Ethical Hacking----1. For list of all metasploit modules, visit the Metasploit Module Library. An example of an SMB vulnerability is the Wannacry vulnerability that runs on EternalBlue. It shows that the target system is using old version of OpenSSL and had vulnerability to be exploited. First things first, as every good hack begins, we run an NMAP scan: Youll notice that Im using the v, -A and -sV commands to scan the given IP address. HTTP stands for HyperText Transfer Protocol, while HTTPS stands for HyperText Transfer Protocol Secure (which is the more secure version of HTTP). Anyhow, I continue as Hackerman. This document will continue to expand over time as many of the less obvious flaws with this platform are detailed. The security vendor analyzed 1.3 petabytes of security data, over 2.8 billion IDS events, 8.2 million verified incidents, and common vulnerabilities for more than 700 SMB customers, in order to compile its Critical . This page contains detailed information about how to use the auxiliary/scanner/http/ssl_version metasploit module. In our case we have checked the vulnerability by using Nmap tool, Simply type #nmap p 443 script ssl-heartbleed [Targets IP]. Education for everyone, everywhere, All Rights Reserved by The World of IT & Cyber Security: ehacking.net 2021. ): This module may fail with the following error messages: Check for the possible causes from the code snippets below found in the module source code. bird. these kind of backdoor shells which is categorized under [*] Accepted the first client connection [*] Accepted the second client connection [*] Command shell session 1 opened (192.168.99.128:4444 -> 192.168.99.131:60257) at 2012-05-31 21:53:59 -0700, root@ubuntu:~# telnet 192.168.99.131 1524, msf exploit(distcc_exec) > set RHOST 192.168.99.131, [*] Command shell session 1 opened (192.168.99.128:4444 -> 192.168.99.131:38897) at 2012-05-31 22:06:03 -0700, uid=1(daemon) gid=1(daemon) groups=1(daemon), root@ubuntu:~# smbclient -L //192.168.99.131, Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.20-Debian], print$ Disk Printer Drivers, IPC$ IPC IPC Service (metasploitable server (Samba 3.0.20-Debian)), ADMIN$ IPC IPC Service (metasploitable server (Samba 3.0.20-Debian)), msf > use auxiliary/admin/smb/samba_symlink_traversal, msf auxiliary(samba_symlink_traversal) > set RHOST 192.168.99.131, msf auxiliary(samba_symlink_traversal) > set SMBSHARE tmp, msf auxiliary(samba_symlink_traversal) > exploit. 'This vulnerability is part of an attack chain. This will bind the host port 8022 to the container port 22, since the digitalocean droplet is running its own SSHd, port 22 on the host is already in use.Take note of the port bindings 443450, this gives us a nice range of ports to use for tunneling. Metasploit basics : introduction to the tools of Metasploit Terminology. Porting Exploits to the Metasploit Framework.

This is done to evaluate the security of the system in question. Individual web applications may additionally be accessed by appending the application directory name onto http:// to create URL http:////. This is the action page, SQL injection and XSS via the username, signature and password field, Contains directories that are supposed to be private, This page gives hints about how to discover the server configuration, Cascading style sheet injection and XSS via the color field, Denial of Service if you fill up the logXSS via the hostname, client IP, browser HTTP header, Referer HTTP header, and date fields, XSS via the user agent string HTTP header. Other examples of setting the RHOSTS option: Here is how the scanner/http/ssl_version auxiliary module looks in the msfconsole: This is a complete list of options available in the scanner/http/ssl_version auxiliary module: Here is a complete list of advanced options supported by the scanner/http/ssl_version auxiliary module: This is a list of all auxiliary actions that the scanner/http/ssl_version module can do: Here is the full list of possible evasion options supported by the scanner/http/ssl_version auxiliary module in order to evade defenses (e.g. Chioma is an ethical hacker and systems engineer passionate about security. Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888 List of CVEs: - This module exploits unauthenticated simple web backdoor shells by leveraging the common backdoor shell's vulnerable parameter to execute commands. As result, it has shown the target machine is highly vulnerable to Ms17-010 (eternal blue) due to SMBv1. Of course, snooping is not the technical term for what Im about to do. The initial attack requires the ability to make an untrusted connection to Exchange server port 443. In addition to these system-level accounts, the PostgreSQL service can be accessed with username postgres and password postgres, while the MySQL service is open to username root with an empty password. However, to keep things nice and simple for myself, Im going to use Google. Step 4: Integrate with Metasploit. So, lets try it. The Exploit Database is a repository for exploits and proof-of-concepts rather than advisories, making it a valuable resource for those who need actionable data right away. Let's move port by port and check what metasploit framework and nmap nse has to offer. vulnerabilities that are easy to exploit. LHOST serves 2 purposes : With-out this protocol we are not able to send any mail. Detect systems that support the SMB 2.0 protocol. Supported architecture(s): cmd So, last