在free函数时有个明显的UAF漏洞 但是麻烦的是程序限制了创建的chunk的大小只能是0x100或0x150, 所以无法通过fastbin attack之类的方法来解题 但是可以利用unlink来构造fake chunk的地址为__malloc_hook的地址， 从而写入one_gadget来getshell 具体分析： 如果只存在一个UAF漏洞应该是无法利用unlink解题的（也许还有别的方法， 我太菜了想不出来， 这题还存在一个逻辑漏洞 如果输入chunk的data大小为0x100的话， 那么下一个chunk的prev_size 的低位字节会被置为零， 所以可以在上一个chunk伪造fake_chunk来触发unlink从而改变bss段中的chunk地址为__malloc_hook， 之后写入one_gadget来getshell EXP: # --- coding: UTF-8 --- from pwn import * import sys import os context ( arch = 'amd64' , os = 'linux' , terminal = [ 'tmux' , 'splitw' , '-h' ] ) #context(arch='i386', os='linux', terminal=['tmux', 'splitw', -h'])
