Solution:

保护如下：

1
2
3
4
5
Arch:     i386-32-little
RELRO:    Partial RELRO
Stack:    No canary found
NX:       NX enabled
PIE:      No PIE (0x8048000)

主函数如下：

int sub_80486B7()
{
  unsigned int v0; // eax
  char buf; // [esp+Ch] [ebp-3Ch]
  int v3; // [esp+3Ch] [ebp-Ch]

  v0 = time(0);
  srand(v0);
  memset(&buf, 0, 0x30u);
  read(0, &buf, 0x30u);
  puts("Give you a cursor: ");
  __isoc99_scanf("%ud", &v3);
  return sub_8048738(&buf, v3);
}

sub_8048738 函数如下：

1

int __cdecl target(char *s, int a2)
{
  size_t v2; // eax
  char v4[16]; // [esp+8h] [ebp-20h]
  int v5; // [esp+18h] [ebp-10h]
  int v6; // [esp+1Ch] [ebp-Ch]

  v5 = abs(a2);
  if ( v5 < 0 )
  {
    v6 %= 0x20;
  }
  else
  {
    v6 = rand() % 16;
    s[16 - v6] = 0;
  }
  v2 = strlen(s);
  memcpy(&v4[v6], s, v2);
  return puts("copy over!");
}

可以看到考的是 abs 的漏洞，即 abs 在输入 -‭2147483648 时无法返回正整数

依靠这个我们可以完成漏洞利用

__int64 __fastcall main(__int64 a1, char **a2, char **a3)
{
  char buf; // [rsp+0h] [rbp-10h]

  setbuf(stdin, 0LL);
  setbuf(stdout, 0LL);
  setbuf(stderr, 0LL);
  puts("Give you a gift...");
  read(0, &buf, 8uLL);
  __printf_chk(1LL, &buf);
  sub_400846();
  return 0LL;
}

这里可以用%p%p%p%p来绕过__printf_chk的检查，从而得到 libc 信息

sub_400846 函数如下：

__int64 sub_400846()
{
  size_t v0; // rax
  char v2; // [rsp+0h] [rbp-50h]
  char s[8]; // [rsp+30h] [rbp-20h]
  __int64 v4; // [rsp+38h] [rbp-18h]
  int v5; // [rsp+4Ch] [rbp-4h]

  *s = 0LL;
  v4 = 0LL;
  write(1, "Tell me U filename\n", 0x13uLL);
  sub_4008F8(s, 0x10);
  v0 = strlen(s);
  v5 = 3 * v0 - 48 * ((0xAAAAAAAAAAAAAAABLL * (3 * v0) >> 64) >> 5);
  write(1, "And the content:\n", 0x11uLL);
  return sub_4008F8(&v2, v5);
}

这里v5 = 3 * v0 - 48 * ((0xAAAAAAAAAAAAAAABLL * (3 * v0) >> 64) >> 5);限定了之后字符串能写的个数

主要看函数 sub_4008F8：

signed __int64 __fastcall sub_4008F8(unsigned __int8 *a1, int a2)
{
  signed __int64 result; // rax
  unsigned __int8 *buf; // [rsp+18h] [rbp-8h]

  buf = a1;
  do
  {
    if ( read(0, buf, 1uLL) <= 0 )
      exit(1);
    result = *buf;
    if ( result == 10 )
      break;
    ++buf;
    result = &a1[a2];
  }
  while ( result != buf );
  return result;
}

可以看到result = &a1[a2];一句，也就是说如果 buf 增长到&a1[a2]就会停止输入，最大的字符状态是当你之前输入 15 个字符的时候

但是试了下没成功，可写区域还是不够大，最后尝试 16 个字符，这样就相当于result = &a1[0]，发现绕过了

查看原来是&a1[0]的地址小于 buf，所以不管 buf 如何增长都不会等于&a1[0]，后面就提权拿 flag 即可

这题一开始我没看见有一个 off-by-null 漏洞，就导致我这题，用的是个非预期解

这题能改_IO_2_1_stdout_和_IO_2_1_stderr_里的所有结构体内容，所以就利用伪造 vtable 来做即可

在调用 puts 时，会跳转到伪造的 vtable 内伪造的地址，并将_IO_2_1_stdout_的地址也就是它的魔数地址传入到 rdi 里，所以修改一下魔数即可提权

