Stack Overflows for Beginners: 1 is designed and created by Jack Barradell-Johns.
  1. A series of challenges to test basic stack overflow skills, originally developed for the Sheffield University Ethical Hacking Society.

  2. Starting as level0 exploit a binary owned by the next user to get the flag.

  3. There are 5 flags to collect:

  4.     /home/level1/level1.txt
  5.     /home/level2/level2.txt
  6.     /home/level3/level3.txt
  7.     /home/level4/level4.txt
  8.     /root/root.txt

  9. Each flag is the corresponding users password, so once you exploit the binary owned by level1 and get the level1 flag, you can su to level1 and take on the next challenge

  10. To start boot the machine and login as:

  11.     username: level0
  12.     password: level0

  13. You'll find the first binary to exploit is: /home/level0/level1

  14. You may want to increase the resources allocated to the machine.

To avoid being a spoiler, the flags and exploit codes are not shown in the video.

The box has 5 flags to capture and they are all basic stack overflows challenges.

Level1 是送的

同埋是/home/level0/levelOne
及現在會 setuid, 唔駛 su

如果你咁做,就會失去很多樂趣了。

個設計不是這樣的。
