How to configure Burp Suite with Firefox. To access the embedded browser, go to the 'Proxy' 'Intercept' tab, and click 'Open Browser'. The process for installing Burp's CA certificate varies depending on which browser you are using. Please select the appropriate link below for detailed information about installing the certificate on. Burp Suite operates as a web proxy server between your browser and target applications and lets you intercept, inspect, and modify the raw traffic passing in both directions. Burp is designed to be used alongside your browser. Burp functions as an HTTP proxy server and all HTTP/S traffic from your browser passing through Burp. Burp Suite Settings and Browser Configuration - Burp suite is a Web Hacking Penetration Tool. It is an integrated platform for performing security testing of web applications. With chrome configure burp suite how to configure burp suite with firefox burp suite chrome certificate how to configure burp suite with firefox in kali linux how to.

In Burp, go to the 'Proxy' tab and open the 'Intercept' sub-tab. Both of these tabs should be highlighted. On the 'Intercept' tab, you should see the intercepted HTTP request in the main panel. Notice the button that says 'Intercept is on'.

Introduction:

Burp suite is an intercepting proxy that can intercept requests from client side & responses from the server side. The ability to intercept allows hackers to manipulate requests/responses to look for & exploit vulnerabilities. It is mainly used by experienced security engineers & pen testers as it presents a single interface with various integrated toolsets.

Burp Suite has multiple capabilities. The professional & Enterprise version of the tool have scanner feature that scans a target web application / API to discover vulnerabilities. This is possible only if we are able to intercept the requests first.

Burp Suite Professional also as an extender tab where in we can add a set of extensions that can look for additional security violations or work slightly in a different way to discover some default vulnerability checks applied by the scanner

Getting Burp Suite :

Burp Suite is available in following types

Burp Suite Community

Burp Suite Professional

Burp Suite Enterprise

The community version is available for everyone & free to use. It can be downloaded from the portswigger official website. The Professional & Enterprise versions are available as a commercial use. If you are someone that didn’t try this tool & if your organization hasn’t requested for a trial license before then you can use this chance to request for trial version valid for 30 days with full features(note: this option is available while publishing this content, may change in future). Assume we are going to request for trial license for valid reasons to make best use of it.

Burp Suite Configuration Firefox

Installing Burp Suite:

Burp Suite can be run on any operating system (OS) if the OS supports the specific java version installed as it is a java application & available in a JAR format to launch & use the tool.

We are using Burp Suite Pro v2020.2.1 & it requires minimum Java version 8 to install / run the tool.

Configuring Burp Suite:

Before we can use Burp suite, we need to configure it with our client so we can intercept requests/responses. Follow the sections 1,2,3 below to configure

Section 1, Configure browser with Burp Suite

open Burp —> proxy —> Options—> Add Proxy Listener

By Default burp suite runs on 8080 port. so the default proxy listener is localhost:8080. We need to set this proxy listener in our browser to intercept requests/responses.

open Firefox —> Preferences —> Network settings —> set Manual proxy configuration to localhost:8080

Section 2, Install Burp root CA certificate

This is required to intercept encrypted traffic.

open Burp —> proxy —> Options—> click import/export CA certificate to export the certificate

After the certificate is exported, now open Firefox —> Preferences —> certificates —> Import certificate

Section 3, set Upstream proxy server

In some corporate networks, there is a proxy configured to connect to internet. To access external sites hosted outside the corporate network or to connect to internet we are required to set the upstream proxy.

to set this, open Burp —> User Options —> Add Upstream Proxy Servers

Burp Suite Integrated toolsets:

Repeater : It is used to replay the base request with altered/manipulated request parameters & observe the response from server. This feature helps to confirm the existence of a vulnerability as we can replay & observe responses. It becomes a bit easier to check for access control violations with the use of repeater as we will need to alter specific id’s or resources of a user with another user

Intruder : It is used to target specific request parameters with a list of custom payloads & observe the responses for each of the payloads/manipulated requests.

Sequencer : It is used to check for the strength of the tokens such as session cookies , forgot password tokens or user invited tokens etc.,

Decoder : It is used to decode/encode data in to specific formats such as base64, url encode/decode, hex format etc.,

Comparer : It is used to compare two requests or responses to check for any variations.

