Just finished this one too.. using my own common sense, but I didnt learn anything from it. I didnt even know I passed the mission till I tried to reinject data and it said "Youve already passed this mission,"move on" The injection caused the server to say it cant handle the request..? Thats all

Code: Select all
void blah(char *str) { char lol[200]; strcpy(lol, str); }

Look at 'char lol[200]' The answer is right there. (Obviously the answer is not 'char lol[200]' )

I'm sure this is about as helpful as someone can be without giving the answer away, but I still need a little push in the right direction. Is it a C command we enter in the box?

This is a program that asks for input, you give the input. The char array can hold 200 characters. Your goal is to crash the program. Can you figure it out now?

I managed to repeat your error if I went a little overboard on breaking the function, but it worked if I didn't do too much extra.

I believe he's saying that if he did more than was required for the challenge that he also got the error message but that it worked if he simplified it.

Some people look at the glass half full, some half empty. I prefer to fill it till it spills. . :mrgreen:

..what's it take to make this one spill?

Pretty much sums up this challenge

Ok people, let me give you some hint.
str is a pointer to a char. Since it's pointer it means that it can allocate as much memory as it needs from a free space unlike a lol which is a static array of 200 characters.
I think that this is more than good hint to answer your question.
Now use logic.
