Description Josh Bressers 2006-04-13 02:26:58 UTC 
JavaScript execution in mail when forwarding in-line


Georgi Guninski reports that forwarding mail in-line while using the default
HTML "rich mail" editor will execute JavaScript embedded in the e-mail
message. Forwarding mail in-line is not the default setting but it is easily
accessed through the "Forward As" menu item.

This JavaScript runs with the full privileges of the client and could be
used to install malware or send spam.

In Thunderbird 1.0.7 and below and Mozilla Suite 1.7.12 and below JavaScript
is also executed when you reply to a mail, though limited to the sandbox of
the  message.  This  script  could spy on or alter the message you are
composing.

Workaround

Switch to "plain text" mail composition, this vulnerability only affects
HTML mail composition (the default). On the "Composition and Addressing" tab
of Thunderbird's Account Settings dialog uncheck the "Compose messages in
HTML format" option to compose messages in plain text.
