Burp_wp is an extension of burpsuite used to scan and find vulnerabilities in WordPress plugins and themes using a burpsuite proxy. It was created by Kacper Szurek and can be downloaded from here.

Let’s begin

To run this extension we first need to install Jython. Jython is an implementation of python programming that can run on the Java platform. You can download Jython from here.

Now we download Jython to burpsuite. We go to the python Environment and locate the jar file.

Now we go to the extender, and select extensions tab to add the burp_wp extension.

We click on Add, a pop up will come. We select python as an extension type and give the location at which the burp_wp file is located. We select “show in UI” for standard output and error to get an error if any occur.

As soon as the extension gets installed we get the message in the image below that shows it was installed successfully.

Now we get a new “Burp WP” tab. Burp_WP automatically updates the first time it gets installed. It downloads the list of vulnerable plugins and theme from the database of WPscan.

Now we intercept the request of the website we want to scan for vulnerabilities.

As soon as we forward the request we go to Burp WP tab and we can find all the vulnerable plugins and themes on the website. We will get all vulnerable plugins and themes as we go through the site.

Now we use Metasploit to exploit this vulnerability.

As soon as we run this exploit we get the reverse shell.

In our previous article part1, we had discussed how to perform a brute force attack on any web application server for making unauthorized login into it using some Payload of Burpsuite. In part 2 articles you will learn more about brute force attack with help of remaining BurpSuite payloads that might be helpful in other situation.

Let’s Start!!

Character Substitution

This type of payload allows to configure a list of strings and apply various character substitutions to each item. This type of payload is useful in password guessing attacks and generating common variations on dictionary words.

The UI of this payload allows you to configure a number of character substitutions. For each item, it will generate a number of payloads, which include all permutations of substituted characters according to the defined substitutions.

 For example, the default substitution rules states (which include e > 4 and r > 5), the item “Raj Chandel” will generate the following payloads:

raj chandel

5aj chandel

raj chand4l

5aj chand4l

First, we have intercepted the request of the login page in the DVWA LAB, where we have given a default username and wrong password. Then click on login, the burp suite will capture the request of the login page in the intercept tab.

Send the captured request to the Intruder by clicking on the Action Tab and follow given below step. Now open the Intruder tab then select Positions tab and you can observe the highlighted password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of the window frame.
• Now we will select the fields where we want to attack and i.e. the password filed and click on Add button.
• Choose the Attack type as

• In the given below image, we have selected a password that means we will need one dictionary files for a password.

 Now click on payloads option after selecting payload position. Here we can add a dictionary by clicking on Load option or we can manually add Strings by clicking on the Add option.

Now we have substituted 4>a, 5>s, 9>o as per our requirements to match the password and we have added the input as p445w9rd using the Add option which will substitute the character’s according to the Defined substitution as shown in the image.

Start Attack in the Intruder menu as shown in the image.

Sit back and relax because now the burp suite will do its work, match the password and will give you the correct password. The moment it will find the correct value, it will change the value of length as shown.

 And to confirm the password matched, we will give the matched password in the DVWA LAB login page. We will see a message “Welcome to the password protected area admin” which shows our success in the character substitution payload attack.

Copy Other Payload

This is a type of payload which can copy the value of the current payload to another payload position. It is very useful for attack types that have multiple payload sets such as cluster bomb, pitchfork, and battering ram. This payload type can be useful in various situations, for example:

• Suppose we are using two different parameters and we want to attack at two different fields, therefore we can set different “payload types” at multiple “payload sets” inside burpsuite payload configuration as per our attack type as it allows us to simply use the same dictionary for both payloads that we have set at particular position by giving the position of the payload we want to copy. It will execute the complete payload which is set at a specific position.

First, we have intercepted the request of the login page in the Bwapp LAB, where we have given wrong username and password. Then click on login, the burp suite will capture the request of the login page in the intercept tab.

Send the captured request to the Intruder by clicking on the Action Tab and follow given below step. Now open the Intruder tab then select Positions tab and you can observe the highlighted username and password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of the window frame.
• Now we will select the fields where we want to attack which is the username and password and click on Add button.
• Choose the Attack type as Cluster Bomb.
• In the given below image, we have selected username and password that means we will need two dictionary files i.e. one for username and second for a password.

Now click on payloads option after selecting payload position, here we need to add a dictionary which will use for both payload set. Then select the Payload type as Simple list for Payload Set ‘1’ which will attack at the username field.

