Outlook
SYSTEMS AFFECTED
Those using MS Outlook Express
PROBLEM
'1nternal' posted following. Outlook Express uses HTML to display
ceratin information in the 'outlook today' type part of outlook
express, ie, the number of unread messages in your inbox etc...
Because it is considered to be in the 'internet zone', this
information needs to be safely scriptable, thus it can be accessed
by any site in this zone. This allows for a possible (although
admittedly minor) privacy and possibly security problem. The
'problem' lies in the 'OutlookExpress.MessageList' ActiveX
control, which is marked safe for scripting, it allows for
counting the number of messages in any folder within outlook
express, as well as the number of unread items and a few other
things, s uch as setting options, however, the options are only
set for that instance only and are not saved. An example of
viewing the number of messages in a folder, as well as previewing
the message (creating the file 'C:\oe_prev$.eml' without the
users permission). It should be noted that this preview message
is not accessible remotely(without an exploit).
<script language="VBSCRIPT"><!--
set MsgList = CreateObject("OutlookExpress.MessageList")
MsgList.Folder = 6
msgbox(MsgList.Count)
location.href = MsgList.PreviewMessage
--></script>
Obviously, this could also be done in JavaScript, however it
would still require activeX support and OE5.
SOLUTION
Nothing yet, but I don't expect any as it is minor thing.
