Burp suite professional edition v2020.8.1 x64 full activated + all addons

Copy other payload

This payload type copies the value of the current payload at another payload position. It can be used with that have multiple payload sets (cluster bomb and battering ram). You can also define payload processing rules so that you can systematically derive the current payload from the value of a payload at another position, rather than just copying its literal value.

This payload type can be useful in various situations, for example:

  • Two different parameters must always have the same value in order to hit a target code path (for example, fields for new and confirm passwords), and you want to use the cluster bomb attack type to manipulate other parameters at the same time.
  • One parameter value in the request contains a checksum of another parameter value, which is normally computed by a client-side script based on user input.

Smart decoding

On any panel within Decoder, you can click the «Smart Decode» button. Burp will then attempt to intelligently decode the contents of that panel by looking for data that appears to be encoded in recognizable formats such as URL-encoding or HTML-encoding. This action is performed recursively, continuing until no further recognizable data formats are detected. This option can be a useful first step when you have identified some opaque data, and want to take a quick look to see if it can be easily decoded into a more recognizable form. The decoding that is applied to each part of the data is indicated using the usual colorization.

Because Burp Decoder makes a «best guess» attempt to recognize some common encoding formats, it will sometimes make mistakes. When this occurs, you can easily see all of the stages involved in the decoding, and the transformation that was applied at each position. You can then manually fix any incorrect transformations using the , and continue the decoding manually or smartly from this point.

The basics of using Burp

For help with installing and launching Burp, starting projects, and configuring display settings, please see the help on Getting started with Burp Suite.

To use Burp for penetration testing, you can either:

  • Use Burp’s embedded browser, which requires no additional configuration. Go to the «Proxy» > «Intercept» tab and click «Open Browser». A new browser session will open in which all traffic is proxied through Burp automatically. You can even use this to test over HTTPS without the need to install Burp’s CA certificate.
  • Use an external browser of your choice. For various reasons, you might not want to use Burp’s embedded browser. In this case, you need to perform some additional steps to configure your browser to work with Burp, and install Burp’s CA certificate in your browser.

Once you have Burp running and have either opened the embedded browser or configured your own external browser, go to the Proxy Intercept tab, and ensure that interception is turned on (if the button says «Intercept is off» then click it to toggle the interception status). Then go to your browser and visit any URL.

Each HTTP request made by your browser is displayed in the Intercept tab. You can view each message, and edit it if required. You then click the «Forward» button to send the request on to the destination web server. If at any time there are intercepted messages pending, you will need to forward all of these in order for your browser to complete loading the pages it is waiting for. You can toggle the «Intercept is on / off» button in order to browse normally without any interception, if you require. For more help, see Getting started with Burp Proxy.

As you browse an application via Burp, the Proxy history keeps a record of all requests and responses. In the Proxy, go to the History tab and review the series of requests you have made. Select an item in the table and view the full messages in the Request and Response tabs.

Also, as you browse, Burp by default builds up a site map of the target application. Go to the Target tab, and the Site Map sub-tab, to view this. The site map contains all of the URLs you have visited in your browser, and also all of the content that Burp has inferred from responses to your requests (e.g. by parsing links from HTML responses). Items that have been requested are shown in black, and other items are shown in gray. You can expand branches in the tree, select individual items, and view the full requests and responses (where available). For more help, see Using the Target tool. You can control which content gets added to the site map as you browse, by configuring a suitable live scanning task.

At the core of Burp’s penetration testing workflow is the ability to pass HTTP requests between the Burp tools, to carry out particular tasks. You can send messages from the Proxy intercept tab, the Proxy history, the site map, and indeed anywhere else in Burp that you see HTTP messages. To do this, select one or more messages, and use the context menu to send the request to another tool.

