You probably want to check out these links as well.

It was called XSS before 2002. The wikipedia article that someone already
mentioned links to:

      http://www.cert.org/advisories/CA-2000-02.html
      http://webmonkey.wired.com/webmonkey/00/18/index3a.html
      http://httpd.apache.org/info/css-security/

All of which are from 2000.

I remember the vulnerability now known as "stored xss" being an issue as far
back as 1996-ish on web based forums, but I don't think it had any name at
that time.

I believe that Microsoft first came up with the cross-site 
scripting name.
They wrote a paper on the subject around 2002.

"Script injection" does sound like a more descriptive and 
accurate name.

The name "XSS" does not make sense in a lot of its applications. 

What "Stored XSS" and "Reflected XSS" have in common is the 
injection of
script into places where script wasn't supposed to be. Having 
more than one
site be involved is not the factor. What has been discussed 
in this thread
seems to me like it falls under "Stored XSS".

It would make more sense if this was called "script 
injection", but for some
reason the whole family was named XSS.

Who the heck names these things, anyway?

I wouldn't consider this an XSS attack. Where in the attack did 
information cross sites? This seems like it is an embedded 
XSS attack 
in that a malicious script was entered into a profile in hopes that 
victims would view and execute it. However, nothing was sent across 
sites via the script. The vulnerability was a lack of output 
validation in my opinion, which is the same vulnerability 
that an XSS 
attack would exploit. I don't know how you would classify the 
attack... Probably "self-replicating session riding". Yeah 
that has a 
nice FUD-factor to it.

Oh wow I'm wrong, I'm apparently thinking of current myspace bots 
which do as I described.  It looks this was in fact made 
possible by 
an XSS vulnerability.
Sorry

This isn't hacking at all. (at least not what I'd call

writing a script to go through myspace IDs (which

To prevent 
this, now myspace limits friend requests to a certain
number per day.
Hope that covers it!

This is the supposed confession of the hacker

I currently studying for CEH and just finished reading 
about XSS. So 
this is of special interest.
