I'm trying to learn something about hacking and I've made it until realistic level 14 at hackthissite.com
I have tried many things until I was frustrated and searched for the first step on the internet. It is suggested to do a null-byte injection on this link: https://www.hackthissite.org/missions/realistic/14/news.cgi?story=.%00
However, this doesn't give me the expected result. Has there been a security fix in the Perl language that prevents this attack or can you explain me, what I am doing wrong?
