CVE-2015-8039
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 · uneditedSamsung SmartViewer allows remote attackers to execute arbitrary code via unspecified vectors to the (1) DVRSetupSave method in the STWAxConfig control or (2) SendCustomPacket method in the STWAxConfigNVR control, which trigger an untrusted pointer dereference.
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 confidenceSamsung SmartViewer contains untrusted pointer dereference vulnerabilities in the STWAxConfig ActiveX control (DVRSetupSave method) and STWAxConfigNVR control (SendCustomPacket method). Attackers can exploit these to achieve remote code execution by tricking users into visiting malicious pages or receiving crafted network packets.

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 Samsung SmartViewer is installedSearch for Samsung SmartViewer in the system: look in Program Files for SmartViewer folders, check Add/Remove Programs, or search registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for SmartViewer entriesAffected if Samsung SmartViewer is found installed on the system
-
Verify presence of vulnerable STWAxConfig ActiveX controlSearch for STWAxConfig control files (typically STWAxConfig.ocx or similar DLL) in the SmartViewer installation directory, or check registry under HKLM\SOFTWARE\Classes\STWAxConfigAffected if The STWAxConfig control file exists or is registered on the system
-
Verify presence of vulnerable STWAxConfigNVR ActiveX controlSearch for STWAxConfigNVR control files in the SmartViewer installation directory, or check registry under HKLM\SOFTWARE\Classes\STWAxConfigNVRAffected if The STWAxConfigNVR control file exists or is registered on the system
-
Confirm ActiveX controls are browser-accessibleCheck if ActiveX controls are marked as safe for scripting in registry under HKLM\SOFTWARE\Classes\STWAxConfig\ScriptSafe or similar keys, and verify browser security settings allow ActiveX executionAffected if ActiveX controls are registered and not blocked by browser security settings
If Samsung SmartViewer and either the STWAxConfig or STWAxConfigNVR ActiveX controls are present and enabled, the system is vulnerable to this CVE since all versions are affected.

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 dataIf a patched version of Samsung SmartViewer is available, upgrade immediately. Otherwise, disable or remove the vulnerable STWAxConfig and STWAxConfigNVR ActiveX controls, restrict network access to systems running this software, and educate users about avoiding untrusted links.