The Burp tools you will use for particular tasks are as follows:

  • Scanner — This is used to automatically scan websites for content and security vulnerabilities.
  • Intruder — This allows you to perform customized automated attacks, to carry out all kinds of testing tasks.
  • Repeater — This is used to manually modify and reissue individual HTTP requests over and over.
  • Collaborator client — This is used to generate Burp Collaborator payloads and monitor for resulting out-of-band interactions.
  • Clickbandit — This is used to generate clickjacking exploits against vulnerable applications.
  • Sequencer — This is used to analyze the quality of randomness in an application’s session tokens.
  • Decoder — This lets you transform bits of application data using common encoding and decoding schemes.
  • Comparer — This is used to perform a visual comparison of bits of application data to find interesting differences.

You can combine Burp’s different tools in numerous ways, to perform testing tasks ranging from very simple to highly advanced and specialized.

Interface & Options

Like any other GUI/Windows tool, burpsuite contains a standard menu bar, 2 rows of tabs & different set of panels as seen below.

Burpsuite Window

The above figure shows the options & details about the target. In the above figure there are mainly 4 sections. They are described against the corresponding numbers as follows:

  1. Tool & Options selector Tabs – Select between Various tools & settings of burpsuite
  2. Sitemap View – Displays the sitemap once spider has started
  3. Requests Queue – Displays the requests being made
  4. Request/Response Details – The HTTP requests made & the responses from the servers.

Timeouts

These settings specify the timeouts to be used for various network tasks. You can specify the following timeouts:

  • Normal — This setting is used for most network communications, and determines how long Burp will wait before abandoning a request and record that a timeout has occurred.
  • Open-ended responses — This setting is only used where a response is being processed which does not contain a Content-Length or Transfer-Encoding HTTP header. In this situation, Burp waits for the specified interval before determining that the transmission has been completed.
  • Domain name resolution — This setting determines how often Burp will re-perform successful domain name look-ups. This should be set to a suitably low value if target host addresses are frequently changing.
  • Failed domain name resolution — This setting determines how often Burp will reattempt unsuccessful domain name look-ups.

Values are in seconds. If an option is left blank, then Burp will never time out that function.

Cookie jar

Burp maintains a cookie jar that stores all of the cookies issued by web sites you visit. The cookie jar is shared between all of Burp’s tools.

You can configure which tools the cookie jar should monitor in order to update cookies. By default, the cookie jar is updated based on traffic from the Proxy and Spider tools. Burp monitors responses received by the configured tools, and updates the cookie jar with any new cookies that are set. In the case of the Proxy, incoming requests from the browser are also inspected. This is useful where an application has previously set a persistent cookie which is present in your browser, and which is required for proper handling of your session. Having Burp update its cookie jar based on requests through the Proxy means that all the necessary cookies will be added to the cookie jar even if the application does not update the value of this cookie during your current visit.

You can also view the contents of the cookie jar and edit cookies manually, using the «Open cookie jar» button.

The cookie jar can be used by and to automatically update outgoing requests with cookies from the cookie jar.

The cookie jar honors the domain and path scope of cookies, in a way that mimics Internet Explorer’s interpretation of cookie handling specifications.

Features of Burp Suite Professional

Below are some noticeable features which you’ll experience after Burp Suite Professional download free.

  • Powerful page crawler
  • Advanced web page scanner with the ability to automate the process of detecting security weaknesses
  • Suitable tools for testing custom and planned attacks for specific purposes
  • Conduct bat-force attacks to test the permeability of critical parts of the site
  • Repeater tool to repeat a request many times
  • A tool for testing randy site pages
  • Ability to store work and postpone work to another time
  • High flexibility of the program (the ability to write proprietary plugins, perform custom tests based on your request)

Upstream proxy servers

These settings control whether Burp will send outgoing requests to an upstream proxy server, or directly to the destination web server.

You can define multiple rules, specifying different proxy settings for different destination hosts, or groups of hosts. Rules are applied in sequence, and the first rule that matches the destination web server will be used. If no rule is matched, Burp defaults to direct, non-proxied connections.

