I'm not sure why you insist on continuing this, but you're not really
helping your case.

The bottom line is that it's an intentional feature. That is why it A)
consistently works and B) works across most mail clients.

feature...rightttttt... thats why i see emails, covered in
links,....daily...and, it is ommal...
your a fool.

and show the email instead of hiding the thing..

So much for that Ryan guy "editing" secn3t's emails. He *just* sent me
this because he's completely upset over his "major exploit" turning out to
be a "simple feature" :(

Only took you , what 15 flame emails.... and, i have UNsubbed from list,

screw yourself.
you wanted Fd , now you have 1 less Fd :)
bye!
and, your domain, papsy.net... is going down for maintenance i
believe....someone just told me.. idk..
you should not abuse ppl, before looking into the actual email, why would
there be x41's in it.. i am guessing you have not studied the other side,
wich is hyperlink with OUT html...
there is many ways to code inject.,... its called, make a nice colorful
email...with a bad link.
now fuckoff retard.

there is ANOTHER method idiot....

ut, you wont figue it :)

and how ?
what if made a damn email with ALL text as a bad-link...and, say you
open it, and, just happen to accidnetally hover and, click.. wich, many ppl
do... it is not some spam email with a link, and NO it is NOT a feature..
idiot again.

#1 - No one has replied since I reproduced your "proof of concept."

#2 - Even if they had, you're replying directly to me - not the list.

#3 - None of that is necessary. Type in text, highlight it and then
click the anchor/link icon. From there, you can insert the target URL (and
use the text of your choice). This is possible across most (all?) mail
clients, as well as forums. It's an intentional feature that let's you
specify anchor text.

Assuming you're using a mail client that doesn't allow that (which I'd
find very hard to believe that it has an anchor/link icon and doesn't have
that feature) but even if that were the case: who is really vulnerable here
(and to what? specifying anchor text != code injection).

This is what i tried to explain...

enter text, darken it, and then link , i said this 3 times..yet one
person managed to finally do it, after having tospell it.
no , i am, not a smartarse. and the other method, i should just have
left out.
now, nomore fd for me,.
thanks,.

The reason why no one understood your ground-breaking vulnerability
(broken English aside) is because it's a *feature*. Whether you're
being a smartass right now or not is irrelevant, being that my email
generated the exact same thing as yours did (view source on both of them).
The difference is, you're doing some backspace *trick* whereas I'm
entering text, highlighting it and then clicking the link icon.

Congratulations on wasting everyone's time, they were right to have
abandoned this thread from the start.

Here again....

I will write a sentence now, and, i will just copy, so it is
'darkened' text , then with NO backspace just leave the text darkened, and
goto 'link' , and enter a link.. the text will turn to red.

I should have said just 'copy, then hit link... because the

I am really shocked at the brubbish talk i have copped from
this.

Do the research... then call yourself a 'team'...please :s

The PoC, is easy as hell to reproduce. I am shocked a team,
cannot do it..

even the easy one wich is just copy/backspace, and, hit link
and enter a link!
simple ?

At the end of the day, you're going to be treated like a
child as long as you continue to type like one.

The entertaining part for me is how each of your replies
contradicts a previous one. According to you, this *
vulnerability* *has existed for years*. And also according
to you, the reason why the original email was filled with spelling errors is
because it *was rushed out due to you being "awake" at
6AM.* Do you see the inconsistency between those two
statements? Your response to Christian also indicated that you
* **didn't just discover this*.

IF this is an old vulnerability and IF you've known about
it for an extended period of time - WHY did you have to post it right when
you did? It's old, you've known about it for a while, it's existed for
years, yet it couldn't wait until later in the day? It couldn't wait until
you had time to skim over the email and correct any spelling/grammar
mistakes? It absolutely had to be posted right then and there?

Furthermore, pretending that we [the readers] are somehow
at fault here (for not understanding) isn't going to get you very far. The
only thing consistent in this entire thread is that people
*kind of* want to know what you're talking about, but
aren't able to due to the poor writing style and spelling/grammar errors.

It should be noted that no one is being anal about typos,
I fully understand that people make mistakes. The difference is that it
appears you didn't even so much as proof read the original email.

Hi n3td3v... oops!... secn3t (that is close),

Sorry but I don't understand anything to this thread.
Each of your emails is such a pain to read, that I stop
at the first
sentence.
We are all busy and don't want to take 20 min to
decipher your writing
with the risk that it is not deserving it.
Please clarify and give consistent technical facts.

Thanks.

This is NOT coded..  the PoC i am explaining, is

possible with simply

copyying text,then using a sequence of keys, to make

the actual

sentence/s, appear.
This code is not what shows up when it is dissected.
It shows up with many x41 all over the email when it

is done properly .

Regards.

    How this helps in sending spam is beyond me.

        Microsoft had problems with a backspace in the

past. Search for

        "CSRSS
        Backspace Bug".
