Using X-Forwarded-host in Web cache poisoning

Keith | Last updated: Dec 01, 2022 09:18PM UTC

I'm currently working on the web cache poisoning with an unkeyed header lab but whenever I put x=forwarded-host in my header I don't receive a response back. I even tested this by sending the header with just ?cb=1234 and the request went thru with a 200 ok response but as soon as I add the X-Forwarded-host into it, I receive nothing, nada. why is this happening

Hi Keith, Are you able to provide some details of the steps that you are taking to try and solve this lab so that we can take a look at this for you? It might be easier if you provide some screenshots so that we can see exactly what you are doing - feel free to send us an email at support@portswigger.net and include the screenshots there.