You can use wildcards in the destination host specification (* matches zero or more characters, and ? matches any character except a dot). To send all traffic to a single proxy server, create a rule with * as the destination host. Leave the proxy host blank to connect directly to the specified host.

For each upstream proxy you configure, you can specify an authentication type and credentials if required. Supported authentication types are: basic, NTLMv1, and NTLMv2. The domain and hostname fields are only used for NTLM authentication.

ECB block shuffler

This payload type can be used to shuffle blocks of ciphertext in ECB-encrypted data, so as to meaningfully modify the decrypted cleartext and potentially interfere with application logic.

Because ECB ciphers encrypt each block of plaintext independently of others, identical blocks of plaintext encrypt into identical blocks of ciphertext (provided the same key is used), and vice versa. Hence, it is possible to shuffle blocks within a large piece of ciphertext with the effect of shuffling the corresponding blocks of decrypted plaintext. In some data (such as a structured session token with fields for username, user ID, role, and a timestamp) it may be possible to meaningfully alter the content of the decrypted data so as to interfere with application processing, and carry out unauthorized actions.

The following options are available:

  • Encrypted data to shuffle — This option lets you specify whether to operate on the base value of the payload position, or on another string.
  • Format of original data — This option lets you specify whether the generator should operate on the literal value of the original data, or should treat it as ASCII hex (see the payload type for more details).
  • Block size — This is the size in bytes of the encrypted blocks. In most cases, the blocks are 8 or 16 bytes in size. If you are unsure, you should run the attack multiple times using each block size that might be in use.
  • Additional encrypted strings — This list lets you optionally supply a list of encrypted strings that use the same cipher and key, to provide additional blocks for shuffling into the encrypted data. Because successful attacks of this type often require a considerable degree of luck, in terms of finding a block with a suitable plaintext value that can be shuffled in to the correct point in the structure, the odds of success are frequently improved by obtaining a large sample of strings that have been encrypted by the same application function. For example, if you are attacking a session token using this payload type, it would be beneficial to harvest a large number of other session tokens from the application, to provide additional blocks of ciphertext.

System Requirements For Burp Suite Professional

Before you start Burp Suite Professional free download, make sure your PC meets minimum system requirements.

    • Operating System: Windows 7/8/8.1/10
    • Memory (RAM): 1 GB of RAM required.
    • Hard Disk Space: 600 MB of free space required.
    • Processor: Intel Pentium 4 or later.

Additional Requirement Notes:

Burp requires a minimum of 4Gb of memory. If you are running large amounts of work, or testing large or complex applications, you may need more memory than this. If you are unsure whether your computer is suitable, you should first test the free edition of Burp Suite on your computer to ensure that it works correctly.

Transformations

Different transformations can be applied to different parts of the data. The following decode and encode operations are available:

  • URL
  • HTML
  • Base64
  • ASCII hex
  • Hex
  • Octal
  • Binary
  • GZIP

Additionally, various common hash functions are available, dependent upon the capabilities of your Java platform.

When a part of the data has a transformation applied, the following things happen:

  • The part of the data to be transformed is colorized accordingly. (View the to see the colors used.)
  • A new editor is opened showing the results of all the applied transformations. Any parts of the data that have not been transformed are copied into the new panel in their raw form.

The new editor enables you to work recursively, applying multiple layers of transformations to the same data, to unpack or apply complex encoding schemes. Further, you can edit the transformed data in any of the editor panels, not only the top panel. So, for example, you can take a complex data structure, perform URL and HTML decoding on it, edit the decoded data, and then reapply the HTML and URL encoding (in reverse order), to generate modified but validly formatted data to use in an attack.

Recon and analysis

The Proxy tool lies at the heart of Burp’s workflow. It lets you use your browser to navigate the application, while Burp captures all relevant information and lets you easily initiate further actions. In a typical test, the recon and analysis phase involves the tasks described below.

