![]() ![]() If we click on any of the rows in the table, we get redirected to a page. ![]() The home interface shows us a table of tickets. We can sort our results, one request should stand out as being different.Īfter login, we can see the support home page. Do the same thing for the second payload set and the list of passwords. In the first payload set, go to payload options and choose load then select usernames list. Then change the Attack type to be “Pitchfork” We can avoid a straight bruteforce and instead use a credential stuffing attack.Īctivate the Burp Proxy and try to log in, catching the request in your proxy. This test portal login page has no protective measures in place: It means that we could very easily attack this form using a cluster bomb attack for a bruteforce.īut they give us a list of leaked credentials for Bastion Hosting employees. Payload Encoding: allows us to override the default URL encoding options that are applied automatically to allow for the safe transmission of our payload.Payload Processing: allows us to define rules to applied to each payload in the set before being sent to the target.Payload Options: differ depending on the payload type we select for the current payload set.The second dropdown in this section allows us to select a “payload type”. Payload Sets: allows us to choose which position we want to configure a set for as well as type of payload we would like to use. ![]() “Payloads” sub-tab is split into four sections. In this case, we would use a cluster bomb attack. It uses one payload set per position and iterates(반복하다) through them all at once.Ĭluster bomb allows us to choose multiple payload sets: one per position, up to a maximum of 20 iterates through each payload set individually making sure that every possible combination of payloads is tested.įor example, we have three users and three passwords, but we don’t know how to match them up. It may help to think of Pitchfork as being like having numerous Snipers running simultaneously. For example, this could be a single file containing a wordlist or a range of numbers.īattering ram puts the same payload in every position rather than in each position in turn.Īfter Sniper, Pitchfork is the attack type you are most likely to use. ![]() When conducting a sniper attack, we provide one set of payloads. It is the first and most common attack type. Auto: attempts to select the most likely positions automatically useful if we cleared the default positions and want them back.Add: lets us define new positions by highlighting them in the editor and clicking the button.Resource Pool: not particularly useful to us in Burp Community.Payloads: allows us to select values to insert into each of the positions we defined in the previous sub-tab.Positions: allows us to select an Attack Type, as well as configure where in the request template we wish to insert our payloads.This speed restriction means that many hackers choose to use other tools for brutefocing (like Wfuzz, Ffuf) One problem: to access the full speed of Intruder, we need Burp Professional. For example, by capturing a request containing a login attempt, we could then configure Intruder to swap out the username and password fields for values form a wordlist -> bruteforce the login form. It allows us to take a request and use it as a template to send many more requests with slightly altered values automatically. You should find that you get an alert box from the site indicating a successful XSS attack !Ĭongratulations, you bypassed the filter ! Don't expect it to be quite so easy in real life, but this should hopefully give you an idea of the kind of situation in which Burp Proxy can be useful.Intruder allows us to automate requests, which is very useful when fuzzing or brute forcing. This process is shown in the GIF below :įinally, press the "Forward" button to send the request. After pasting in the payload, we need to select it, then URL encode it with the Ctrl + U shortcut to make it safe to send. With the request captured in the proxy, we can now change the email field to be our very simple payload from above: alert("Succ3ssful XSS"). Submit the form - the request should be intercepted by the proxy. For example: as an email address, and "Test Attack" as a query. Now, enter some legitimate data into the support form. First, make sure that your Burp Proxy is active and that the intercept is on. Let's focus on simply bypassing the filter for now. There are a variety of ways we could disable the script or just prevent it from loading in the first place. You should find that there is a client-side filter in place which prevents you from adding any special characters that aren't allowed in email addresses :įortunately for us, client-side filters are absurdly easy to bypass. Try typing: alert("Succ3ssful XSS"), into the "Contact Email" field. ![]()