Now to attack at the password field we will select Payload type as Copy other payloads for Payload Set ‘2’ because we want to attack the same payload type at payload set 2 which will copy the dictionary given for payload set 1 to attack.

Select Start Attack in the Intruder menu as shown in the image.

Sit back and relax because now the burp suite will do its work, match the username and password which will give you the correct username and password. The moment it will find the correct value, it will change the value of length as shown in the image.

And to confirm the password matched, you can give the matched password in the BWAPP LAB login page.

Username Generator

This type of payload allows you to set up a list of names or email addresses and can produce usernames from given specific schemes.

For example, Let’s take a username “raj chandel” which can give results in up to 115 possible usernames, some combination is as follows :

rajchandel

raj.chandel

chandelraj

chandel.raj

chandel

raj

rajc

etc…

This type of payload is useful to target at a specific user, where you do not know the username or email address scheme of the user which is being used in a specific application.

First, we have intercepted the request of the login page in the Bwapp LAB, where we have given wrong username and password. Then click on login, the burp suite will capture the request of the login page in the intercept tab.

Send the captured request to the Intruder by clicking on the Action Tab and follow given below step. Now open the Intruder tab then select Positions tab and you can observe the highlighted username and password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of the window frame.
• Now we will select the fields where we want to attack which is the username and password and click on Add button.
• Choose the Attack type as Cluster Bomb.
• In the given below image, we have selected username and password that means we will need two dictionary files i.e. one for username and second for the password.

Then select the Payload type as “Username Generator” for Payload Set ‘1’ which will attack at the username field, we have a given input string “raj chandel” by using the Add option as shown in the image, which will use different permutations on that input string given to match the correct username.

Now to attack at the password field we will select Payload type as Simple list for Payload Set ‘2’ for which we have added a dictionary manually created by us by using the Load option.

Select Start Attack in the Intruder menu as shown in the image.

Sit back and relax because now the burp suite will do its work, match the username and password which will give you the correct username and password. The moment it will find the correct value, it will change the value of length as shown in the image.

Dates

This type of payload generates date payloads within a given range and in a specified format. This type of payload is can be used in data mining or brute forcing.

For example, it can be used to guess a user’s birth date, wedding date, anniversary date etc which can be used to brute force the security questions for an application or web applications, or it can use to brute force the password of user’s, where the user uses dates as their password.

The following options are available in this type of payload:

• From – This is said as the first date which will be generated.
• To – This is said as the last date which will be generated.
• Step – This is said as an increase between sequential dates, days, weeks, months or years. It should be a positive value.
• Format – This is said as the format in which dates can be represented. we can select from different predefined date formats, or we can make our own custom date format as per our requirement. Some example of the date format is given below:

E	Mon
EEEE	Monday
D	2
dd	02
M	9
MM	09

Repeat the same to intercept the request of the login page in the Bwapp LAB, where we have given wrong username and password. Then click on login, the burp suite will capture the request of the login page in the intercept tab.

Send the captured request to the Intruder by clicking on the Action Tab and follow given below step. Now open the Intruder tab then select Positions tab and you can observe the highlighted username and password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of the window frame.
• Now we will select the fields where we want to attack which is the username and password and click on Add button.
• Choose the Attack type as Cluster Bomb.
• In the given below image, we have selected username and password that means we will need two dictionary files i.e. one for username and second for the password.

Then select the Payload type as Simple list for Payload Set ‘1’ which will attack at the username field where we have given a dictionary as an input string as shown in given below image.

Now to attack at the password field we will select Payload type as Dates for Payload Set ‘2’ because we are guessing the user might have its birth date or any other date as a password.

After this, we have set the inputs for Payload set ‘2’ in the fields given in the payload options such as FROM, TO, STEP and FORMAT as shown in the image.

Now Select Start Attack in the Intruder menu for brute force attack.

Sit back and relax because now the burp suite will do its work, match the username and password which will give you the correct username and password. The moment it will find the correct value, it will change the value of length as shown in the image.

Burpsuite Decoder can be said as a tool which is used for transforming encoded data into its real form, or for transforming raw data into various encoded and hashed forms. This tool is capable of recognizing several encoding formats using defined techniques. Encoding is the process of putting a sequence of character’s (letters, numbers, punctuation, and symbols) into a specialized format which is used for efficient transmission or storage. Decoding is the opposite process of encoding the conversion of an encoded format back into the original format. Encoding and decoding can be used in data communications, networking, and storage.

