Hack the Freshly VM (CTF Challenge)

Here we come with a new article which will all be about a penetration testing challenge called FRESHLY. The goal of this challenge is to break into the machine via the web and find the secret hidden in a sensitive file. It’s an easy lab… let’s get started with it and access it.

Breaching Methodology

  • Network Scanning (Nmap)
  • Recon (Nikto)
  • Login Form Based SQL Injection
  • Abusing wordpress
  • Generate PHP Backdoor (Msfvenom)
  • Upload and execute a backdoor
  • Reverse connection (Metasploit)
  • Take root access

Let’s Start!!

So to start with it firstly we have to find out the IP of FRESHLY. For that type the netdiscover command in terminal of Kali. It will show each IP present in our network.

Now we have target IP: so let’s scan it with aggressive scan (-A).

This shows all open ports: 80, 8080, 443.

As we can see 80 port is open so we will open target IP in our browser to find out what’s in there as our next clue.

Next we will apply nikto command to it. Nitko command will help us to gather information like its files and all the other major stuff that we ought to know about our target. So, therefore, type: nikto -h [host URL].

After scanning it shows that there is a login.php page found. So open it in a browser with target IP

Since we don’t know the exact username and password therefore we have used SQLMAP for login form based injection for retrieving the database name and login credential by executing following command.

From sqlmap result we came to that the name of database could be“wordpress8080”, so now using sqlmap again fetch username and password from that database i.e. wordpress8080

Alright we have achieved our first step by finding out user and password for wordpress.

User = admin

Password = SuperSecretPassword

Earlier we have already found out our open ports so use one of not used ports to open in browser ie.8080

Cool…See what you have got…. Now click on this link and you are all set for further result.

Candy goodness!!!!!  It’s our wordpress page. So let’s get on to other step by opening wordpress login page and entering the credentials we found out i.e.

User= admin

Password= SuperSecretPassword

Once you have logged in, make the malicious file that you got to upload in it. Generate code through msfvenom command:

Side by side in other terminal open metasploit and run multi handler.

From generated php raw file copy the code from <?php to die(). As we want to read a file on the system, let’s put some PHP code in the theme: We go to Appearance -> themes -> 404.php and add some PHP code in order to execute it.

Meanwhile, return to the Metasploit terminal and wait for the metepreter session by exploiting multi handler.

From given below image you can observe Meterpreter session1, now start penetrating for accessing root privilege. Then to access proper TTY shell we had import python one line script by typing following:

For getting root access account credential reuse from the WordPress admin password SuperSecretPassword that allowed su – to escalate privileges.
