CVE-2014-2342
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 · uneditedTriangle MicroWorks SCADA Data Gateway before 3.00.0635 allows remote attackers to cause a denial of service (excessive data processing) via a crafted DNP3 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 confidenceTriangle MicroWorks SCADA Data Gateway versions before 3.00.0635 are vulnerable to a denial of service attack. Remote attackers can send crafted DNP3 packets that trigger excessive data processing, causing the gateway to become unavailable.

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 if Triangle MicroWorks SCADA Data Gateway is installedCheck program files or application directories for 'Triangle MicroWorks' or 'Scada Data Gateway' folders. On Windows, review installed programs via Control Panel > Programs and Features or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion'Affected if The application is present on the system
-
Determine the installed versionLocate the version information in the application directory, registry keys, or by right-clicking the executable and selecting Properties > Details. Common locations include the main gateway executable or a versioninfo file within the application folderAffected if The version number matches any of the affected versions: <= 3.00.0633, or specifically 2.50, 2.50.0309, 2.51, 2.53, 2.54.0515, 2.54.0516, 2.54.0517, 2.54.0518, 2.54.0528, 2.54.0529, or 2.54.0536
-
Verify DNP3 protocol handling is enabledReview the gateway configuration files or management interface for DNP3 listener/service settings. Check if the gateway is configured to accept DNP3 connections on the configured ports (typically UDP/TCP port 20000)Affected if DNP3 protocol processing is enabled and the gateway is listening for DNP3 traffic
-
Assess network exposure of the DNP3 serviceReview firewall rules and network ACLs to determine if the DNP3 ports (default 20000) are accessible from untrusted networks. Use 'netstat -an | grep 20000' or equivalent to confirm listening status and bound interfacesAffected if The DNP3 service is bound to accessible network interfaces and exposed to untrusted networks
You are affected if Triangle MicroWorks SCADA Data Gateway is installed with a version <= 3.00.0633 or matching one of the specific affected versions, and DNP3 protocol handling is enabled 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 dataUpgrade to Triangle MicroWorks SCADA Data Gateway version 3.00.0635 or later. Apply network segmentation and filtering to restrict unauthorized DNP3 traffic from untrusted networks.
