Question

I have been looking quite a bit into exploiting recently. I have been googling alot and i managed to find DVL (Damn Vulnerable Linux) and Metasploitable but for some reason the exploits i scan them to have (with Nessus) do not really work. So now i have decided to try on a smaller scale.. I was wondering if anyone knows how to write a vulnerable program for Windows (potentially buffer overflow prone?) in maybe C or even ruby (im not sure about this one since it is an interpreted language) that can be exploited in ruby or python?

Any input would be greatly appreciated regarding this “project” 🙂

Thanks in advance,

Phil Baker

In Ruby an easy way to make a system vulnerable is by running text input from users in an eval.

bad_code = "system('rm -rf /users')"
eval(bad_code)
