Name Current Setting Required Description Module options (exploit/unix/webapp/php_include): ![]() From here, we can take a look at the settings: msf exploit(unix/webapp/php_include) > options Now type use exploit/unix/webapp/php_include to load the module. We will be using the php_include module locate it by entering search php_include. We will need the cookie information containing the security level and session ID in just a bit.įire up Metasploit by typing msfconsole in the terminal. When the page loads, we can see the text from our test file, indicating that this page is indeed vulnerable to RFI. Go to the "File Inclusion" page in DVWA, and replace the page being requested with the path of our test file being hosted on Kali. In order to check if an RFI vulnerability exists, we can simply ask the web application in question to retrieve the file we created earlier. service apache2 restart Step 2: Check for RFI Now, restart Apache and we should be good to go. On our Kali machine, create the file in /var/Enter some text, like "Vulnerable to RFI!" and save the file. Next, we need to create a test file to check for RFI. Finally, restart the Apache server by entering the following command: sudo /etc/init.d/apache2 restart Press Ctrl-X, Y, and Enter to save the file. Press Ctrl-W to search for the string "allow_url," and ensure that allow_url_fopen and allow_url_include are both set to On. These settings can be found in the php.ini file, so let's edit it to make sure they are enabled with: sudo nano /etc/php5/cgi/php.ini The allow_url_fopen option allows access to files on remote hosts or servers, while the allow_url_include option allows a remote file to utilize a URL rather than a local file path. Set the security level to low.īack on Metasploitable, we need to make sure a couple settings are enabled in the PHP configuration file for demonstration purposes. Next, on Kali, open DVWA in the browser and navigate to the "DVWA Security" tab. First, start Metasploitable and log in using msfadmin as the credentials. Step 1: Initial Setupīefore we get started, we need to configure a few things in order for this attack to be successful. In this guide, we will be exploiting an RFI vulnerability to get a command shell on the target system. This type of vulnerability presents itself most commonly in PHP applications, but it can also be found in ASP, JSP, and other technologies. RFI occurs when the path of a file taken as input is not properly sanitized, allowing an external URL to be processed over HTTP. Don't Miss: How to Manipulate User Credentials with a CSRF Attack.The file can be dynamically processed in a variety of ways, including code execution on the server, disclosure of sensitive information, and client-side code execution. Remote file inclusion (RFI) is a type of vulnerability found in web applications that allows an attacker to supply a remote file to the application. Kali Linux and the Metasploit Framework will serve as the tools of attack. Today, we will be using DVWA, a vulnerable web application included with the Metasploitable 2 virtual machine, as the target. For this reason, RFI can be a promising path to obtaining a shell. When a web application permits remotely hosted files to be loaded without any validation, a whole can of worms is opened up, with consequences ranging from simple website defacement to full-on code execution. l, -list List a module type.A simple security flaw can allow an attacker to gain a strong foothold with little effort on their part. payload-options List the payload's standard options Specify a '-' or stdin to use custom payloads Contact This site uses Just the Docs, a documentation theme for Jekyll.Common Metasploit Module Coding Mistakes.Work needed to allow msfdb to use postgresql common.Java Meterpreter Feature Parity Proposal.Guidelines for Accepting Modules and Enhancements.Guidelines for Writing Modules with SMB.How to write a module using HttpServer and HttpClient.How to send an HTTP request using Rex Proto Http Client.How to Send an HTTP Request Using HttpClient.Definition of Module Reliability Side Effects and Stability.How to check Microsoft patch levels for your exploit.Setting Up a Metasploit Development Environment.How to get Oracle Support working with Kali Linux.Information About Unmet Browser Exploit Requirements.The ins and outs of HTTP and HTTPS communications in Meterpreter and Metasploit Stagers.How to get started with writing a Meterpreter script.How to use a reverse shell in Metasploit.How to use a Metasploit module appropriately.RBCD - Resource-based constrained delegation.Keytab support and decrypting wireshark traffic.Get Ticket granting tickets and service tickets.Kerberos login enumeration and bruteforcing.Attacking AD CS ESC Vulnerabilities Using Metasploit. ![]()
