Flag1 and Flag2

Basically flag1.txt and flag2.txt were in luciafer documents. Just move to that folder and use cat flag1.txt:

flag{cb07e9d6086d50ee11c0d968f1e5c4bf1c89418c}
and cat .flag2.txt:
flag{728ec98bfaa302b2dfc2f716d3de7869f3eadcbf}

Flag3

Then looking for SUID bit files with find / -perm /4000 2> /dev/null we found something funny: /usr/local/bin/ouija

That executable was owned by root and has the SUID bit set so it will be run as him. This executable will take the input and append /root/ to it, basically to read a file from that folder. Using relatives paths we were able to read every file we want with it.

Just use ouija ../home/spookyboi/Documents/flag3.txt and get your flag

flag{445b987b5b80e445c3147314dbfa71acd79c2b67}

Flag4

Do you remember that ouija append the /root/ string to our input? Well we tried ouija flag4.txt and the flag appeared

flag{4781cbffd13df6622565d45e790b4aac2a4054dc}
