CVE-2024-1941
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-B versions 1.0.0.4 and prior are vulnerable to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code.
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-B versions 1.0.0.4 and prior contain a stack-based buffer overflow vulnerability. The flaw allows an attacker to overflow a buffer on the stack, potentially overwriting return addresses or function pointers to achieve arbitrary code execution.

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.
-
Locate CNCSoft-B installation directoryCheck standard installation paths such as C:\Program Files\Delta Electronics\CNCSoft-B or C:\Program Files (x86)\Delta Electronics\CNCSoft-B, or use the Windows 'Programs and Features' control panel to find the installation.Affected if Cannot locate the software or its version information.
-
Identify installed version of CNCSoft-BIn the installation directory, look for version information in file properties (right-click the main executable, typically named CNCSoft.exe or similar, then select Properties > Details). Alternatively, in Windows 'Programs and Features', select the entry for CNCSoft-B and view the 'Version' column.Affected if The software is installed but version information is not accessible.
-
Compare version against affected rangeCompare the installed version number to 1.0.0.4. If the version is 1.0.0.4 or any version lower (for example, 1.0.0.3, 1.0.0.2, etc.), the installation is within the affected range.Affected if Installed version is 1.0.0.4 or lower.
-
Verify if CNCSoft-B is running or exposed on networkCheck running processes for CNCSoft-related executables, or scan the local network to see if the service is listening on any ports (common ports for industrial software include 80, 443, or 502). Use 'netstat -ano' to identify listening services.Affected if The vulnerable software is actively running and network-accessible.
You are affected if CNCSoft-B version 1.0.0.4 or earlier is installed and the software is running, as the stack-based buffer overflow can be exploited when processing input.

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 dataUpdate CNCSoft-B to a version newer than 1.0.0.4 when a patch is released by Delta Electronics. Until a patch is available, restrict network access to systems running this software and implement compensating controls such as network segmentation.
