CVE-2012-4711
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 · uneditedBuffer overflow in kingMess.exe 65.20.2003.10300 in WellinTech KingView 6.52, kingMess.exe 65.20.2003.10400 in KingView 6.53, and kingMess.exe 65.50.2011.18049 in KingView 6.55 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted packet.
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 confidenceBuffer overflow vulnerability in kingMess.exe component of WellinTech KingView SCADA/HMI software versions 6.52, 6.53, and 6.55 allows remote attackers to execute arbitrary code or cause memory corruption via specially crafted network packets.

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 versionLocate the KingView installation directory (commonly in Program Files or a vendor-specific path) and check for version information in the main executable or installation metadata. The version should be displayed as 6.52, 6.53, or 6.55.Affected if The installed KingView version is exactly 6.52, 6.53, or 6.55
-
Locate the kingMess.exe componentSearch for the file kingMess.exe within the KingView installation directory and verify it exists on the system.Affected if The kingMess.exe file is present in the KingView installation folder.
-
Verify service exposureCheck if the KingView service (typically running on ports associated with SCADA communications) is listening on network interfaces. Use netstat or similar tools to identify listening ports.Affected if The KingView service is accessible over the network (listening on non-loopback interfaces).
-
Confirm vulnerability trigger conditionReview whether the KingView communication service (kingMess.exe) is actively running and processing network packets.Affected if The kingMess.exe service is running and handling network communications.
A system is affected if it runs WellinTech KingView version 6.52, 6.53, or 6.55 with the kingMess.exe component present and 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 dataApply vendor patches if available; otherwise isolate affected systems via network segmentation and implement compensating controls given the critical CVSS score and ICS environment sensitivity.
