CVE-2012-4714
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 · uneditedInteger overflow in RNADiagnostics.dll in Rockwell Automation FactoryTalk Services Platform (FTSP) CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 allows remote attackers to cause a denial of service (service outage or RNADiagReceiver.exe daemon crash) via UDP data that specifies a large integer value.
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 confidenceInteger overflow vulnerability in RNADiagnostics.dll in Rockwell Automation FactoryTalk Services Platform allows remote attackers to cause denial of service by sending specially crafted UDP packets containing large integer values. The overflow triggers a crash of the RNADiagReceiver.exe daemon, resulting in service outage.

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.
-
Verify FactoryTalk Services Platform installationCheck for FactoryTalk Services Platform installation in Windows Programs and Features or review installation directories (typically C:\Program Files\Rockwell Software\FactoryTalk Services Platform or similar)Affected if FactoryTalk Services Platform version cpr9 is installed
-
Confirm installed version is CPR9Right-click on the installed FactoryTalk Services Platform entry in Programs and Features, select Properties, and verify the version shows 'cpr9' in the version fieldAffected if Installed version is exactly cpr9 (other versions are not affected by this specific CVE)
-
Locate RNADiagReceiver.exe serviceOpen Windows Services console (services.msc) and search for RNADiagReceiver service, or check Task Manager for RNADiagReceiver.exe process runningAffected if RNADiagReceiver.exe service or process is present and running on the system
-
Check UDP listener status for RNADiagnosticsUse netstat -ano command to list UDP ports in listening state, particularly ports associated with RNADiagReceiver service (consult FactoryTalk documentation for default UDP port, typically in the 4445-4446 range for RNA services)Affected if The system is listening on UDP ports used by the RNADiagReceiver service and is network-accessible
A system is affected if it has FactoryTalk Services Platform version cpr9 installed with the RNADiagReceiver service running and exposing UDP listeners to network traffic.

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 available vendor patches for FactoryTalk Services Platform CPR9 versions. If no patch is available, implement network segmentation to restrict UDP traffic to the affected service and monitor for anomalous UDP traffic targeting the RNADiagReceiver service.