Manually map the application

Using your browser working through Burp Proxy, by following links, submitting forms, and stepping through multi-step processes. This process will populate the Proxy and Target site map with all of the content requested, and (via live scanning) will add to the site map any further content that can be inferred from application responses (via links, forms, etc.). You should then (shown in gray in the site map), and request these using your browser.

Perform automated mapping where necessary

You can optionally use Burp to automate the mapping process in various ways. You can:

  • Carry out automated scanning to crawl the application’s content.
  • Use the content discovery function to find further content that is not linked from visible content that you can browse to or spider.
  • Perform using Burp Intruder, to cycle through lists of common files and directories, and identify hits.

Note that before performing any automated actions, it may be necessary to update various aspects of Burp’s , such as and session handling.

Analyze the application’s attack surface

The process of mapping the application populates the Proxy and Target site map with all the information that Burp has captured about the application. Both of these repositories contain features to the information they contain, and assess the attack surface that the application exposes. Further, you can use Burp’s Target Analyzer to report the extent of the attack surface and the different types of URLs the application uses.

Launching scans

Scans can be launched in a variety of ways:

  • Scan from specific URLs. This performs a scan by crawling the content within one or more provided URLs, and optionally auditing the crawled content. To do this, go to the Burp Dashboard, and click the «New scan» button. This will open the scan launcher which lets you configure details of the scan.
  • Scan selected items. This lets you perform an audit-only scan (no crawling) of specific HTTP requests. To do this, select one or more requests anywhere within Burp, and select «Scan» from the context menu. This will open the scan launcher which lets you configure details of the scan.
  • Live scanning. You can use live scans to automatically scan requests that are processed by other Burp tools, such as the Proxy or Repeater tools. You can configure precisely which requests are processed, and whether they should be scanned to identify content or audit for vulnerabilities. To do this, go to the Burp Dashboard, and click the «New live task» button. This will open the live scan launcher which lets you configure details of the task.
  • Instant scanning. You can also launch instant active or passive scans from the context menu. This means you can quickly check for vulnerabilities without having to open the scan launcher. You can access these options by right-clicking on a request. Alternatively, you can configure hotkeys for triggering instant scans.

Configuring scans

You can launch multiple scans in parallel, and each scan has its own configuration options that determine exactly how the scan is carried out. There are two key areas of configuration:

  • Crawl options. These options control behavior like maximum link depth, how the crawler optimizes for speed versus coverage, and limits on the extent of the crawl. Read more
  • Audit options. These options control behavior like the handling of insertion points and what detection methods are employed. These options are very important in controlling what type of audit activity will be performed, from a lightweight purely passive analysis through to a heavyweight invasive scan. Read more

Lab 1 : Spidering a website

Spidering is a major part of recon while performing Web security tests. It helps the pentester to identify the scope & archetecture of the web-application.As described earlier, burpsuite has it’s own spider called the burp spider which can crawl into a website.

Scenario: Attacker – Kali Linux VM, IP = 192.168.0.105

Target – OWASP Broken Web Application VM, IP = 192.168.0.160

Step 1 : Setup Proxy

First, start burpsuite and check details under the proxy tab in Options sub-tab. Ensure IP is localhost IP & port is 8080.

Proxy Options & Information

Also, ensure that Intercept is ON in the Intercept Sub-Tab

Turning ON intercept

Then on IceWeasel/Firefox, Goto Options > Preferences > Network > Connection Settings.

Choose Manual Proxy Configuration

Setting Proxy in IceWeasel

If you want, you can try installing proxy add-ons. Here is one such.

Install the proxy selector from addons page and goto preferences

Setting Up Addons

Goto Manage Proxies & add a new proxy filling out the relevant information. It’s simple.

Configuring Addon Proxy

Click the Proxy Selector button at the Top right & select the Proxy you just created.

