CVE-2013-2829
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 · uneditedMatrikonOPC SCADA DNP3 OPC Server 1.2.2.0 and earlier allows remote attackers to cause a denial of service (infinite loop) via a malformed 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 confidenceThe MatrikonOPC SCADA DNP3 OPC Server versions 1.2.2.0 and earlier contains a vulnerability where processing a malformed DNP3 protocol packet triggers an infinite loop, causing the service to become unresponsive. This is exploitable remotely without authentication.

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.
-
Locate the MatrikonOPC DNP3 serviceOpen Windows Services console (services.msc) and look for a service named 'MatrikonOPC SCADA DNP3 OPC Server' or check Program Files for MatrikonOPC installation directories.Affected if The service or installation directory exists on the system.
-
Determine the installed versionRight-click the DNP3Server.exe executable in the installation directory, select Properties, then view the Details tab for the Product Version. Alternatively, check the version info in the Windows registry under HKLM\SOFTWARE\MatrikonOPC\DNP3 or the application's About dialog.Affected if The version displayed is 1.2.2.0 or lower, or displays as version 1.2.0.
-
Verify the DNP3 protocol is enabledOpen the MatrikonOPC DNP3 configuration tool or check the server's configuration file (typically named DNP3Config.xml or similar in the installation directory) to confirm DNP3 communication is actively enabled.Affected if DNP3 protocol support is enabled in the configuration.
-
Confirm network listening statusOpen Command Prompt and run 'netstat -an | findstr LISTENING' or use TCPView to check if the DNP3 server process is bound to network ports (commonly TCP port 20000 for DNP3).Affected if The service is listening on a TCP port accessible over the network.
The system is affected if MatrikonOPC SCADA DNP3 OPC Server is installed with version 1.2.2.0 or lower and the DNP3 protocol is enabled with the service exposed 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 vendor-supplied patch for CVE-2013-2829; as an interim measure, network-segment the affected server and restrict DNP3 traffic to trusted sources only.
