I'm not sure how you can keep insisting that it's not a feature when it's
clearly been shown to be one. You either need to pay more attention, or get
a better dictionary.

What you're describing is possible directly through the anchor/link feature.
Even if it weren't, you could just as easily switch over to plain text and
insert the anchor tag manually. There is no exploit involved, as the ability
to use hyperlinks is an email isn't an *unintentional bug* but a very
popular *feature*.

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...

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 other
one, is actually VERY hard to explain..but yes... backspace... has a bug

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?

Thats why i the people who do understand it, can see that it

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".
