CVE-2016-2290
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 · uneditedHeap-based buffer overflow in Pro-face GP-Pro EX EX-ED before 4.05.000, PFXEXEDV before 4.05.000, PFXEXEDLS before 4.05.000, and PFXEXGRPLS before 4.05.000 allows remote attackers to execute arbitrary code via unspecified vectors.
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 confidenceHeap-based buffer overflow vulnerability in Pro-face GP-Pro EX HMI software components (EX-ED, PFXEXEDV, PFXEXEDLS, PFXEXGRPLS) versions prior to 4.05.000 allows remote attackers to execute arbitrary code via unspecified vectors. The CVSS 8.8 score indicates network-exploitable code execution with low attack complexity.

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 GP-Pro EX productCheck Windows Add/Remove Programs or Program Files directory for Pro-face GP-Pro EX components (EX-ED, PFXEXEDV, PFXEXEDLS, PFXEXGRPLS)Affected if Any GP-Pro EX component is listed in installed programs
-
Retrieve installed version numberRight-click the main executable (typically in C:\Program Files\Pro-face\ or check version via file properties) and view Details tab to find the version, or run: wmic product where "name like '%GP-Pro%'" get name,versionAffected if Version cannot be determined or is not visible
-
Compare version against affected rangeIf version is visible, compare the first three octets (e.g., 4.0.4) against the affected range: any version <= 4.0.4 is vulnerableAffected if Installed version is 4.0.4 or lower (e.g., 4.0.0, 3.1.0, etc.)
-
Verify fixed version is not presentConfirm the installed version is NOT 4.05.000 or laterAffected if Version is 4.05.000 or later, indicating the patch has been applied
If any GP-Pro EX component (EX-ED, PFXEXEDV, PFXEXEDLS, PFXEXGRPLS) is installed at version 4.0.4 or lower, the environment is affected by this heap-based buffer overflow vulnerability.

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 all affected GP-Pro EX installations to version 4.05.000 or later. Prior to upgrade in production environments, validate backup/restore procedures and test HMI functionality in a staging environment to ensure operational continuity.
