What's ROP? Can you exploit the following to get the flag? . nc saturn.picoctf.net 56380
This challenge is identical to PicoCTF 2019's . We automate the solution (the linked writeup doesn't). explains the exploit in more detail.
The actual exploit ROP chain was obtained using by running ROPgadget --binary ./vuln --rop --badbytes "0a"