time I walked through a very simple execution of getting inside an office camera using a few scripts and an open RTSP port. This article discusses OT security and why it is essential for protecting industrial systems from cyberattacks. The Secure Sockets Layer (SSL) and the Transport Layer Security (TLS) cryptographic protocols have had their share of flaws like every other technology. When we access, we see the Wazuh WUI, so this is the IP address of our Wazuh virtual machine. The SMB port could be exploited using the EternalBlue vulnerability, brute forcing SMB login credentials, exploiting the SMB port using NTLM Capture, and connecting to SMB using PSexec. Pentesting is used by ethical hackers to stage fake cyberattacks. CVE-2018-11447 : A vulnerability has been identified in SCALANCE M875 (All versions). Nmap is a network exploration and security auditing tool. Were building a platform to make the industry more inclusive, accessible, and collaborative. Step 1 Nmap Port Scan. A file containing a ERB template will be used to append to the headers section of the HTTP request. Module: auxiliary/scanner/http/ssl_version Many ports have known vulnerabilities that you can exploit when they come up in the scanning phase of your penetration test. By default, Metasploitable's network interfaces are bound to the NAT and Host-only network adapters, and the image should never be exposed to a hostile network. Since port 443 is running, we open the IP in the browser: https://192.168.1.110. It can only do what is written for. This vulnerability allows an unauthenticated user to view private or draft posts due to an issue within WP_Query. modules/auxiliary/scanner/http/ssl_version.rb, 65: vprint_status("#{peer} does not accept #{ssl_version}"), #14696 Merged Pull Request: Zeitwerk rex folder, #8716 Merged Pull Request: Print_Status -> Print_Good (And OCD bits 'n bobs), #8338 Merged Pull Request: Fix msf/core and self.class msftidy warnings. Target service / protocol: http, https. At this point, Im able to list all current non-hidden files by the user simply by using the ls command. Check if an HTTP server supports a given version of SSL/TLS. From the shell, run the ifconfig command to identify the IP address. During a discovery scan, Metasploit Pro . If we serve the payload on port 443, make sure to use this port everywhere. The first and foremost method is to use Armitage GUI which will connect with Metasploit to perform automated exploit testing called HAIL MARY. Normally, you can use exploit/multi/http/simple_backdoors_exec this way: Using simple_backdoors_exec against multiple hosts. Disclosure date: 2014-10-14 However, the steps I take in order to achieve this are actually representative of how a real hack might take place. Dump memory scan, will make 100 request and put the output in the binary file dump.bin: python heartbleed-poc.py -n100 -f dump.bin example.com. Note that any port can be used to run an application which communicates via HTTP/HTTPS. TCP is a communication standard that allows devices to send and receive information securely and orderly over a network. This article explores the idea of discovering the victim's location. The list of payloads can be reduced by setting the targets because it will show only those payloads with which the target seems compatible: Show advanced To have a look at the exploit's ruby code and comments just launch the following . It does this by establishing a connection from the client computer to the server or designated computer, and then sending packets of information over the network. The -u shows only hosts that list the given port/s as open. Spaces in Passwords Good or a Bad Idea? Scanning ports is an important part of penetration testing. A brief overview of various scanner HTTP auxiliary modules in the Metasploit Framework. But it looks like this is a remote exploit module, which means you can also engage multiple hosts. To exploit this vulnerability, simply add ?static=1 after the domain name so it reads: Ive now gained access to a private page on WordPress. How to hack Android is the most used open source, Linux-based Operating System with 2.5 billion active users. Anonymous authentication. Supported architecture(s): - Additionally three levels of hints are provided ranging from "Level 0 - I try harder" (no hints) to "Level 2 - noob" (Maximum hints). EH Academy is the brainchild of Ehacking, which has been involved in the field of training since the past Five years and continues to help in creating professional IT experts. It's a UDP port used to send and receive files between a user and a server over a network. The Exploit Database is a repository for exploits and proof-of-concepts rather than advisories, making it a valuable resource for those who need actionable data right away. In order to check if it is vulnerable to the attack or not we have to run the following dig command. Have you heard about the term test automation but dont really know what it is? In our Metasploit console, we need to change the listening host to localhost and run the handler again. But while Metasploit is used by security professionals everywhere, the tool can be hard to grasp for first-time users. Conclusion. The make sure you get different parts of the HEAP, make sure the server is busy, or you end up with repeat repeat. This particular version contains a backdoor that was slipped into the source code by an unknown intruder. unlikely. Simply type #nmap -p 443 -script ssl-heartbleed [Target's IP] It shows that the target system is using old version of OpenSSL and had vulnerability to be exploited. From our attack system (Linux, preferably something like Kali Linux), we will identify the open network services on this virtual machine using the Nmap Security Scanner. For the lack of Visio skills see the following illustration: To put all of this together we need a jump host that can receive our SSH session.Luckily we live in the great age of cloud services and Docker, so an approach to that is to run a droplet on digitalocean, possibly using the great investiGator script to deploy and run an SSH server as a Docker service and use that as a very portable and easily reproducible way of creating jump hosts. To check for open ports, all you need is the target IP address and a port scanner. Having port 80 and 443 and NAT'ed to the webserver is not a security risk in itself. dig (domain name) A (IP) If the flags in response shows ra which means recursive available, this means that DDoS is possible. Kali Linux has a few easy tools to facilitate searching for exploits Metasploit and Searchsploit are good examples. How to Hide Shellcode Behind Closed Port? We'll come back to this port for the web apps installed. For the purpose of this hack, Im trying to gather username and password information so that Im able to login via SSH. So, with that being said, Ill continue to embrace my inner script-kiddie and stop wasting words on why Im not very good at hacking. Windows User Mode Exploit Development (EXP-301) macOS Control Bypasses (EXP-312) . Although a closed port is less of a vulnerability compared to an open port, not all open ports are vulnerable. Infrastructure security for operational technologies (OT) and industrial control systems (ICS) varies from IT security in several ways, with the inverse confidentiality, integrity, and What is an Operational Technology (OT)? Readers like you help support MUO. If a web server can successfully establish an SSLv3 session, So I have learned that UDP port 53 could be vulnerable to DNS recursive DDoS. As a penetration tester or ethical hacker, it is essential you know the easiest and most vulnerable ports to attack when carrying out a test. So, next I navigate to the host file located in /etc/hosts, and add 10.10.11.143 office.paper to my list of trusted hosts: I now have access to the website which displays nothing more than the most basic of information. Solution for SSH Unable to Negotiate Errors. There are a couple of advantages to that approach, for one it is very likely that the firewall on the target or in front of it is filtering incoming traffic. If you execute the payload on the target the reverse shell will connect to port 443 on the docker host, which is mapped to the docker container, so the connection is established to the listener created by the SSH daemon inside the docker container.The reverse tunnel now funnels the traffic into our exploit handler on the attacker machine, listening on 127.0.0.1:443. Currently missing is documentation on the web server and web application flaws as well as vulnerabilities that allow a local user to escalate to root privileges. From the DVWA home page: "Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is damn vulnerable. An example of an ERB template file is shown below. Operational technology (OT) is a technology that primarily monitors and controls physical operations. shells by leveraging the common backdoor shell's vulnerable By this, I mean that the hack itself is performed on a virtual machine for educational purposes, not to actually bring down a system. The page tells me that the host is not trusted, so at this point, I remember that I need to give host privileges to the domain Im trying to access demonstrated below: Im now inside the internal office chat, which allows me to see all internal employee conversations, as well as the ability to interact with the chat robot. The problem with this service is that an attacker can easily abuse it to run a command of their choice, as demonstrated by the Metasploit module usage below. TCP ports 512, 513, and 514 are known as "r" services, and have been misconfigured to allow remote access from any host (a standard ".rhosts + +" situation). It can be exploited using password spraying and unauthorized access, and Denial of Service (DoS) attacks. Coyote is a stand-alone web server that provides servlets to Tomcat applets. Curl is a command-line utility for transferring data from or to a server designed to work without user interaction. through Burp Suite: If the module has no username/password options, for instance to log into an admin portal of a web application etc, then the credentials supplied via a HTTP URI will set the HttpUsername/HttpPassword options for HTTP Basic access Authentication purposes. So, by interacting with the chat robot, I can request files simply by typing chat robot get file X. These are the most popular and widely used protocols on the internet, and as such are prone to many vulnerabilities. It doesnt work. DNS stands for Domain Name System. Well, that was a lot of work for nothing. You can exploit the SSH port by brute-forcing SSH credentials or using a private key to gain access to the target system. Disclosure date: 2015-09-08 MetaSploit exploit has been ported to be used by the MetaSploit framework. This command returns all the variables that need to be completed before running an exploit. Target service / protocol: http, https Using simple_backdoors_exec against a single host. The Exploit session, shown in Figure 4, is the proof-of-concept Log4j exploit code operating on port 1389, creating a weaponized LDAP server. Try to avoid using these versions. The Metasploit Framework makes discovering, exploiting, and sharing vulnerabilities quick and relatively painless. 