The machine is VirtualBox as well as VMWare compatible. The DHCP will assign an IP automatically. You’ll see the IP right on the login screen. You have to find and read the flag which is present in /root/ If you’ve done djinn1 then you’ll notice some kind of similarity in services also a continuation in the storyline.

I try dirb scanning but I didn’t see useful directory We used the go buster tool for directory Bruteforce. and we find two pages genie and wish

I opened the /genie page. URL It is showing a message ( It’s not that hard )

Privilege Escalation

I found a creds.txt file cat command to we see the Nitish user and password I move on next step switch user using su command

we see blank shell now import python3 spawn shell using this command

checking Sudo rights of the user Nitish using the command

We found that the user Nitish can execute the genie binary without any password for user sam. using this command we successfully managed or get a shell of user sam

I again tried to enumerate the Sudo Permissions. for user sam As we can see user sam can execute the command /root/logo as root
