Sunset: Vulnhub Walkthrough
Sunset is another CTF challenge which is meant for the beginner level and credit for which goes to the author “Whitecr0wz.” In this machine, our target is to find the flags and access the root. So, let’s get started. You can download this lab through the link given below-
Penetration Testing Methodology
- Login through ftp
Exploitation & Privilege escalation
- Connect through ssh
- Exploiting sudo rights
Like we always do this is the initial step, so as usual, we are going to execute netdiscover command to identify the host ip.and we have found that the host i.p 192.168.1.153 is up.
So, let’s move further towards our next step which is to identify the port status and where we will use Nmap after which we got to know that port no.21 and 22 are open and we can access ftp with the anonymous user. So, let’s move ahead.
nmap -A 192.168.1.153
As expected, we tried to login ftp with an anonymous user and we have successfully done that and after that, we got a file there by the name “backup”. We will first save that file in our system and then open the file and got the five users’ hashes.
ftp 192.168.1.153 ls get backup
So, we will copy those hashes and save it in a file named hash and there after we will take the help of john the ripper tool to crack those hashes where we have found the password “cheer14” for the user “sunset”, so our next step will be to connect through ssh with this user and password.
Exploitation and Privilege Escalation
We have logged in through ssh with the user sunset and we found the file there by the name user.txt inside which we got again the hash file.
Now we will check whether which file has sudo permissions and we found that ed is the member of sudoers.
So, we will execute !/bin/sh command and we will get the root access.
After we logged in as root there, we again found a file named flag.txt; opening which we will get our final flag. Hence, we have successfully got the root access and solved the CTF.
ssh email@example.com ls sudo –l sudo /usr/bin/ed ! /bin/sh cd /root ls cat flag.txt
