The Initialize and script ActiveX controls not marked as safe property is not set properly for the Internet Zone. (Cat II impact)

ActiveX controls that are not marked safe scripting should not be executed. Although this is not a complete security measure for a control to be marked safe for scripting, if a control is not marked safe, it should not be initialized and executed.