Setting Up Addons

Step 2 : Getting Content into Burpsuite

After you have setup the proxy, goto the target normally by entering the URL in the address bar. You can notice that the page will not be loading up. This is because burpsuite is intercepting the connection.

Page Loading

Meanwhile, in burpsuite, you can see the request details. Click forward to forward the connection. Then you can see that the page has loaded up in the browser.

burp interceptingPage Loaded

Comming back to burpsuite, you can see that all sections are populated.

Sitemap, Requests & Request/Response Details

Step 3 : Scope Selection & Starting Spider

Now narrow down the target as you want. Here the target/mutillidae is selected. Right click the mutillidae from the sitemap & select Spider from Here option

Selecting the target

After the spider starts, You get a prompt as shown in the following figure. It’s a login form. If you know the details, fill in as needed & thus the spider wil be able to crawl from the inside also. You can skip this step by pressing the Ignore Form button.

Submitting a Login form

Step 4 : Manipulating Details

Now you can see as the spider runs, the tree inside of the mutillidae branch gets populated. Also, the requests made are shown in the queue and the details are shown in the Request tab.

Finally, check if the spider is finished by viewing the Spider tab.

Spider Status

These are the very basics & starting point of a web security test. Spidering is an important part of the recon during the test and by clearly executing this, we can understand about the architecture of the target site.  In upcomming tutorials, we will extend this to other tools in the Burpsuite set of tools.

Integration with Burp tools

Burp’s session handling features interact with Burp’s other functionality in some important ways:

  • There is a default session handling rule that updates requests made by the Scanner with cookies from Burp’s cookie jar, except when the Scanner is managing its own sessions (during crawling and crawl-driven auditing). If this is not the behavior you require, you should disable the default session handling rule before performing any scanning.
  • In cases where session handling rules modify a request before it is made (for example, to update a cookie or other parameter), some of Burp’s tools will show the final, updated request, for purposes of clarity. This applies to the Intruder, Repeater and Spider tools. Requests that are shown within reported Scanner issues continue to show the original request, to facilitate clear comparison with the base request, where necessary. To observe the final request for a scan issue, as modified by the session handler, you can send the request to Burp Repeater and issue it there (provided you have the same session handling rules enabled for Repeater as for Scanner).
  • When the Scanner or Intruder makes a request that manipulates a cookie or parameter that is affected by a session handling action, the action is not applied to that request, to avoid interfering with the test that is being performed. For example, if you are using Intruder to fuzz all the parameters in a request, and you have configured a session handing rule to update the cookie in that request, then the cookie will be updated when Intruder is fuzzing other parameters. When Intruder is fuzzing the cookie itself, Burp will send the Intruder payload string as the value, and the session handling rule will not update the cookie as is done normally.

Session handling challenges

When performing any kind of testing of web applications, you may encounter challenges relating to session handling and state. For example:

  • The application may terminate the session being used for testing, either defensively or for other reasons, so that subsequent requests are ineffective until the session is restored.
  • Some functions may use changing tokens that must be supplied with each request (for example, to hinder request forgery attacks).
  • Some functions may require a series of other requests to be made before the request being tested, to get the application into a suitable state for it to accept the request being tested.

These challenges may arise when carrying out automated testing tasks, such as fuzzing or scanning, and may also arise when you are testing manually.

Burp’s session handling functionality contains a range of features to help in all of these situations, letting you continue your manual and automated testing while Burp takes care of the problems for you in the background.

Burp Suite Professional Overview


Burp Suite is a great tool for testing websites. There are a few tools available to test all the tests needed to measure the permeability of a website. The program claims to be capable of integrating all types of tests from basic analyzes to finding weaknesses and expulsions in an integrated way. This feature does not allow you to test individual cases for individual programs. Most of the tests for this program are done automatically and will be shown to you with the minimum amount of information.

