    This Windows box is named Metallus. Lets see if we can get root on this one. Reconnaissance Starting with some initial enumeration. Nmap scan -Pn to ignore ping check, -sV to check versions, -sC to run all scripts, and -oA output results in all formats.

    All addresses will be marked 'up' and scan times will be slower. Starting Nmap 7. Nmap done: 1 IP address 1 host up scanned in Lets kicked off a full TCP scan while checking out these services in more detail. SSH on port looks interesting, but even better is a web server on Immediately noticeable is the build number that is installed.

    Lets take note of this. Before digging into the build number lets look up default credentials for this application. Lets give that a shot. So this opens up some possibilities, but there is tons to dig into.

    Before digging into the application lets go back and check on that build number we enumerated. We have one exploit that matches the build exactly and it claims to allow remote code execution. Lets check out the exploit. From the title we see the exploit requires authentication. This shows the exploit generates the payload, exploits the service and runs the payload. Function flow: 1. Get initial cookie 2. Get valid session cookie by logging in 3. Get base directory of installation 4.

    Generate a malicious JAR file 5. Attempt to directly upload JAR, if success, jump to 7 6. Execute task 8. Delete task for cleanup 9.

    None in this one. Foothold Alright lets give this a shot. All rights reserved. Execute exploit. Checking back on the netcat listener. Just navigate to the Administrator desktop and grab the flag. Conclusion In conclusion, the machine ended up having a simple out of date application that lead to remote code execution.

    The exploit was easy to use and was well documented to help the user know what to expect and what was happening during execution. Keep your applications up to date and change those default credentials. Until next time, stay safe in the Trenches of IT.

    Pivoting to “unreachable” machines in another subnet (no Metasploit)

    Metasploit with Docker and Kubernetes Last Updated on by Kalitut Leave a Comment Running Metasploit with Docker and Kubernetes This article is intended to make it easy to build a penetration test environment without complicated settings if Docker and Kubernetes are introduced. Since GitHub also has a Dockerfile of Metasploit images etc. Also, this time, an —rm option is added at the time of execution so that extra containers do not remain.

    Since you are currently logged in to the attack container, msfconsole entering the command will launch the Metasploit console. You now know a variety of information, such as available ports, services and OSs that are likely to be running there.

    By the way, since these are naturally stored in the database of the container currently logged in, you can also view the information by sending a query from SQL. In addition, when there are multiple entries in the database, hostsyou can also select an attack target that meets the conditions by using a command or the like. This seems to be something that automates the task by writing the task which is done many times in the resource file.

    This time I do not particularly attack many times, but I think that you can use it with Kubernetes, which will be described later, so I would like to attack using resource files. Also, as we know from Nmap results that the ftp service is running on port 21, we will use the famous module for ftp this time. Only the module used and the target IP and execution instruction of the attack.

    By the way, in the sessions command part, you can specify an instruction which you want to execute as an -i option for any session -c. It can be confirmed that this attack has gained root privileges. You can also load resource files by adding options to the msfconsole command and -r turn -q off the banner by adding options.

    Please log in to Metasploitable. The hacked. The penetration test using Docker is above. By default, one Metasploit Pod and three Metasploitable Pods are created, but you can spec. This completes the environment construction using Kubernetes. Kubernetes can perform penetration tests in the same way as Docker showed.

    Thank you for reading so far! We hope that the content of this article will be useful for the penetration test assuming various situations.

    Port Scanning

    Set Version: Ubuntu, and to continue, click the Next button. Step 2: Now extract the Metasploitable2. Return to the VirtualBox Wizard now.

    Step 3: Set the memory size to MB, which is adequate for Metasploitable2. In order to proceed, click on the Create button. Step 5: Select your Virtual Machine and click the Setting button. Step 7: Bootup the Metasploitable2 machine and login using the default user name and Password: Username: msfadmin Password: msfadmin Scanning Process In this tutorial, we will walk through numerous ways to exploit Metasploitable 2, the popular vulnerable machine from Rapid7.

    Metasploitable is a Linux virtual machine that is intentionally vulnerable. This VM could be used to perform security training, evaluate security methods, and practice standard techniques for penetration testing.

    Step2: To establish a connection between the client and the server, a putty session will be generated that requires a login credential. Username: ignite Password: Port Redirection By default, ssh listen on port 22 which means if the attacker identifies port 22 is open then he can try attacks on port 22 in order to connect with the host machine. Therefore, a system admin chooses Port redirection or Port mapping by changing its default port to others in order to receive the connection request from the authorized network.

    SSH key pairs is another necessary feature to authenticate clients to the server. It consists of a long string of characters: a public and a private key. You can place the public key on the server and private key on the client machine and unlock the server by connecting the private key of the client machine. Once the keys match up, the system permits you to automatically establish an SSH session without the need to type in a password.

    Ssh-keygen is a tool for creating new authentication key pairs for SSH. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts. Thus, we will follow the steps for generating a key pair for authenticated connection. Now if you need to connect to the ssh server using your password username, the server will drop your connection request because it will authenticate the request that has authorized key.
