Tryhackme burp suite walkthrough8/31/2023 Next to the "Send to Repeater" option you can see a shortcut of CTRL-R Q4: Which shortcut allows us to forward the request to Repeater?Ī: Hitting right-click in the Intercept tab where the request is, we can see a list of available options. Change back to Burp Suite and we will see we have a request waiting in the " Intercept" tab. The page appears to be continuously loading. Return to the browser and navigate to the website hosted on the VM we deployed. In Burp Suite, navigate to the " Intercept" sub-tab of the proxy section and turn " Intercept On" By default, we can see it is using 127.0.0.1:8080 What is it?Ī: We can check this by going to the Proxy tab and then the sub-interface of options. Q2: By default, Burp Suite proxy listens on only one interface. Q9: Last but certainly not least, which tool allows us to modify Burp Suite via the addition of extensions?Last but certainly not least, which tool allows us to modify Burp Suite via the addition of extensions? Q8: With four modes, which tool in Burp can we use for a variety of purposes such as field fuzzing? Q7: Simple in concept but powerful in execution, which tool allows us to reissue requests? Q6: Which tool allows us to redirect our web traffic into Burp for further examination? ![]() Q5: Encoding or decoding data can be particularly useful when examining URL parameters or protections on a form, which tool allows us to do just that? Q4: While only available in the premium versions of Burp Suite, which tool can we use to automatically identify different vulnerabilities in the application we are examining? Q3: Which tool can we use to set the scope of our project? Q2: What tool could we use to analyze randomness in different pieces of data such as password reset tokens? 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.Q1: Which tool in Burp Suite can we use to perform a 'diff' on responses and other pieces of data? 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.
