JVN#55410403 Internet Explorer vulnerable in handling CDO protocol

When Internet Explorer (IE) accesses a website using CDO (Collaboration Data Objects), IE processes the contents as CDO data, ignoring their actual content types, and IE does not properly handle the Content-Disposition header field.
This could cause a download dialog box not to be displayed prior to downloading. The CDO protocol handler is included in an Office component, and Microsoft provides the fix for this component.

Impact

An arbitrary script could be executed without explicit user consent, as the download dialog box is not displayed on the user’s IE.