Today we are discussing the Decoder Option of ‘Burp Suite’. Burp Suite is a tool which is used for testing Web application security. Its various tools work seamlessly together to support the entire testing process, from initial mapping and analysis of an application’s attack surface, through to finding and exploiting security vulnerabilities. This tool is written in JAVA and is developed by PortSwigger Security.

There are 9 types of decoder format in Burp Suite:

• Plain text
• URL
• HTML
• Base64
• ASCII Hex
• Hex
• Octal
• Binary
• Gzip

URL Encoder & Decoder

When you will explore decoder option in burp suite you will observe two sections left and right. The left section is further divided into two and three sections for encoding and decode option respectively. The right section contains the function tab for encoding and decodes option. And if you will observe given below image you can notice there are two radio buttons for selecting the type of content you want to encode or decode.

Enable the radio button for text option and then we can give any input in the box to be encoded, here we have given Raj chandel as an input as shown in the image. After that click on the Encoded as an option and select URL field from given list as shown in the image. We will get the encoded result in URL format in the second box as shown in the image.

 We can directly decode the Encoded URL Text by clicking on the Decoded as an option and selecting the URL field from the given list of options as shown in the image.  This will decode the encoded URL text into plain text in the third box as shown in the image.

HTML Encoder & Decoder

Repeat the same and give any input in the first box to be encoded, here we have given Raj chandel as an input as shown in the image.

Hello friends!! Today we are discussing about the “Types of Payload in Burp Suite”. Burp Suite is an application which is used for testing Web application security. Its various tools work seamlessly together to support the entire testing process, from initial mapping and analysis of an application’s attack surface, through to finding and exploiting security vulnerabilities. This tool is written in JAVA and is developed by PortSwigger Security. We are going to use the Intruder feature of Burp Suite, it is used to brute force web applications. There are 18 types of payloads in intruder i.e.  

• Simple list
• Runtime File
• Case Modification
• Numbers
• Character substitution
• Custom iterator
• Recursive grep
• Illegal Unicode
• Character blocks
• Dates
• Brute Forcer
• Null Payloads
• Character frober
• Bit Flipper
• Username generator
• ECB block shuffler
• Extension Generated
• Copy other payload

Simple List

This is one of the simple types of payload, as it allows you to configure a short Dictionary of strings which are used as payload.

First, we intercept the request of the login page in the DVWA LAB, where we have given a random username and password. Then click on login, the burp suite will capture the request of the login page.

Send the captured request to the Intruder by clicking on the Action Tab and follow given below step. Now open the Intruder tab then select positions and you can observe the highlighted username and password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of window frame.
• Now we will select the fields where we want to attack which is the username and password and click on Add button.
• Choose the Attack type as Cluster Bomb.
• In the given below image we have selected username and password that means we will need two dictionary files i.e. one for username and second for password.

So now, go to Payloads tab and the select 1 from Payload set (this ‘1’ denotes the first file to be selected). Then click on Load button and select your dictionary file for username.

Now select 2 in the Payload set and again give the dictionary file for the password. Select Start Attack in the Intruder menu as shown in the image.

Now the burp suite will do its work, match the valid combination of username and password and will give you the correct password and username. The moment it will find the correct value, it will change the value of length as shown.

And to confirm the username and password matched, we will give the matched username and password in the DVWA LAB login page. We will see a message “Welcome to the password protected area admin” which shows are success in the simple list payload attack.

Runtime File

This type of payload allows you to configure a file which reads the payload strings at runtime. This type of payload is needed when we require a large list of payloads, to avoid holding the entire list in memory. This payload allows you to configure large list of strings which overcomes the simple list payload type.

First, we have intercepted the request of the login page in the DVWA LAB, where we have given a random username and a random password. Then click on login, the burp suite will capture the request of the login page in the intercept tab.

Send the captured request to the Intruder and follow given below step. Now open the Intruder tab then select positions and you can observe the highlighted password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of window frame.
• Now we will select the fields where we want to attack and i.e. the password filed and click on Add button.
• Choose the Attack type as
• In the given below image we have selected  password that means we will need one dictionary file  for password.

Then select the “Payload type” as Runtime File and then give the path of dictionary in the “payload options” as /usr/share/wordists/rockyou.txt which is the largest dictionary in Kali Linux. Select Start Attack in the Intruder menu.

Now the burp suite will do its work, match the password and will give you the correct password. The moment it will find the correct value, it will change the value of length as shown.

