在/home/daedalus/supercow
目錄下,有一支會印*.cow
內容的程式,說不定我們可以拿它來看flag.txt
- 把
flag.txt
更名成flag.cow
- 有權限問題,flag.txt無法直接更名
- 題目給的參考資料,提供了解決方法
- 創一個叫作flag.cow的symbolic link指到flag.txt就行了
$ ln -s flag.txt flag.cow
ln: failed to create symbolic link 'flag.cow': Permission denied
$ ln -s /home/daedalus/flag.txt /home_users/pico62895/flag.cow
$ ./supercow /home_users/pico62895/flag.cow