加个;sh即可

每当该函数调用 fprintf 函数时，程序总会返回 0x7ffc116f26c8 地址上所对应的地址

由于程序 Full RELRO，所以程序地址修改地方有限，这里不能使用自己在 bss 段上面写的 shellcode

将其改成 addr_one_gadget 地址即可，不过 execve 的 argv 参数那要随缘，看地址上面的值嘛时候自己乐意变成 0 你就提权了

  return fgets(byte_6030C8, 45, stream);
}

这里可以看到程序读取了 flag，那么这道题就可能不需要提权即可获得 flag

然后又因为 SCP_Project_remote 的初始值被赋值为了 0x60，这说明这块可能能够帮助我们进行 fastbin 的伪造

又因为 byte_6030C8 和 SCP_Project_remote 的地址离得很近，所以可能是依靠伪造一个 fastbin 来进行信息泄露

可以看到存在 UAF 漏洞

一次制造三个堆块，一开始我被题目信息误导了，以为这块能进行整数溢出实现越界写，结果调试发现最后用的大小只会是 32 位的大小，就是说没有整数溢出

这块就想了很久，如何才能顺利制造一个 double free，因为除了要伪造 0x50 大小的堆块外还有多余的堆块，最后找到了在实现正常流程的 double free 前多插一个 free 来进行绕过的方法

伪造到 SCP_Project_remote 后读取内容即可得到 flag

Solution:

程序的意思就是输入英文，然后都减去 96，转换成数字，填到数独列表里值为 0 的地方

然后检测数独是否正确，正确就通过，数独表能在unk_405020很容易地提取出来：

int sub_401410()
{
  char v1[19]; // [esp+16h] [ebp-2Ah]
  char v2[19]; // [esp+29h] [ebp-17h]
  int v3; // [esp+3Ch] [ebp-4h]

  sub_401D70();
  printf("%s", "Please enter your flag:");
  scanf("%s", v2);
  v3 = -1;
  do
  {
    ++v3;
    v1[v3] = v2[v3];
  }
  while ( v2[v3] );
  sub_4014DC(v2);
  sub_40156A(v2, &unk_405020);
  sub_4017D1(&unk_405020);
  puts("Congratulations, you successfully solved this little problem!");
  printf("flag为：flag{%s", v1);
  putchar(125);
  return 0;
}

根据程序内所写，是每四位一提取，之前一共有 300 多个数字，提取后可以清晰看到 9 × 9 的表，也就是 81 个数字

6, 7, 9, 2, 5, 8, 1, 4, 3,
3, 1, 2, 5, 8, 4, 7, 0, 0,
0, 8, 0, 7, 9, 0, 5, 3, 2,

7, 2, 4, 0, 1, 3, 0, 5, 8,
8, 6, 5, 4, 7, 9, 3, 0, 1,
9, 3, 1, 8, 2, 5, 4, 0, 0

然后扔到数独求解的工具上求解，把每一位求解出来的数字加上 96 转成 ASCII 码即是答案

for i in range(0, len(table3)):
    res += chr(table3[i] + 96)

先把算法流程用如下脚本逆过来

1

3
4
5
6
7
with open(r'out.txt', 'r') as rl:
    rl = rl.readlines()

rl.reverse()

with open(r'test.txt', 'w') as wl:
    wl.write(''.join(rl))

然后把加都改成减，再用下面的脚本跑即可

  sub_401020(&unk_404118, "Welcome to ACTF_Splendid_MineCraft!");

  if ( strlen(&Str1) == 26 )

    }
  }
  else
  {
    sub_401020("Wrong\n");
  }
  return 0;
}

能看出这里用了 self-Modifying Code 所以我们在JUMPOUT(__CS__, &byte_405018[256]);处下断点，查看程序

这是一开始反汇编出来的程序，后面的反汇编存在断层，所以我们可以根据这个函数自己写脚本复原

void sub_12451D8()
{
  signed int i; // edi

  for ( i = 0; i <= 337; ++i )
    *((_BYTE *)&loc_12451FC + i) ^= 0x72u;
  JUMPOUT(unk_124525E);
}

脚本如下，每次 IDA 加载的基址都不一样，脚本按自己的地址来写：

1

#include <idc.idc>

static main(){
    auto addr = 0x405018 + 0x1e4;
    auto i;
    for(i = 0; i <= 337; ++i){
        PatchByte(addr + i, Byte(addr + i) ^ 0x72);
    }
}

解密完函数如下：

  signed int j; // [esp-4h] [ebp-8h]
  int v21; // [esp+0h] [ebp-4h]

  v21 = 4215261;
  for ( i = 0; i <= 337; ++i )
    *(&loc_4051FC + i) ^= 0x72u;
  v21 = a1;
  v19 = 0;
  v12 = 51;
  v13 = 64;
  v14 = 49;
  v15 = 98;
  v16 = 59;
  v17 = 98;
  v4 = 101;
  v5 = 108;
  v6 = 99;
  v7 = 111;
  v8 = 109;
  v9 = 101;
  v10 = 32;
  v18 = 8;
  JUMPOUT(8, 10, &loc_4052D0);
  v11 = 0;
  for ( j = 0; j < 6; ++j )
  {
    *(&v21 + j - 32) = (*(&v21 + j - 43) ^ *(&v21 + j - 24)) + 35;
    if ( *(&v21 + j - 32) == *(j + a2) )
      ++v19;
  }
  return v19 == 6;
}