Case Modification

This type of payload allows you to configure a list of strings and apply various case modifications to each item on the list. This is useful in password guessing attacks, for generating case variations on dictionary words.

The following case modification rules can be selected:

• No change – The item is used without being modified.
• To lower case – All letters in the item are converted to lower case.
• To upper case – All letters in the item are converted to upper case.
• To Proper name – The first letter in the item is converted to upper case, and the remaining letters are converted to lower case.
• To Proper Name – The first letter in the item is converted to upper case, and the remaining letters are not changed.

For example, if we select all the modification options, then the item “Raj Chandel” will generate the following payloads:

Raj Chandel

raj chandel

RAJ CHANDEL

Raj chandel

First, we intercept the request of the login page in the DVWA LAB, where we have given a random username and a random password. Then click on login , the burp suite will capture the request of the login page in the intercept tab. Send the captured request to the Intruder by right clicking on the space and selecting Send to Intruder option or simply press ctrl + i.

Now open the Intruder tab then select positions and you can observe the highlighted password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of window frame.
• Now we will select the fields where we want to attack and i.e. the password filed and click on Add button.
• Choose the Attack type as
• In the given below image we have selected  password that means we will need one dictionary file  for password.

Then select the “Payload” type as Case Modification, we have selected the No change and to lower case fields in the “payload options” of the case modification as shown in the image. We have added a default Password dictionary from the Add from list field in the payload options. Select Start Attack in the Intruder menu as shown in the image.

Now the burp suite will do its work, match the password and will give you the correct password. The moment it will find the correct value, it will change the value of length as shown.

Numbers

This type of payload generates numeric payloads within a given range and in a specified format.

The following options are available in this payload:

• Number range:

• Type – the type options describes that the numbers should be generated sequentially or randomly.
• From – If numbers are being generated sequentially, this is the value of the first number that will be generated.
• To – If numbers are being generated sequentially, this value of the last number that will be generated. It is said as the highest possible number that may be randomly generated.
• Step – the step option is used when numbers are being generated sequentially and specifies the increment in the successive numbers.
• How many – This option is available when numbers are being generated randomly, and specifies the number of payloads that will be generated

First, we intercept the request of the login page in the Bwapp Lab, where we have given a random username and a random password. Then click on login, the burp suite will capture the request of the login page.

Send the captured request to the Intruder and follow given below step. Now open the Intruder tab then select positions and you can observe the highlighted password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of window frame.
• Now we will select the fields where we want to attack and i.e. the password filed and click on Add button.
• Choose the Attack type as
• In the given below image we have selected  password that means we will need one dictionary file  for password.

Then select the Payload type as Numbers where we have set the number range from 100 to 150 and we have set the step as 1 as shown in the image, select Start Attack in the Intruder menu.

Now the burp suite will do its work, match the password and will give you the correct password. The moment it will find the correct value, it will change the value of length as shown.

As the password matches with a number which is between the given number range. And to confirm the password matched, we will give the password in the Bwapp LAB login page, which will successfully log us into the Bwapp lab. This shows our success in the attack.

Brute Forcer

This type of payload generates a payload of specified lengths that contain all permutations of list of characters in the given string.

The following options are available:

• Character set – The set of characters to be used in the payloads. Note that the total number of payloads increases exponentially with the size of this set.
• Min length – The length of the shortest payload.

• Max length – The length of the longest payload.

First, we intercept the request of the login page in the Bwapp LAB, where we have given a random username and a random password. Then click on login, the burp suite will capture the request of the login page.

Send the captured request to the Intruder and follow given below step. Now open the Intruder tab then select positions and you can observe the highlighted password and follow the given below step for selecting payload position.

• Press on the Clear button given at right of window frame.
• Now we will select the fields where we want to attack and i.e. the password filed and click on Add button.
• Choose the Attack type as
• In the given below image we have selected  password that means we will need one dictionary file  for password.

Then select the “Payload type” as Brute Forcer where we can give any kind of input into the “character set” as shown in the figure , as we have given 213 and we have set the Min length as 3 and Max length as 3 as shown in the image. We can manually give the Min length and Max length as per your need. Select Start Attack in the Intruder menu as shown in the image.

Now the burp suite will do its work, match the password and will give you the correct password. The moment it will find the correct value, it will change the value of length as shown.

Great!! We have used Top 5 payloads of Burpsuite for login page brute force attack successfully.

Note: In this articles (part-1) we will be performing top 5 payload types and the rest of the payload types will be discussed in the (part-2) of this article.
