Pablito2020 / bufferoverflow-exploit

Buffer Overflow Exploit

Usage:

First, clone the project (THE DIRECTORY IS IMPORTANT FOR CALCULATING THE RETURN VALUE, SO PLEASE, FOLLOW THIS INSTRUCTIONS):

    $ cd /home/user # the username is important, for now only "user" is tested
    $ git clone [e-mail]:Pablito2020/bufferoverflow-exploit.git practica
    $ cd practica

Then, install the binaries and disable some stack protections:

    $ sudo make install

Finally, run the exploit (if 70 isn't enough, try different numbers or create a loop that tries from 20 to 200):

    $ ./exploit 70

Additional information

If you want to see how you can overflow the version that uses puts instead of printf (which was disabled with the -fno-builtin-printf flag), you can check out the "gdb-only" branch.
