PORT 80

I didn’t find any directories through gobuster

PORT 139/445 (SMB)

There is smb on the box so lets enumerate the shares and if we can read one of them

There are three shares and hopefully we can read share

html is a directory so try to upload a reverse shell there and see if it gets uploaded

Perfect so by looking at index.html it seems this is a storage of web server

On stabilizing the shell and looking for SUID we find gdb which is not commonly set as SUID so go to GTFOBINS to see if we can escalate our privileges

We are root !!!
