Lab seems it doesn't work

Affan | Last updated: Apr 01, 2022 04:34AM UTC

Hi, This following lab doesn't work as expected. https://portswigger.net/web-security/web-cache-poisoning/exploiting-implementation-flaws/lab-web-cache-poisoning-unkeyed-query In this lab the response is expected to be cached. If we access the '/' page (homepage) of the lab it should return a cached response with a header 'X-Cache: hit' but it always returns the header 'X-Cache: miss'. I have also tried by adding and removing session cookies but it doesn't work.

Thanks for your message. Do you have any extensions enabled whilst you are working on this lab? For example, if you have Param Miner enabled, do you currently have this set to add a cache buster to your requests?

Hi Michelle, The lab is working now. Although i haven't tried anything different. Response is being cached properly. Maybe a new code is deployed.

I am facing the same problem in the following lab. https://portswigger.net/web-security/host-header/exploiting/lab-host-header-web-cache-poisoning-via-ambiguous-requests Response is not being cached. Can you please try to solve it.

Thanks for your message. We have checked the lab and confirmed it is possible to solve it using the solution provided. Do you have any extensions enabled?

I had param miner enabled, so I disabled that. Now it's working.

It seems the lab now sets the cookie to httponly, so I can't complete the lab since alert(document.cookie) does not work

Thanks for your message. We haven't made any changes to the functionality of the labs, we were just making changes to the infrastructure, so the labs will behave in the same way as before. Can you tell us more about the steps you were taking, please? Were you following through with lab solution?