在if ( *(&v21 + j - 32) == *(j + a2) )下个断点，对于 0x405018 的相对偏移是 0x30a，edx 的值为 flag 的字符

于是每位每位看即可得到前 6 位字符，为 yOu0y*

之后通过调试得到一开始函数内第二次加密所需的 v5 变量的数值为 0x20，接着使用如下脚本：

1

9
#include <idc.idc>

static main(){
    auto addr = 0x405018;
    auto i;
    for(i = 0x100; i <= 0x1f0; ++i){
        PatchByte(addr + i, Byte(addr + i) ^ 0x20);
    }
}

解码后对应 c 代码如下：

  signed int v6; // edi

  for ( i = 0; i < 6; ++i )
  {

    v4 = *(a1 + i + 18);
    *(a1 + i + 24) = a2;
  }
  for ( j = 0; j < 6; ++j )
  {

    *(a3 + j) = a2;
  }
  v6 = 0;
  while ( 1 )
  {
    if ( v6 >= 6 )
      return ((a2 + 18))();
    v7 = a1 - 256;
    a2 = v6 + 131;
    LOBYTE(a2) = *(v7 + v6 + 358);
    if ( *(v7 + ((v6 + 131) ^ *(a3 + v6))) != a2 )
      break;

  char v5; // [rsp+20h] [rbp-88h]

  v6 = __readfsqword(0x28u);
  __printf_chk(1LL, "Please give me the key string:", a3);
  scanf("%s", &v5);

Solution:

测试有 3 列：id=1' order by 3#

有个提示select flag from flag

判断后端返回的前端显示的格式: id=-1' union select 1,2,3#，这里看出 1 号位不显示

之后经过一直测试，构造如下：id='union select 1,group_concat(flag),3 from flag#

key=os.urandom(2)*16这句话的意思是随机生成两个字符，然后复制 16 份，并衔接到这两个字符后面

Ubuntu 自带的 LibreOffice 软件的 Writter 里面的显示隐藏文字是没有用的，要 Microsoft Office Word 显示隐藏文字才行

之后把隐藏文字格式刷后才能复制，之后把备注的文字加到这段隐藏文字后面

base64 解码后又得到一堆文字，使用字频分析得到这段字符串actfplokmijnuhbygvrdxeszwq{}

中间部分填到大括号里就是 flag 了

Solution:

拿到文件，用 WinHex 查看发现他文件头是错误的，加了也没用

之后看到文件里面都是 0xA1，考虑可能是异或加密了，于是写脚本解密

exp如下：

with open(r'vip.m4a', 'rb') as rl:
    rl = list(rl.read())
    for i in range(0, len(rl)):
        rl[i] = chr(ord(rl[i]) ^ 0xa1)

rl = ''.join(rl)
with open(r'out.m4a', 'wb') as wl:
    wl.write(rl)

之后 flag 是听声音来填写的

Solution:

解压出一个压缩包和一个图片，压缩包是真加密所以先看图片

拖到 WinHex 里面可以发现最后有这么一段十六进制32 32 03 04 14 00 00 00

可知这后面是个压缩包，改成50 4b 03 04后，分离出压缩包

之后用 ARCHPR 或者 pkcrack 来分解，pkcrack 命令如下：

1
./pkcrack -C res.zip -c flag.txt -p flag.txt -P woo.zip -d ok.zip

解压出一个文件O_O和一个文件夹hint，hint文件夹里包含有两个文件：hh.jpg和pwd.txt

pwd.txt文件是 AAencode 加密，解密后明文为welcom3!

利用 steghide 来提取文件steghide extract -sf hh.jpg

想要flag吗？解出我的密文吧~

U2FsdGVkX1/7KeHVl5984OsGUVSanPfPednHpK9lKvp0kdrxO4Tj/Q==

base64 后发现前面是Salted__后面是乱码，猜测这个应该是 DES 加密一类

查看图片备注可以发现密钥为@#$%^&%%$)，经过 des 解密后得到字符串think about stegosaurus

O_O文件看内容有 py，猜测是 pyc 文件，所以使用 stegosaurus 进行解密，使用命令：

1
python3 -m stegosaurus ./workspace/123.pyc -x

Flag:
