How I found DOM XSS via postMessage on bing.com and received a reward by Microsoft Bug Bounty namcoder.com/blog/how-i-fou… #microsoft #bugbounty #bugbountytips
like in which position u are trying to trigger it with postMessage('message', '*'), how do u debug it then exploit it? like how u check do if the code is vulnerable, it's a bit hard for me to understand, like i found one there wasn't dangerous source and any origin and didn't pop
Yes. Put the breakpoint inside the listener on the “Sources” tab. Then send the test postMessage({},’*’) on the “Console” tab. You should have some knowledge about the JavaScript to debug. When you send the postmessage, it will trigger the breakpoint
