题目给了一堆启动鸿蒙liteos的套件,用jefferson解压rootfs.img得到文件系统,在bin目录里即可找到crakeme文件。直接拖进ida分析
图片描述
首先清理了一个全局变量bss_struct,然后进入了judge函数
图片描述
judge函数首先读取了/etc/config文件并将其读取到了内存里,所以我们首先来写脚本解析一下/etc/config文件:四个字节为一组,将每一组的值打印出来

from pwn import *

file1=open("./rootfs/etc/config","rb+").read()

length=len(file1)

nums=[]

for i in range(length//4):

    num=u32(file1[0+(i*4):4+(i*4)])

    success(hex(num))

图片描述
先不用管每个数值的具体用处,继续用ida进行静态分析
图片描述
这个地方取出config中的第一个数值用作偏移从栈中取值,变量newS到bp的距离是0x74,而这里取得值为&newS+4*0x1e即&newS+0x78,正好是返回地址的位置,所以这里取得值为返回地址。
图片描述
Constructor函数会初始化一个结构体S,并将其指针放入全局变量bss_struct中,S结构体结构如下
图片描述
为了方便,给全局变量bss_struct也定义了一个结构体,结构如下
图片描述
其中offset是从config中取值时用的下标,s_ptr是储存S结构体用的数组。初始化S结构体时会经历以下步骤:

初始化完成结构体之后进入Parser函数,该函数首先会打印S.content的内容,再就会调用call_vfunc函数
图片描述
call_vfunc函数会先根据传入的参数从bss_struct.s_ptr取出相应的S结构体,如果S.target_ptr!=0就将target_ptr作为第一个参数(r0)来调用S的函数指针
图片描述

下面又取出了config[1]并储存了起来,取出了config[2]作为了循环次数,之后进入了大循环,在循环里构造了一个新的S结构体,并且它的函数指针是通过"返回地址+config中的偏移"得到的(config的下标从3开始),经过两个永真的if之后,将新的S结构体的内容整体复制给了位于bss_struct.s_ptr[0]的结构体
图片描述

第一次逆到这里的时候完全看不懂在干什么。。只能动态调试看看发生甚么事了,在调试中就可以发现,bss_struct.s_ptr[0]->target_ptr的值和bss_struct.s_ptr[2]的值是一样的,并且bss_struct.s_ptr[0]和bss_struct.s_ptr[1]储存的指针也是一样的。要搞清楚发生了什么,得回到上面构造结构体的时候看一下
图片描述
首先构造了1、2号结构体,然后有销毁了1、2号结构体,我们查看Destructor函数就可以发现它free结构体指针之后没有清空。。。造成了一个uaf
图片描述
所以情况是这样的

free(S1)

free(S2)

malloc S0

malloc S0.taret_ptr

所以S0.target_ptr和S2指向的是同一个chunk,循环里实际上是在对S2结构体也就是bss_struct.s_ptr[2]中的结构体进行操作。
循环后半段就是取出bss_struct.s_ptr[2]结构体,将bss_struct.s_ptr[2]->target_ptr赋值为 bss_struct.s_ptr[6]->target_ptr(输入的位置),然后调用bss_struct.s_ptr[2]的函数指针,并判断返回值是不是1。
所以整体的逻辑就非常清晰了:每个循环依次调用ret_addr+confg[3+i]处的函数,以输入为参数,并判断返回值,循环九次
config中的后九个值解析成int是显然是负数,返回地址可以直接在ida里面找,为0x58DC(main函数中call judge的下一条指令的地址),由此可以还原出九个函数地址:

    if(i>2):

        nums.append(num)

for i in nums:

    tmp=(i^0xffffffff)+1

    success(hex(0x58DC-tmp))
