# Buffer Overflow Exploit

## Usage:

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

```bash

    $ cd /home/user # the username is important, for now only "user" is tested

    $ git clone [email protected]:Pablito2020/bufferoverflow-exploit.git practica

    $ cd practica

```

Then, install the binaries and disable some stack protections:

```bash

    $ 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):

```bash

    $ ./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.
