A simple HTTP web server written in x86 assembly (Intel syntax) during the pwn.college journey. It forks and handles both GET and POST HTTP requests, and does some simple file I/O.
GET searches the filesystem for the file specified in the URL path. If it finds it, it returns its contents in the response. If not, it returns nothing.
POST writes the data contained in the HTTP body to the filesystem in the location specified by the URL path. If the file exists, it will overwrite it.
It's low-level, messy, and definitely not secure.
Assemble it:
as ./server.s -o ./server.o
Link the object file:
ld ./server.o -o ./server
Set the CAP_NET_BIND_SERVICE capability to bind to TCP port 80:
sudo setcap 'cap_net_bind_service=+ep' ./server
Run the web server ./server and visit http://127.0.0.1/.
