CVE-2014-5424
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 · uneditedRockwell Automation Connected Components Workbench (CCW) before 7.00.00 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an invalid property value to an ActiveX control that was built with an outdated compiler.
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 confidenceRockwell Automation Connected Components Workbench (CCW) versions before 7.00.00 contain a vulnerable ActiveX control that was built with an outdated compiler. The vulnerability allows remote attackers to send an invalid property value to this ActiveX control, potentially causing the application to crash (denial of service) or possibly achieving arbitrary code execution on the target system.

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.
-
Check if Connected Components Workbench is installedLook for CCW installation directory (typically in Program Files Rockwell Automation or similar) or check Windows Programs and Features for 'Rockwell Automation Connected Components Workbench'Affected if Connected Components Workbench is present on the system
-
Determine the installed CCW versionOpen the application and navigate to Help > About, or check the Windows registry under HKLM\SOFTWARE\Rockwell Automation\Connected Components Workbench for a Version value, or examine the uninstall entry in Windows RegistryAffected if The installed version cannot be determined or is <= 6.01.00
-
Compare version against affected rangeIf version is found, compare it numerically to 6.01.00 - note that any version 6.01.00 or lower is affectedAffected if The installed version is 6.01.00 or any earlier version (e.g., 6.00.00, 5.x, etc.)
-
Identify the vulnerable ActiveX controlExamine the CCW installation directory for ActiveX control files (.ocx) that were bundled with the outdated compiler, or check Internet Explorer Add-ons for Rockwell Automation ActiveX controlsAffected if The vulnerable ActiveX control from the outdated compiler build is present on the system
The environment is affected if Rockwell Automation Connected Components Workbench version 6.01.00 or earlier is installed, containing the ActiveX control built with the outdated compiler.

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 Connected Components Workbench to version 7.00.00 or later to obtain the patched ActiveX control built with a current compiler. If immediate patching is not possible, consider network segmentation and disabling ActiveX controls in Internet Explorer as compensating measures.
