta Electronics CNCSoft lacks proper validation of the user-supplied file. If a user opens a malicious file, an attacker can leverage this vulnerability to execute code in the context of the current process.
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 confidenceDelta Electronics CNCSoft fails to properly validate user-supplied files before processing them. When a user opens a specially crafted malicious file, the lack of validation allows an attacker to achieve arbitrary code execution within the context of the application's running process, likely through unsafe deserialization or similar file parsing vulnerability.

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 CNCSoft installationSearch for CNCSoft in installed programs: Check Program Files (x86) for 'Deltaww' or 'CNCsoft' folder, or use 'Get-ItemProperty' in PowerShell at HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for display names containing 'CNCsoft' or 'Delta'Affected if CNCSoft is installed on the system
-
Determine installed versionOpen the CNCSoft application and navigate to Help > About, or locate the executable (typically in C:\Program Files (x86)\Deltaww\CNCSoft\) and right-click > Properties > Details to view the File VersionAffected if The reported version is 1.01.34 or lower (any version up to and including 1.01.34)
-
Identify vulnerable file handlingCheck if the application is configured to automatically open .cnc, .nc, or project files. Look for file associations in Windows: Right-click a .cnc or .nc file > Properties > Opens with, or check HKCR\.cnc and HKCR\.nc registry keysAffected if File associations exist for .cnc, .nc, or CNCSoft project files pointing to the vulnerable application
-
Inspect recent file activityReview the application's recent files list (typically in File > Recent within CNCSoft) or check Windows Jump Lists and recent documents for .cnc/.nc files that may have been openedAffected if There are recent .cnc, .nc, or project files opened by CNCSoft, indicating the vulnerable parsing code path is exercised
The system is affected if Delta Electronics CNCSoft version 1.01.34 or lower is installed and configured to open .cnc, .nc, or project files, as the lack of file validation occurs during the processing of these file types.

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 vendor-supplied patches for CNCSoft when available; avoid opening untrusted .cnc, .nc, or project files from unknown sources until the vulnerability is remediated.