Burp HotKeys:

we can use key board short cuts to traverse between various sections/tabs of the tools. It can configured from user options —> Misc —> Hot keys

on MacOs, some hot key examples are

command+shift+R —> Repeater tab

Burpsuite

command+shift+T —> Target tab

Burp

command+shift+I —> Intruder tab

Spidering / Crawling :

Crawl is an interesting feature as the tool automatically crawls a target website to discover all traversable links, parameters, resources etc.,It is recommended to set the scope of the spider to ensure only target site is crawled & consider setting specific crawl parameters to ensure the scanner isn’t overloaded with unrealistic crawl settings

for example : Unique location discovered : should be a realistic/appropriate value

Passive scanning:

During this phase the scanner doesn’t actual send any malicious requests on its own to the server, it simply observes all intercepted requests / responses & reports if there are any missing security header settings , secure cookie settings , sensitive tokens in GET request , other passive checks etc.,

some of the passive checks are applied as soon as the requests/responses are intercepted. To do a passive scan to cover all passive rules, we need to add the target site to scope & right click the target site to choose, passively scan this host

Active Scanning:

Burp Suite Configuration Firefox Chrome

During this phase the scanner sends malicious requests on its own to the server from the initial or baseline intercepted requests , observes the responses from the server for each of this malicious requests to identify & report vulnerabilities such as SQL Injection, XSS , etc.,

To do an active scan, we need to add the target site to scope & right click the target site to choose, Actively scan this host

Adding Extensions:

Burp suite has an menu option, Extender. Most of the extensions are either developed in python, java or Ruby. For this reason, we need to set the environment settings under Options section of Extender Tab. Generally to set the java environment settings, we need to point to the location of the java JRE bin installed path, like wise for python, we need to set the location of Jythonstandalone.jar file present in our machine.

After the environment settings are completed, we can add extensions in two different ways. The easiest way to add an extension is go to BApp Store under the Extender tab & choose a extension from the list that you may want to add & use as per your need. Just click install from the right pane to install the extension. To successfully install a extension, the relevant environment setting is a must. Some extensions are available for community version but some are available for only professional version of the tool.

Burp Suite BAppStore has a limited set of extensions, there are lot more extensions available from other resources, such as github, we recommend that you use only extensions that are required & to avoid overloads. Some extensions will fall part of the default scanner to look for vulnerabilities but some will need to be used in a manual way.

Disable Extensions :

There are couple of ways to disable extensions, to disable all extensions, we can tick the checkbox “Disable extensions” while launching burp.

To disable a specific extension, go to Extender tab —> Extensions —> uncheck a specific extension that you do not wish to use.

Engagement Tools — Search / Find Comments / Find Scripts / Find References / Analyse Target / Simulate Manual Testing

Search : Used to search for specific strings or to search & look for sensitive information disclosure such as API keys, credentials etc.,

Find Comments : When used shows all comments left over by developers in target site resources

Find References: When used shows the reference of the target site in various places of the intercepted requests / responses

Analyze Target: when used displays, number of dynamic urls, static urls,parameters, unique parameter names

Simulate Manual Testing: Let’s you take a break while the tool automatically sends requests to the target site to avoid session timeouts.

What is Burpsuite

Burp Suite, a framework of web application pentesting tools, is widely regarded as the tool to use when performing web app testing. BurpSuite acts as a proxy between your browser and sending it through the internet – It allows the BurpSuite Application to read and change/send on HTTPS data.

The suite can run under windows and linux.

Install: https://portswigger.net/burp/communitydownload

Burp Suite requires Java JRE in order to run. Download and install Java here:
https://www.java.com/en/download/

After install we need to do some configurations.

Configuring with Firefox

Start Burpsuite. Accept al defaults

Start firefox

let’s add an extension to our web browser to allow up to easily route or traffic through it. We use FoxyProxy Standard https://addons.mozilla.org/en-US/firefox/addon/foxyproxy-standard/

Next, click on FoxyProxy among your extensions in the upper right corner

After that, click on ‘Options’.

click ‘Add’ in the top left to add Burpsuite as a proxy to FoxyProxy

Enter in the following settings and then click ‘Save’

  • Proxy IP = 127.0.0.1
  • Port = 8080
  • Title = Burpsuite

Now we need to make sure the traffic is going to burpsuite. Click on the FoxyProxy extension icon again and select ‘Burp’.

To test you can go to Go to http://localhost:8080 or http://127.0.0.1:8080

Now we need to add the CA certificate

Click on the CA Certificate

Save the certificate

Now that we’ve downloaded the CA Certificate, move over to the settings menu in Firefox. Search for ‘Certificates’ in the search bar.

Click on ‘View Certificates’

Next, in the Authorities tab click on ‘Import’

Select trust this CA to identify web sites and select trust this ca to identify email users

Select ‘OK’ once you’ve done this. Congrats, we’ve now installed the Burp Suite.
