CVE-2012-4334
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 ConnectDDNS method in the (1) STWConfigNVR 1.1.13.15 and (2) STWConfig 1.1.14.13 ActiveX controls in Samsung NET-i viewer 1.37.120316 allows remote attackers to execute arbitrary code via unspecified vectors. NOTE: some of these details are obtained from third party information.
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 confidenceThe ConnectDDNS method in Samsung NET-i viewer ActiveX controls (STWConfigNVR 1.1.13.15 and STWConfig 1.1.14.13) contains a vulnerability allowing remote attackers to execute arbitrary code via unspecified vectors. This is a critical client-side remote code execution vulnerability in video surveillance software.

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 Samsung NET-i viewer installationCheck the installed version of Samsung NET-i viewer on the system by reviewing installed programs or checking the application version information through the program's About or Help menuAffected if The installed version matches 1.37.120316 or falls within the affected ActiveX control versions (STWConfigNVR 1.1.13.15 or STWConfig 1.1.14.13)
-
Locate vulnerable ActiveX controlsSearch for the ActiveX control files STWConfigNVR.ocx and STWConfig.ocx on the system, typically found in the installation directory of Samsung NET-i viewerAffected if The files STWConfigNVR.ocx version 1.1.13.15 or STWConfig.ocx version 1.1.14.13 are present on the system
-
Verify ActiveX control registrationCheck Windows registry for registered ActiveX controls under HKLM\SOFTWARE\Microsoft\Code Store Database\Distribution Units or HKCU\Software\Microsoft\Windows\CurrentVersion\Ext\Stats for entries related to STWConfigNVR or STWConfigAffected if The vulnerable ActiveX controls are registered as browser extensions and available for instantiation in Internet Explorer
-
Confirm ConnectDDNS method availabilityInspect the ActiveX control's exposed methods using a tool such as OLEVIEW or by examining the control's type library to verify the ConnectDDNS method existsAffected if The ConnectDDNS method is present and accessible in the installed ActiveX control version
A system is affected if Samsung NET-i viewer version 1.37.120316 or either STWConfigNVR (v1.1.13.15) or STWConfig (v1.1.14.13) ActiveX controls are installed and the ConnectDDNS method is present and executable.

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 Samsung NET-i viewer to a patched version; if no update is available, disable or remove the affected ActiveX controls and implement network access controls to restrict exposure to untrusted networks.
