CVE-2014-4647
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 the loadExtensionFactory method in the TSVisualization ActiveX control in Embarcadero ER/Studio Data Architect allows remote attackers to execute arbitrary code via unspecified vectors.
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 confidenceStack-based buffer overflow in the loadExtensionFactory method of the TSVisualization ActiveX control in Embarcadero ER/Studio Data Architect. The vulnerability allows remote attackers to execute arbitrary code by overflowing a buffer on the stack through unspecified vectors.

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 ER/Studio Data Architect installationSearch for the application in standard installation paths (C:\Program Files\Embarcadero\ERStudio Data Architect or C:\Program Files (x86)\Embarcadero\ERStudio Data Architect) or check Add/Remove Programs for Embarcadero ER/Studio Data ArchitectAffected if The application is installed on the system
-
Locate the TSVisualization ActiveX control DLLSearch for files named TSVisualization.dll, TSVisAx.dll, or similar TSVisualization* files within the ER/Studio installation directory and subdirectoriesAffected if The TSVisualization DLL exists in the application folder
-
Verify ActiveX control registrationCheck Windows Registry under HKLM\SOFTWARE\Classes\TypeLib or HKCR\TypeLib for entries containing TSVisualization, or run 'regsvr32 /s <path_to_dll>' to attempt registration and observe resultAffected if The TSVisualization ActiveX control is registered in the Windows registry
-
Check browser ActiveX settingsInspect Internet Explorer settings under Tools > Internet Options > Security > Custom Level > ActiveX controls and plugins, or check registry keys in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains for sites that may be allowed to run this controlAffected if ActiveX controls are enabled or the TSVisualization control has been allowed to run for any zone
If Embarcadero ER/Studio Data Architect is installed AND the TSVisualization ActiveX control DLL is present on the system, the environment is affected by this vulnerability regardless of version.

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 patch when available; if no patch exists, disable the TSVisualization ActiveX control or implement network-level restrictions to block exploitation attempts.
