There are a lot of sloppy filters out there: check out what it is doing and see if you can bypass it. Something to check for: are your script tags being filtered or changed in some way? If they are being filtered or changed in some way, can you think of a way to bypass that filter? You can check the responses either in Burp Suite or by simply right clicking in your browser and viewing the source. If you do not see an alert pop up, that does not necessarily mean that it is not vulnerable to cross-site scripting. You could actually go out there on a lot of websites and find cross-site scripting by doing that, although you should of course never try to pentest a site without permission. If you see an alert pop up you just found cross-site scripting. Look at what happens when you try this (make sure it is URL encoded), and observe the response in a browser. BURP SUITE TRYHACKME HOW TOThere is a huge amount of information out there on how to find and exploit SQL injections and we have only scratched the surface.Ĭheck for cross-site scripting by entering the string we used in generating an alert box. If somebody is stopping you from doing something on a web application there is probably a reason for it, and if you can bypass that and find the reason for them to try to stop you from doing that, it is usually a great way in.Ī general note on injection attacks: always URL encode when putting characters into parameters since it never hurts but always helps.Ĭheck for SQL injections within the applications by trying special/reserved SQL characters, for example the apostrophe symbol, pound sign, dash, plus, parentheses, and so forth. Look for attempts at stopping the user from typing certain characters into text boxes since these are often good injection points. Is it using PHP, is there some kind of database, is it JavaScript heavy?įollowing from checking the obvious, we should look towards exploiting client-side controls that attempt to stop a user from doing something through parameters in GET or POST requests. Try to understand the technologies behind the application. Try to understand how requests and responses are being passed back and forth. Look at HTTP requests and responses when you navigate the application. Henry Dalziel, in How to Hack and Defend your Website in Three Hours, 2015 3.1 The basic process – stepsįirst, map the entire application discover hidden content with the Burp Suite Spider and apply some educated guessing in order to find pages to attack. Our goal with the Burp intercepting proxy feature is to tweak requests so they still follow the rules of HTTP, but can make the application act unexpectedly. Essentially this tool is acting as a proxy, a “man in the middle,” between you and the web application, allowing you to have finer control over the exact traffic you are sending and receiving. In Burp Suite you can then tweak the raw HTTP in various ways before forwarding the request on to the web server. With Burp Suite, however, HTTP requests go from your browser straight to Burp Suite, which intercepts the traffic. Normally HTTP requests go from your browser straight to a web server and then the web server response is sent back to your browser. One of Burp Suite’s main features is its ability to intercept HTTP requests. Take a look around the site on - we will be using this a lot throughout the module.Henry Dalziel, in How to Hack and Defend your Website in Three Hours, 2015 1.15 Using the Burp Suite intercepting proxyīurp Suite is a fully featured web application attack tool: it does almost anything that you could ever want to do when penetration testing a web application. Note: The option is in a dropdown sub-menu. There is one particularly useful option that allows you to intercept and modify the response to your request. Read through the options in the right-click menu. BURP SUITE TRYHACKME WINDOWSNote: Assume you are using Windows or Linux (i.e. Which button would we choose to send an intercepted request to the target in Burp Proxy? If we have uploaded Client-Side TLS certificates in the User options tab, can we override these on a per-project basis (Aye/Nay)? What is the name of the section within the User options “Misc” sub-tab which allows you to change the Burp Suite keybindings? BURP SUITE TRYHACKME UPDATEIn which User options sub-tab can you change the Burp Suite update behaviour? In which Project options sub-tab can you find reference to a “Cookie jar”? Which Burp tool would we use if we wanted to bruteforce a login form? Which Burp Suite feature allows us to intercept requests between ourselves and the target? Which edition of Burp Suite runs on a server and provides constant scanning for target web apps?īurp Suite is frequently used when attacking web applications and _ applications. Which edition of Burp Suite will we be using in this module?
