If you navigate to a HTTP website such as Burp will pick it all up:īurp will hold the proxied request until you either stop intercepting or click the forward button. Hooorrraaaayyy, we now have Burp Suite intercepting any traffic we generate through the browser. Make sure your checkbox for running is ticked. You will find if you open Burp Suite, click Proxy and then option, there will be a proxy listener with these details: What you are doing now is proxying all of your web traffic through your local machine that is being intercepted by anything that is listening.

Select Manual proxy configuration and copy the same config as me. On Firefox, open the preferences (about:preferences#general) and scroll to the bottom where you can see Network Settings then click on Settings. Other browsers will work, just have to find the correct browser setting. Now we have Burp installed we need to get it to intercept our traffic. You should be presented with the following interface: One you have Burp installed open the application. Configure the TLS (self-signed) certificate for HTTP S interceptingĭownload Burp from here (make sure you have Java installed too).Configure the browser to intercept all our traffic for inspection.

In this set of tutorials we will go through how to set up Burp to intercept traffic on your web browser. This binary can then be executed with the -p flag to escalate to root: ConclusionĮven though this box doesn’t bring anything new to the table, it is definitely a good way to practice and consolidate your web application penetration testing skills when planning to take on the OSCP exam.Burp Suite (referred to as Burp) is a graphical tool for testing web application security. GTFOBins explains in great detail how this can be exploited to escalate privileges to root:įollowing the same steps outlined in GTFOBins to create a SUID bash binary When checking for SUID binaries, /bin/systemctl stands out as it is not a standard SUID binary: It appears this worked, as a reverse shell connection has been established: Privilege Escalation When navigating to the uploaded shell which is in the /uploads directory, this should connect to the listener and grant a reverse shell The next step is to set up a Netcat listener, which will catch our reverse shell when it is executed by the victim host, using the following flags: phtml extension will work, judging by the “Success” response When the intruder attack has finished running, this shows the. Uploading a new file, but this time capturing the request using Burp SuiteĬonfiguring an intruder attack using the word list previously created in order to determine which extensions might work: php extension is not allowedĬreating a simple word list with a few common PHP related extensions to test out of any of them will work:

When navigating to the /internal page, it takes to a file upload page: File Upload ExploitationĬopying a PHP reverse shell to the working directory and updating the IP address and port based on the local machine

-t to specify the number of concurrent threadsĪfter a few minutes an “/internal” entry was found:.

-x to specify the extensions to enumerate.

dir to specify the scan should be done against directories and files.

The next step is to run a scan to find hidden files or directories using Gobuster, with the following flags: The first thing to do is to run a TCP Nmap scan against the 1000 most common ports, and using the following flags: This was one of the first rooms and it involved attacking a web application exploiting a file upload functionality, bypassing file extension whitelisting, and exploiting a SUID binary to escalate privileges. This room is part of the TryHackMe’s Offensive Pentesting learning path, which is something a lot of people use when preparing for their OSCP exam.
