Thanks for your information pratul

I do know about DOM and XSS, I wasn't able to reproduce this bug on my end
that's why i requested you to post video on that.

I do agree with vipul that this is not working, and I checked this bug twice
already so i am quite sure about it that this flaw isn't working on
yahoomail. If in case this works then please come up with a POC video :)

Looking forward for your response :)

Cheers,
Rockey

Hello Pratul!

I'm sure that the flaw was working on 13th June when you disclosed it on
the list.
But its not working today and input is being filtered. Please check it out.

Thanks Brother,

                      See, how this occurred, Basically in most of the
cases Developers  Simply design a APIs and when the client request for any
page this APIs gets Stored in the Client side. its main task is to takes the
user input and shows the result immediately  to the client without sending
request to the server. so when this type of APIs is vulnerable to XSS this
is called the DOM based XSS.

Now in this case, when we click on [New Folder] for creating any new
folder and provide any javascript, it directly took by the API stored in the
client side when the inbox page is load in the client side in yahoomail, and
get reflected.

that's all the story Bro, hope you understand what i really want to say.

Thanks,
Pratul Agrawal

Its working Bro.  I think u had done some mistakes so u try it again with
check that javascript execution feature is enable in your browser. and bro
for execution of script it is must to use proper syntax that contain special
characters. just put "><script>alert(123)<script>  in the New Folderfield comes in the
Move button and you will saw a pop up message with 123 reflected.

Have a nice time bro,
Pratul Agrawal