BurpSuite prioritizes their risk profile by reviewing their weaknesses and provides them with appropriate suggestions. With a wide range of features, this tool also has a great look. All parts of the program are provided with understandable phrases and explanations that leave no room for doubt. However, everywhere you have questions, you can get enough information by visiting the program guide. The program is well-versed in the Bruce Force Penetration Test and can do a wide variety of experiments. We recommend that you use this app if you are in network security or if you plan to measure the security of your website because it is a combination of capability, beauty and simplicity.

Macros

A macro is a predefined sequence of one or more requests. You can use macros within to perform various tasks. Typical use cases for macros include:

  • Fetching a page of the application (such as the user’s home page) to check that the current session is still valid.
  • Performing a login to obtain a new valid session.
  • Obtaining a token or nonce to use as a parameter in another request.
  • When scanning or fuzzing a request in a multi-step process, performing the necessary preceding requests, to get the application into a state where the targeted request will be accepted.
  • In a multi-step process, after the «attack» request, completing the remaining steps of the process, to confirm the action being performed, or obtain the result or error message from the conclusion of that process.

As well as the basic sequence of requests, each macro includes some important configuration about how cookies and parameters in the sequence should be handled, and any interdependencies between items.

For more details of configuring macros, see the Macro editor help.

Session handling rules

Burp lets you define a list of session handling rules, giving you very fine-grained control over how Burp deals with an application’s session handling mechanism and related functionality.

Each rule comprises a scope (what the rule applies to) and actions (what the rule does). For every outgoing request that Burp makes, it determines which of the defined rules are in-scope for the request, and performs all of those rules’ actions in order (unless a condition-checking action determines that no further actions should be applied to the request).

The scope for each rule can be defined based on any or all of the following features of the request being processed:

  • The Burp that is making the request.
  • The of the request.
  • The names of within the request.

Each rule can perform one or more , such as:

  • Updating cookies from Burp’s cookie jar.
  • Validating the current session.
  • Running a macro (predefined sequence of requests).

By creating multiple rules with different scopes and actions, you can define a hierarchy of behavior that Burp will apply to different applications and functions. For example, on a particular test you could define the following rules:

  • For all requests, add cookies from Burp’s cookie jar.
  • For requests to a specific domain, validate that the current session with that application is still active, and if not, run a macro to log back in to the application, and update the cookie jar with the resulting session token.
  • For requests to a specific URL containing the parameter, first run a macro to obtain a valid value, and use this when making the request.

For more details of configuring session handling rules, see the Session handling rule editor help.

Session handling tracer

The configuration needed to apply Burp’s session handling functionality to the features of real-world applications is often complex, and mistakes are easily made. You can use the session handling tracer to assist with troubleshooting your session handling configuration.

The tracer shows a listing of every request that has been handled by the session handling functionality (that is, where at least one session rule has been applied). For each handled request, the tracer shows the sequence of rules and actions that were carried out, and the changes made to the current request at each step in the sequence.

Note that the session handling tracer imposes a processing and storage overhead on all affected HTTP requests. You should only use the tracer when troubleshooting issues with session handling rules, and should not leave it running generally.

Tool configuration

Burp contains a wealth of configuration options, which it is often necessary to use at different stages of your testing, to ensure that Burp works with your target application in the way you require. For example:

  • Display — You can configure the and used to display HTTP messages, and also the in Burp’s own UI.
  • Target scope — The target scope configuration tells Burp the items that you are currently interested in and willing to attack. You should configure this early in your testing, as it can control which items are displayed in the Proxy and Target , which messages are in the Proxy, and which items may be scanned.
  • Platform authentication — If the application server employs any platform level (HTTP) authentication, you configure Burp to handle the automatically.
  • Session handling — Many applications contain features that can hinder automated or manual testing, such as reactive session termination, use of per-request tokens, and stateful multi-stage processes. You can configure Burp to handle most of these situations seamlessly, using a combination of and .
  • Task scheduling — You can configure Burp to schedule tasks at given times or intervals, to allow you to work within specified testing windows.
