Problem:RFC 7230(web, 50 points)"Get just basic information from this server (ctf.ekoparty.org)"Solution:RFC 7230 is an immediate hint as it refers to the HTTP protocol, so this challenge is definitely something to do with HTTP headers. There are quite a few HTTP methods though, such as the common "GET", "POST", and "HEAD". My immediate thought was the HEAD method, however this lead nowhere. There is however one that I hadn't considered for a while that was a bit obscure, which was the "OPTIONS" header. Sending an OPTIONS header request to the server via curl, we can see our flag in the response.curl -i -X OPTIONS http://ctf.ekoparty.org/HTTP/1.1 301 Moved PermanentlyServer: EKO{this_is_my_great_server}Date: Fri, 28 Oct 2016 03:44:02 GMTContent-Type: text/htmlContent-Length: 178Connection: keep-aliveLocation: https://ctf.ekoparty.org/Flag: EKO{this_is_my_great_server}
