There is no exploitation step: after accepting a connection, the service opens flag.txt and prints it. Connect and read until EOF.

Reference solver

The reference solver supplied with the writeup:

#!/usr/bin/env python3
from pwn import *

context.log_level = "error"

p = process("./main") if args.LOCAL else remote("127.0.0.1", 9016)
print(p.recvall().decode())
p.close()
