Intruder - Cluster Bomb attack

Purpose: The Cluster Bomb attack type is used for exhaustive testing of all possible combinations of payloads across multiple parameters. This attack type is useful when you need to explore how different inputs interact with each other comprehensively.

How It Works:

  • Combinatorial Explosion: In a Cluster Bomb attack, Burp Suite will try every possible combination of the payloads provided for each parameter. It systematically varies each parameter in every possible way.

  • Thorough Testing: This method can uncover complex interactions between parameters but can generate a large number of requests, so it should be used carefully.

Steps:


1.Capture the Request:

  • Use Burp Suite’s Proxy tab to intercept the login request.

  • For example, the intercepted HTTP POST request might look like this :

                                       POST /example?p1=p1val&p2=p2val HTTP/1.0

                                       Cookie: c=cval

                                       Content-Length: 17

                                        p3=p3val&p4=p4val

2.Set the Positions:

  • Highlight p3 and p4 parameters and set them as variable positions using "Add §".

  • The request will look like this in the Positions tab :


3.Configure Payloads:

In the Payloads tab, set up multiple payload sets:

  • Payload Set 1 for p3 (e.g., 123,234,345).

  • Payload Set 2 for p4 (e.g., a,b,c).



4.Start the Attack:

  • Click "Start Attack" to begin the Cluster Bomb attack.

Result Analysis: Burp Suite will generate requests for every possible combination of p3 and p4. Review the responses to identify if any combination leads to successful authentication or triggers a unique server response.





Conclusion: The Cluster Bomb attack is designed for exhaustive combinatorial testing across multiple parameters. It’s the go-to choice when you need to explore all possible input combinations, especially in complex authentication mechanisms or multi-field forms. While it can generate a large number of requests, its thoroughness ensures that no potential combination is left untested, making it invaluable for uncovering intricate vulnerabilities.

OWASP Top 10 : Understanding Broken Access Control

What is broken access control? Broken access control is a security issue where users can access data or perform actions that they shouldn't be allowed to. This happens when the system fails to properly enforce rules about what users can and cannot do. Types of access controls :  1 . Vertical privilege escalation:  Vertical privilege escalation happens when a normal user gains access to functionalities reserved for higher-privileged users. Example:  A normal user can change the policies of the company.  2. Horizontal privilege escalation:  Horizontal privilege escalation allows a user to switch their access to another user's account, essentially impersonating them. Example:  A normal user can switch their account to admin.  3 . Insecure direct object reference ( IDOR):  IDOR occurs when an application exposes a reference to an internal implementation object, such as a file, directory, or database key. Example:  Suppose...

OWASP Top 10 :Understanding Software and Data Integrity Failures

   What are Software and Data Integrity Failures? Software and Data Integrity Failures refer to issues that compromise the accuracy, consistency, and trustworthiness of software and data. These failures can result from various factors, including malicious attacks, software bugs, or misconfigurations. Key Types of Software and Data Integrity Failures: 1. Input Validation Failures : Occur when the software does not properly validate input data. Examples : Buffer overflows, SQL injection, and cross-site scripting (XSS). 2. Authentication and Authorization Failures : Occur when there are weaknesses in verifying user identities or controlling user permissions. Examples : Broken authentication mechanisms, and improper access controls. 3. Cryptographic Failures : Involve weaknesses or misconfigurations in cryptographic mechanisms. Examples : Use of weak encryption algorithms, and improper key management. 4. Configuration and Deployment Failures : Arise from incorrect software or...

Intruder - Sniper Attack

Purpose:  The Sniper attack type is designed to test one input position at a time, allowing you to see how a single variable affects the outcome of a request. This is particularly useful for brute-force attacks on parameters like usernames, passwords, session tokens, etc. How It Works: Single Position Testing:  In a Sniper attack, you identify a single position in your request where the payloads will be inserted one by one. Each request only varies by this one position. Payload Iteration:  Burp Suite will go through the list of payloads you provide and substitute them at the designated position, sending a new HTTP request for each payload. Steps: 1.Capture the Request: Use Burp Suite’s Proxy tab to intercept the login request. For example, the intercepted HTTP POST request might look like this :                                       ...
