CVE-2018-10621
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 Delta Industrial Automation DOPSoft version 4.00.04 and prior utilizes a fixed-length stack buffer where a value larger than the buffer can be read from a .dpa file into the buffer, causing the buffer to be overwritten. This may allow remote code execution or cause the application to crash.
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 confidenceDelta Electronics DOPSoft versions 4.00.04 and prior contain a stack-based buffer overflow vulnerability triggered when parsing malicious .dpa files. The application reads a value larger than the fixed-length stack buffer can hold, causing overflow and allowing remote code execution or denial of service.

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.
-
Identify installed DOPSoft versionLocate the DOPSoft installation directory and check the file version information (typically in the executable properties or application About section). Common paths include C:\Program Files\Delta Industrial Automation\DOPSoft or similar. The executable is typically named DOPSoft.exe.Affected if The installed version is 4.00.04 or lower.
-
Confirm .dpa file parsing capability existsVerify that the DOPSoft application includes .dpa file import functionality. This is typically accessible through the application menu (File > Open or File > Import) and allows loading project or data files with .dpa extension.Affected if The application can open, import, or parse .dpa files.
-
Locate .dpa files on the systemSearch the system for .dpa files, particularly in user directories, shared folders, or the DOPSoft projects folder. Use file search or check recent documents/accessed files related to DOPSoft.Affected if Any .dpa files exist on systems running DOPSoft, especially from untrusted sources.
-
Assess network exposure of DOPSoft installationDetermine if the system running DOPSoft is accessible on the network or if the application is exposed to external connections. Check firewall rules and network segmentation around workstations with DOPSoft installed.Affected if DOPSoft is installed on a system directly accessible from the network or connected to untrusted segments.
You are affected if DOPSoft version 4.00.04 or lower is installed and the application has .dpa file parsing capability, particularly if .dpa files are processed or the system is network-accessible.

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 DOPSoft to a version beyond 4.00.04. If patching is not immediately feasible, restrict access to .dpa file import functionality and network exposure of systems running DOPSoft.
