# corCTF 2021 Rusty solution by c4e (author)
# this is the commented version of my rusty exploit
# I literally planned everything as I wrote it so hopefully the thought process I followed is
# understandable and you can have a laugh at some dumb stuff as well that I was too lazy to clean.

# The challenge got only 1 solve by M30W from team Dio. We talked about our solutions and they were
# pretty similar, except theirs made me realize how dumb I was thinking I needed a double poison null byte
# scenario to get a double overlap and work from there. That made my exploit way more painful than it

# corCTF 2021 Helpless solution by c4e (author)
# there are many different techniques that can be used to solve Helpless because of
# the nature of the challenge (UAF, variety of sizes allowed)
# My solution uses a House of Rust smallbin variation and then finishes the exploit off
# with a standard __GI__IO_file_jumps fsop triggered with stdout.

# feel free to dm me on discord if you want to discuss the solution. c4e#1255
