CVE-2013-2821
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 · uneditedNovaTech Orion Substation Automation Platform OrionLX DNP Master 1.27.38 and DNP Slave 1.23.10 and earlier and Orion5/Orion5r DNP Master 1.27.38 and DNP Slave 1.23.10 and earlier allow remote attackers to cause a denial of service (driver crash and process restart) via a crafted DNP3 TCP 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 · moderate confidenceThe NovaTech Orion Substation Automation Platform (OrionLX and Orion5/Orion5r) contains a denial of service vulnerability in its DNP3 protocol implementation. Attackers can send crafted malicious DNP3 TCP packets to the device, causing the DNP driver to crash and triggering an automatic process restart. This affects both DNP Master (version 1.27.38 and earlier) and DNP Slave (version 1.23.10 and earlier) components.

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.
-
Confirm Orion device modelAccess the device web interface or system information to identify if the hardware is a NovaTech OrionLX, Orion5, or Orion5r unit. Check the product label, system info page, or management console for the model identifier.Affected if The device is not a NovaTech OrionLX, Orion5, or Orion5r platform.
-
Check DNP Master versionNavigate to the DNP Master configuration panel in the Orion management interface or check the firmware/driver version information. Look for the DNP Master component version number.Affected if The DNP Master version is 1.27.38 or earlier.
-
Check DNP Slave versionNavigate to the DNP Slave configuration panel in the Orion management interface or check the firmware/driver version information. Look for the DNP Slave component version number.Affected if The DNP Slave version is 1.23.10 or earlier.
-
Verify DNP3 protocol is enabledInspect the DNP3 configuration settings in the Orion platform. Check if the DNP Master or DNP Slave component is actively configured and listening for DNP3 TCP traffic.Affected if DNP3 protocol is enabled and the version conditions in steps 2 or 3 are met.
The environment is affected if it runs a NovaTech OrionLX, Orion5, or Orion5r device with DNP3 enabled and the DNP Master version is 1.27.38 or earlier, or the DNP Slave version is 1.23.10 or earlier.

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 firmware updates to newer versions of the OrionLX and Orion5/Orion5r devices. Implement network segmentation to restrict unauthorized DNP3 traffic and deploy IDS/IPS rules to detect anomalous DNP3 packets as a compensating control until patches can be applied.
