[WeChall] Training: Warchall - 7 Tropical Fruits

This is level 7 on the warchall box.
You can find the vulnerable binary + sourcecode in "/home/level/07_tropical_fruits/".
You can also view the source here.
Your mission is to exploit it, circumvent the ASLR protection and read a file in the name of the executable.

Good Luck!

GeSHi`ed C code for tropic7.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
void hint(){
        printf("Need to bypass aslr\n");
        exit(0);
}
void vulnfunc(char *input){
        char vulnbuf[300];
        memcpy(vulnbuf, input, strlen(input));
}
int main(int argc, char *argv[]){
        if(argc > 1)
        {
                vulnfunc(argv[1]);
        }        else
        {
                printf("%s <input>\n", argv[0]);
                return 1;
        }        return 0;
}
