Burp Suite is an incredible suite of tools that can help find vulnerabilities and misconfigurations in a web application. If you want to get more hands on with Burp I recommend TryHackMe’s Burp Suite Module. This concludes the basic guide for Repeater and Intruder. Using the credentials from Intruder we are able to verify the password for the admin was correct and we have successfully authenticated. This is a pretty good sign we got a hit during our brute force attack. Viewing the results we see one that sticks out with an HTTP Status of 302 and a much different Response size. Submit the attack by clicking the attack button and let’s see if we get a hit. Either load in the word list or copy and paste the passwords into the Payloads section. This password list if found under /Passwords. This time we will try the 500-worst-passwords.txt to see if we can find the admin password. With the parameters setup for the user to be admin and the password to be the target using a Sniper Attack Type we can now load in another word lists with SecLists. With Burp Suite running and FoxyProxy enabled we can capture a post request by attempting default credentials with admin/admin. If you are interested in working along, fire up Brute It on TryHackMe and navigate to the /admin page. Using the TryHackMe room Brute It we can get practice using Burp Suite Intruder to perform a brute force attack. Let’s take a look at one more example using Intruder to perform brute force password attacks on an administrative login. This was a good example of what Intruder and a good word list can do. The combination of Burp Suite intruder and SecList word lists for LFI allows us to not only to have a POC for /etc/passwd, but other Linux files that were read. It turns out that the parameter is indeed vulnerable to Local File Inclusion. While Intruder is cycling through the word list we can view Responses that have a vastly different Length to see if anything is interesting pops up. In SecLists this is stored in Fuzzing/LFI.īurp Suite Community Version will throttle the speed at which the fuzzing is happening, but we will quickly see some results come back from our attack. We can copy and paste the values of file LFI-Jhaddix.txt into the Payloads Options section. Because the parameter appears to be loading in a file, it would be a good guess to try for Local File Inclusion (LFI). Here we can insert our word list values from our SecLists. In this case we want to highlight the teamshare.php value. Sending the request to Intruder, we can highlight the parameter we want to fuzz. SecLists offers lists for command-injection, SQL Injection, XSS, Local File Inclusion (LFI), passwords, word lists for directory/file brute forcing, extensions, and much more. I encourage you to review and look over these word lists and see which ones can help you in a particular moment. SecLists offers a variety of fantastic word lists that we can use to Fuzz the parameter. The next step is to use Intruder to fuzz the page parameter to see if it is vulnerable. We can then tinker with the page parameter, change the Request to a Post Request, mess with the User-Agent, etc, to see if the application will display any errors or useful information in the Response. Next we can forward this request to Repeater in order to do some analysis. With Burp Suite we can access the Proxy Tab and then the HTTP History Tab and “Add to scope” to ensure only this applications traffic is captured with Burp Suite.Ĭlicking the Place Holder Link loads a new page with a page parameter in the URL. This will set up the section to perform our first attack. In the /etc/hosts file I will add an entry for. I will be cheating a bit to get to the fuzzing section of Team. With Burp Suite running and Team Room setup via TryHackMe we can get testing. Using TryHackMe’s Team Room, we can have an environment set up to do testing. Here is a basic setup on how I have FoxyProxy setup and leveraging Burp Suites port 8080. FoxyProxy helps make managing the proxy simple, as it can be enabled and disabled through the browser. If you are not familiar, Burp Suite needs to have a proxy setup between the browser and target application. I will also be using FoxyProxy to proxy the traffic through. I highly encourage looking into the Burp Suite Academy for labs on Burp Suite as well to get more hands on experience. I will use a TryHackMe Free room called Team Room and a room called Brute it to help set up the testing targets. We will utilize Burp Suites Repeater and Intruder functionality along with word lists from SecLists. In this guide I will show you how to leverage the free (community) edition to help find vulnerabilities in web applications. Burp Suite is a set of tools used to perform Web Application Pentesting.
