CVE-2018-7471
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 · uneditedKingView 7.5SP1 has an integer overflow during stgopenstorage API read operations.
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 confidenceInteger overflow vulnerability in KingView 7.5SP1 when handling stgopenstorage API read operations. The overflow occurs during storage object access, potentially allowing memory corruption or unexpected behavior when specially crafted data is processed.

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 KingView installation and versionCheck for KingView installation directory and locate the main executable (typically KingView.exe). Right-click the executable, select Properties, and examine the File Version or Product Version field.Affected if The installed version is KingView 7.5 (specifically SP1 or any 7.5.x release)
-
Confirm KingView service is runningOpen Windows Services (services.msc) or Task Manager and look for any KingView-related services or processes. Note the process name and running status.Affected if KingView service or process is actively running on the system
-
Verify stgopenstorage API exposureReview network exposure or project configurations that utilize the stgopenstorage API for storage object read operations. Check if the KingView runtime loads or accesses project files that may invoke this API.Affected if The system processes project files or external data through the stgopenstorage API functionality
-
Check for memory corruption indicatorsReview Windows Event Viewer application and system logs for any access violations, exception errors, or unexpected termination events related to KingView.exe or associated components.Affected if Event logs show recurring memory access violations or unexpected behavior tied to KingView processes
A system is affected if KingView 7.5 (specifically 7.5SP1) is installed and running, and the stgopenstorage API functionality is utilized for processing project data or external storage objects.

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 dataIsolate KingView systems on restricted network segments, minimize exposure to untrusted networks, and apply any vendor updates if available. Implement defense-in-depth controls around SCADA/HMI environments.
