CVE-2013-0681
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 · uneditedCogent Real-Time Systems Cogent DataHub before 7.3.0, OPC DataHub before 6.4.22, Cascade DataHub before 6.4.22 on Windows, and DataHub QuickTrend before 7.3.0 allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via malformed data in a formatted text command.
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 confidenceMultiple Cogent DataHub products contain a denial-of-service vulnerability where malformed data in formatted text commands triggers a NULL pointer dereference, causing the application to crash. The vulnerability is remotely exploitable without authentication.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 installed Cogent DataHub productCheck the installed software for one of: Cogent DataHub, OPC DataHub, Cascade DataHub, or DataHub Quicktrend. Look in Add/Remove Programs (Windows) or check the application name in the program directory.Affected if Any Cogent DataHub variant (Cogent DataHub, OPC DataHub, Cascade DataHub, or DataHub Quicktrend) is installed
-
Determine the installed versionOpen the Cogent DataHub application and check Help > About, or locate the version in the Windows Add/Remove Programs entry, or check the version in the program's executable properties.Affected if Version cannot be determined or is not visible in standard locations
-
Compare version to affected rangesMatch your installed version against these affected ranges: Cogent DataHub <= 7.2.2 (including 7.0, 7.0.2, 7.1.0, 7.1.1, 7.1.1.63, 7.1.2); OPC DataHub <= 6.4.21 (including 6.4.20); Cascade DataHub <= 6.4.21 (including 6.4.20); DataHub Quicktrend <= 7.2.2Affected if Installed version falls within any of these affected ranges or matches any specific versions listed
-
Verify service is running and network accessibleCheck if the Cogent DataHub service is running (look for the process in Task Manager or as a Windows service) and confirm it is listening on its configured network port (default TCP ports 4500 or 80 for web interface).Affected if The service is running and accessible over the network (required for remote exploitation)
If a Cogent DataHub variant is installed with a version in the affected ranges AND the service is running and network-accessible, the environment is vulnerable to CVE-2013-0681.

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 affected products to Cogent DataHub 7.3.0 or later, OPC DataHub 6.4.22 or later, Cascade DataHub 6.4.22 or later, or DataHub Quicktrend 7.3.0 or later.
