CVE-2019-15638
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.

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 confidenceThe zenon Editor through version 8.10 contains an uncontrolled search path element vulnerability, allowing the application to load libraries from untrusted or user-controlled locations. This DLL hijacking flaw could enable an attacker to execute arbitrary code by placing malicious DLLs in directories the application searches when loading resources.

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 zenon Editor installation and versionOpen the zenon Editor application and navigate to Help > About, or check the program files directory for zenon (typically C:\Program Files\COPA-DATA\zenon 8.10 or similar). Locate the version information displayed in the application or in the executable properties.Affected if The installed version is 8.10 or any version lower than 8.10 (e.g., 8.00, 7.x, earlier releases).
-
Verify DLL search path vulnerability existsReview the application's behavior when launching. Use a process monitoring tool (such as Process Monitor from Sysinternals) to observe which directories the zenon Editor process searches when loading DLLs. Check if any user-writable directories (temp folders, user profiles, network shares) are in the search order before system directories.Affected if The application loads DLLs from directories that are writable by standard users or from locations outside the secure system directories (Windows\System32, program files directory).
-
Inspect application directory for unsigned or unexpected DLLsExamine the main zenon installation folder (typically under C:\Program Files\COPA-DATA\) for any DLL files that appear unexpected, have recent modification dates differing from the rest of the binaries, or are unsigned (right-click DLL > Properties > Digital Signatures tab). Compare against known legitimate zenon DLLs.Affected if Unexpected DLL files exist in the zenon installation directory, particularly if they are not digitally signed by COPA-DATA or were modified after the original installation date.
You are affected if the zenon Editor version is 8.10 or earlier and the application loads DLLs from user-writable or non-system directories during startup.

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 dataUpgrade to a patched version of zenon Editor beyond 8.10. In the interim, restrict file system permissions and ensure only trusted, signed binaries exist in directories within the application's search path.
