CVE-2020-27277
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 DOPSoft Version 4.0.8.21 and prior has a null pointer dereference issue while processing project files, 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 DOPSoft Version 4.0.8.21 and prior contains a null pointer dereference vulnerability triggered when parsing specially crafted project files. Although null pointer dereferences typically cause denial-of-service conditions, the CVSS description indicates potential for arbitrary code execution, suggesting the vulnerability may be exploitable under certain conditions.

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 DOPSoft installation and determine versionOpen DOPSoft and navigate to Help > About, or right-click the executable file and view Properties > Details. Alternatively, check the version listed in Add/Remove Programs.Affected if The reported version is 4.0.8.21 or lower (any version <= 4.0.8.21).
-
Identify if project files are processedConfirm whether DOPSoft is used to open, import, or parse .dop project files or similar configuration/project files supplied by external sources.Affected if The software parses project files, particularly those from untrusted sources, exposing the parsing code that contains the null pointer dereference flaw.
-
Assess file parsing code pathReview any available product documentation or contact Delta Electronics to confirm whether the project file parsing functionality contains the vulnerable code path. Observe if the application crashes when opening malformed project files.Affected if The installed version includes the vulnerable project file parsing routine and the application is used to process project files.
You are affected if DOPSoft version 4.0.8.21 or lower is installed and the software is used to open or parse project files, as the null pointer dereference is triggered during project file parsing.

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 patched version if available from Delta Electronics. Until then, avoid opening untrusted project files and restrict the software to isolated non-production environments, particularly in operational technology networks.