443/TCP - HTTPS (Hypertext Transport Protocol Secure) - encrypted using Transport Layer Security or, formerly, Secure Sockets Layer. SMB 2.0 Protocol Detection. At Iotabl, a community of hackers and security researchers is at the forefront of the business. The output of this Docker container shows us the username user and the password to use for connecting via SSH.We want to use privileged ports in this example, so the privileged-ports tag of the image needs to be used as well as root needs to be the user we connect as.On the attacker machine we can initiate our SSH session and reverse tunnels like so: More ports can be added as needed, just make sure to expose them to the docker host. This module is a scanner module, and is capable of testing against multiple hosts. This Exploitation is divided into 3 steps if any step you already done so just skip and jump to direct Step 3 Using cadaver Tool Get Root Access. The backdoor was quickly identified and removed, but not before quite a few people downloaded it. Many ports have known vulnerabilities that you can exploit when they come up in the scanning phase of your penetration test. Not necessarily. What I learnt from other writeups is that it was a good habit to map a domain name to the machine's IP address so as that it will be easier to remember. Good luck! Samba, when configured with a writeable file share and "wide links" enabled (default is on), can also be used as a backdoor of sorts to access files that were not meant to be shared. Active Directory Brute Force Attack Tool in PowerShell (ADLogin.ps1), Windows Local Admin Brute Force Attack Tool (LocalBrute.ps1), SMB Brute Force Attack Tool in PowerShell (SMBLogin.ps1), SSH Brute Force Attack Tool using PuTTY / Plink (ssh-putty-brute.ps1), Default Password Scanner (default-http-login-hunter.sh), Nessus CSV Parser and Extractor (yanp.sh). Sometimes port change helps, but not always. Heartbleed vulnerability (registered as CVE-2014-0160) is a security bug present in the older version of OpenSSL cryptographic library. Having now gathered the credentials to login via SSH, I can go ahead and execute the hack. If a port rejects connections or packets of information, then it is called a closed port. Metasploitable. The vast majority of vulnerabilities in ports are found in just three, making it theoretically easier for organizations to defend them against attack, according to Alert Logic.. Now the question I have is that how can I . Payloads. Its worth remembering at this point that were not exploiting a real system. We were able to maintain access even when moving or changing the attacker machine. $ echo "10.10.10.56 shocker.htb" | sudo tee -a /etc/hosts. Source code: modules/exploits/multi/http/simple_backdoors_exec.rb Metasploitable 2 Exploitability Guide. After the virtual machine boots, login to console with username msfadmin and password msfadmin. It can be used to identify hosts and services on a network, as well as security issues. 1619 views. Inspired by DVWA, Mutillidae allows the user to change the "Security Level" from 0 (completely insecure) to 5 (secure). We then performed lateral movement from the compromised host by utilizing the autoroute post exploitation module and routing metasploit traffic. Our security experts write to make the cyber universe more secure, one vulnerability at a time. TIP: The -p allows you to list comma separated port numbers. To configure the module . We will use 1.2.3.4 as an example for the IP of our machine. Version 2 of this virtual machine is available for download and ships with even more vulnerabilities than the original image. Everything You Must Know About IT/OT Convergence, Android Tips and Tricks for Getting the Most from Your Phone, Understand the OT Security and Its Importance. payload options accordingly: Next, run the resource script in the console: And finally, you should see that the exploit is trying against those hosts similar to the following Heartbleed is still present in many of web servers which are not upgraded to the patched version of OpenSSL. DVWA contains instructions on the home page and additional information is available at Wiki Pages - Damn Vulnerable Web App. Metasploit version [+] metasploit v4.16.50-dev-I installed Metasploit with. Name: HTTP SSL/TLS Version Detection (POODLE scanner) This bug allowed attackers to access sensitive information present on web servers even though servers using TLS secure communication link, because the vulnerability was not in TLS but in its OpenSSL implementation. Step 2 SMTP Enumerate With Nmap. And which ports are most vulnerable? This code will redirect the victim server to download and execute a Java class that is obtained from our Python Web Server running on port 80 above. On newer versions, it listens on 5985 and 5986 respectively. The most popular port scanner is Nmap, which is free, open-source, and easy to use. It depends on the software and services listening on those ports and the platform those services are hosted on. If you're unfamiliar with it, you can learn how to scan for open ports using Nmap.
