Vulnerability discussion

This policy setting allows you to manage whether ActiveX controls and plug-ins can be run on pages from the specified zone. ActiveX controls not marked as safe should not be executed. If you enable this policy setting, controls and plug-ins can run without user intervention. If you disable this policy setting, controls and plug-ins are prevented from running.

Check content

The policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> "Run ActiveX controls and plugins" must be "Enabled", and "Disable" selected from the drop-down box. Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4 Criteria: If the value 1200 is REG_DWORD = 3, this is not a finding.

Fix text

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> "Run ActiveX controls and plugins" to "Enabled", and select "Disable" from the drop-down box.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
