When an attachment of MIME Type text/html is added to a bug, it is displayed
when attachment.cgi is called with edit or fiew options.  When that page
contains a redirect to a site outside of the bugzilla server, that page is
displayed instead.

This seems like it could be a security problem, but people with more knowledge
than me should determine that.  It seems like more of a problem when the page
redirected to is a cgi.  

An example of the type of file that is attached:

<html>
<head>
<meta http-equiv="refresh" content="0;URL=http://somesite.com/">
</head>
<body>
</body>
</html>

I'll try to add an attachment like this as well.

If this isn't a problem, please let me know, and I guess if it is a problem, let
me know sooner.
Thanks

Reproducible: Always
Steps to Reproduce:
1. add attachment as described above
2. edit attachment


Actual Results:  
was redirected to external page

Expected Results:  
The page was displayed.

Appears in both Mozilla and IE.  Found this problem in Bugzilla 2.17.6.  Seems
to still appear in 2.18rc2, but I have not had a chance to install that to
verify it.
Attaching an example file forward.html
next time, checkmark the security box for stuff like this... it mails a bunch of
extra people to get them hopping on it. :)

(not that this issue is exactly hopping, because it's a pain in the butt to fix
- see the bug I'm duping it to)

Hmm, I take that back, reading this a little closer, this isn't actually the
same issue (but sort of related anyway).

I really don't know if there's much we can do about this...  Jesse's probably
the guy to tell us what to do here.

I don't think redirecting attachments are a problem.
What's the status of this bug? Still a security bug? Still open?

Maybe the reporter wondered if it was possible for the called website to access
bugzilla cookies or to launch some script/SQL request on behalf of some bugzilla
user.
I don't think this is either a bug or a security bug - I agree with Jesse.
Suggest WONTFIX.

Marking the bug as WONTFIX per comments 5 and 7; but letting the security flag
for now. If you disagree, reopen the bug, else remove the security flag.
