Internet Explorer vulnerable in handling CDO protocol
|
Internet Explorer is vulnerable in handling CDO (Collaboration Data Objects) protocol, which allows the download dialog box to be bypassed.
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.
NetAgent Co., Ltd. reported this vulnerability to IPA.
JPCERT/CC coordinated with the Microsoft Corporation under Information Security Early Warning Partnership.
