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 · unedited
The GENESIS32 IcoSetServer ActiveX control in ICONICS GENESIS32 9.21 and BizViz 9.21 configures the trusted zone on the basis of user input, which allows remote attackers to execute arbitrary code via a crafted web site, related to a "Workbench32/WebHMI component SetTrustedZone Policy vulnerability."

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 confidence

The GENESIS32 IcoSetServer ActiveX control in ICONICS GENESIS32 9.21 and BizViz 9.21 improperly configures the browser's trusted security zone based on user-supplied input. This allows a remote attacker hosting a malicious webpage to manipulate trusted zone policies, enabling arbitrary code execution in the context of the user's browser.

MitigationDisable the vulnerable IcoSetServer ActiveX control in Internet Explorer security settings, or upgrade to a patched version of GENESIS32/BizViz if available. Consider network segmentation to limit exposure to this industrial 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Genesis32 or BizViz version
    Open Windows Control Panel > Programs and Features, or check the registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries named 'GENESIS32' or 'BizViz'. Locate the DisplayVersion value.
    Affected if The DisplayVersion shows exactly 9.21 for either product
  2. Locate the IcoSetServer ActiveX control
    Search the Windows registry for the IcoSetServer control. Check HKCR\CLSID for a component named 'IcoSetServer' or search for files named IcoSetServer.dll in the GENESIS32 installation directory (typically C:\Program Files\ICONICS\GENESIS32 or similar).
    Affected if The IcoSetServer ActiveX control DLL is found on the system
  3. Verify ActiveX control is registered for Internet Explorer
    Check the registry key HKLM\SOFTWARE\Microsoft\Code Store Database\Distribution Units or HKCU\Software\Microsoft\Windows\CurrentVersion\Ext\Settings for the IcoSetServer CLSID. Also inspect HKLM\SOFTWARE\Classes\CLSID\{CLSID}\Implemented Categories to confirm ActiveX registration.
    Affected if The control has an active registry entry indicating it is registered as an Internet Explorer ActiveX control
  4. Confirm the control is enabled in Internet Explorer security settings
    Open Internet Explorer > Tools > Internet Options > Security > Trusted Sites > Custom Level. Scroll to 'ActiveX controls and plug-ins' and check if 'Initialize and script ActiveX controls not marked as safe' is set to Enable or Prompt.
    Affected if The setting is Enabled or the control appears in the list of 'Allowed ActiveX controls' in the zone where the user browses

A user is affected if Genesis32 or BizViz version 9.21 is installed AND the IcoSetServer ActiveX control is registered and enabled in any Internet Explorer security zone used for browsing.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Disable the vulnerable IcoSetServer ActiveX control in Internet Explorer security settings, or upgrade to a patched version of GENESIS32/BizViz if available. Consider network segmentation to limit exposure to this industrial software.

Recommended fix Moderate confidence
  1. Disable the IcoSetServer ActiveX control in Internet Explorer by adding the affected ICONICS DLL to the ActiveX kill bit list in Windows Registry
  2. Open Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility
  3. Create a new key with the CLSID for the IcoSetServer ActiveX control (consult ICONICS or US-CERT advisory for specific CLSID)
  4. Set the Compatibility Flags DWORD value to 0x00000400 to disable the control
  5. Alternatively, configure Internet Explorer security settings to disable ActiveX controls for untrusted zones
  6. Implement network segmentation to restrict access to systems running Genesis32/BizViz 9.21
  7. If possible, upgrade to a newer version of Genesis32/BizViz that addresses this vulnerability
Caveat Disabling ActiveX controls may impact functionality of Genesis32/BizViz web interfaces; test thoroughly before production deployment
