CVE-2014-9204
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 · uneditedStack-based buffer overflow in OPCTest.exe in Rockwell Automation RSLinx Classic before 3.73.00 allows remote attackers to execute arbitrary code via a crafted CSV file.
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 stack-based buffer overflow vulnerability exists in OPCTest.exe, a component of Rockwell Automation RSLinx Classic. The vulnerability is triggered when the application processes a specially crafted CSV file, allowing remote attackers to overflow a stack buffer and execute arbitrary code. The flaw exists in versions prior to 3.73.00.

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 RSLinx Classic installationLocate RSLinx Classic on the system. Check Program Files folders or the Windows registry under HKEY_LOCAL_MACHINE\SOFTWARE\Rockwell Software\RSLinx for installation evidence.Affected if RSLinx Classic is not installed on the system, the vulnerability does not apply.
-
Identify installed RSLinx Classic versionOpen RSLinx Classic and navigate to Help > About, or check the Windows registry key for the Version value under the RSLinx installation entry.Affected if The installed version is any version prior to 3.73.00 (for example, 3.70.00, 3.72.01, etc.).
-
Verify OPCTest.exe component existsSearch the RSLinx installation directory for the file OPCTest.exe. This executable is bundled with RSLinx Classic and contains the vulnerable code.Affected if OPCTest.exe exists in the RSLinx installation folder, indicating the vulnerable component is present.
-
Confirm CSV import functionality is accessibleLaunch OPCTest.exe or the RSLinx Classic application and verify whether it can import or process CSV files. Check menus for import or file loading options that handle CSV data.Affected if The application allows CSV file import or processing, which is the attack vector for this buffer overflow.
The system is affected if RSLinx Classic is installed with a version lower than 3.73.00 and the OPCTest.exe component with CSV processing capability is present.

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 data3.73.00
Update RSLinx Classic to version 3.73.00 or later to patch the vulnerability. Additionally, restrict network access to systems running RSLinx and exercise caution when opening CSV files from untrusted sources.
