Intentamos ejecutar comandos pero no nos permites, buscaremos vulnerabilidades con searchsploit:
Funciono el modulo y estamos en la maquina como root, buscamos las Flags:
//
script /dev/null -c bash
root@lame:/home# ls
ftp makis service user
root@lame:/home# cd user
root@lame:/home/user# ls
root@lame:/home/user# cd ..
root@lame:/home# cd makis
root@lame:/home/makis# ls
user.txt
root@lame:/home/makis# cat user.txt
3493cdfeea702375fa941436919261ff
Ahora buscamos la flag de ROOT:
root@lame:/home/makis# cd /root
root@lame:/root# ls
Desktop reset_logs.sh root.txt vnc.log
root@lame:/root# cat root.txt
