MetaSploit tutorial for beginners
This MetaSploit tutorial for beginners is to be a starting guide for how to use MetaSploit. It assumes that you already have MetaSploit installed, or that you are running Kali / backtrack Linux.
The basic concept of how to use MetaSploit is as follows:
– Run msfconsole in your terminal
– Identify a remote host and add to the metasploit database
– Identify a vulnerability in the remote host that you wish to exploit
– Configure the payload to exploit the vulnerability in the remote host
– Execute the payload against the remote host
Once you have mastered this pattern, you can do most things within Metasploit. As this is a MetaSploit tutorial for beginners, I’ll walk you through the steps.
Start the database service
In Kali Linux Terminal:
service postgreqsql start # if this is the first time you are running metasploit, run the following: msfdb init # start metasploit using msfconsole msfconsole
or using the kali linux menu systm:
Exploitation tools > Metasploit
You will meet with the following prompt in your terminal:
This is msfconsole. Msfconsole is the main command line interface to MetaSploit. There are other interfaces available – GUI interfaces (armitage), and a web interface too (websploit). With msfconsole you can launch exploits, create listeners, configure payloads etc.
Getting help in metasploit
MetaSploit has lots of great documentation built in. Type help to get a basic list of commands.
help show will give you the help section for the show command.
help search will give you the help section for the search command.
If you get the error ‘Database not connected or cache not built’ use ‘db_status’ to see if the metasploit database connected. if not, start the postgresql database (instructions above) and re-start msfconsole. If ‘db_status’ reports ‘connected’ then run the ‘db_rebuild_cache’ command to rebuild your metasploit database cache.
#rebuild the database caches db_rebuild_cache
Identify a remote host
You can run nmap from inside msfconsole and save the output into the MetaSploit database.
db_nmap -v -sV host_or_network_to_scan[eg 192.168.0.0/24]
This is a handy way to get an initial list of remote hosts on your network. I have some other tips in this linux commands for networking article.
To show a list of all available port scanners:
More examples of port-scanning remote machines and saving the output into the MetaSploit database are here:
To list all the remote hosts found by your nmap scan:
To add these hosts to your list of remote targets
Pick a vulnerability and use an exploit
Once you have performed an operating system fingerprint (or you have identified the application running on the remote host, eg by imporing nessus results into metasploit) and know what your remote hosts operating system is (using nmap, lynix, maltego, wp-scan, etc) you can pick an exploit to test. rapid7 have an easy way to find exploits. There is also a way to search within msfconsole for various exploits:
search type:exploit search CVE-XXXX-XXXX search cve:2014 search name:wordpress
See metasploit unleashed for more examples of the search command
Once you have found a suitable exploit to use against the vulnerability in the remote host, issue the following command into msfconsole:
eg: use exploit/unix/webapp/php_wordpress_total_cache
From this point on, the available options change based on the exploit you are using, but you can get a list of the available options with:
For a list of the available targets:
Configure the exploit
In MetaSploit each exploit has a set of options to configure for your remote host:
This gives a list. You need to set the options with ‘yes’ next to them.
set RHOST 192.168.0.15
If you issue the ‘hosts -R’ command then you will see that the remote hosts parameters are already filled in for you.
Execute the exploit against the remote host
If metasploit is successful in exploiting the vulnerability, you will know. If not, then try again with a different exploit, or aim for an alternative vulnerability ;)
Thats the basics covered! I hope you enjoyed my metasploit tutorial for beginners
