CVE-2013-2790
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 · uneditedThe master-station DNP3 driver before driver19.exe, and Beta2041.exe, in IOServer allows remote attackers to cause a denial of service (infinite loop) via crafted DNP3 packets to TCP port 20000.
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 confidenceA vulnerability in the IOServer DNP3 master-station driver allows remote attackers to cause a denial of service by sending specially crafted DNP3 packets to TCP port 20000, triggering an infinite loop in the affected driver versions prior to driver19.exe and Beta2041.exe.

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 IOServer installationCheck if IOServer software is installed on the system by looking for IOServer processes running or the IOServer application directory present.Affected if IOServer is installed on the system.
-
Verify DNP3 driver is enabledCheck if the system is listening on TCP port 20000, which indicates the DNP3 master-station driver is active. Use netstat -an | grep 20000 or similar network scanning tool.Affected if TCP port 20000 is open and listening, indicating the DNP3 driver is enabled.
-
Identify the DNP3 driver versionLocate the driver executable file (typically named driver.exe or similar in the IOServer installation directory) and check its file version properties, or use the IOServer administrative interface to view driver version information.Affected if The driver version cannot be determined to be driver19.exe or Beta2041.exe, or the version is identified as earlier than these releases.
-
Compare against vulnerable versionsReview the identified driver version against the known vulnerable range: all versions prior to driver19.exe and Beta2041.exe.Affected if The installed driver version is any version prior to driver19.exe or Beta2041.exe.
The environment is affected if IOServer with the DNP3 driver is installed and the driver version is prior to driver19.exe or Beta2041.exe, with TCP port 20000 open and listening.

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 dataUpdate the IOServer DNP3 driver to version driver19.exe, Beta2041.exe, or later. Implement network segmentation and firewall rules to restrict untrusted access to TCP port 20000 on IOServer devices.
