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...

Intruder - Battering Ram Attack

Purpose: The Battering Ram attack type is used when you need to insert the same payload into multiple positions within the same request. This can be useful in scenarios where multiple fields might share the same value or where you want to test how the application handles identical inputs across different parameters. How It Works: Multiple Position Synchronization: In a Battering Ram attack, the same payload is simultaneously inserted into all the designated positions within the request. Synchronized Input Testing: This type of attack is beneficial for testing inputs that are expected to be the same or related across different fields. 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 : ...

Overview Of All Tabs Burp Suite

Burp Suite is a powerful tool used in web application security testing. It has multiple tabs, each designed for specific tasks in the process of testing and analyzing web applications. Here's an overview of the main tabs in Burp Suite: 1. Dashboard tab: Purpose : The Dashboard tab provides a comprehensive overview of all active tasks, scans, and events, allowing you to monitor the progress and status of your security testing efforts in real time. Key Features : Task Management : Displays a list of all active, scheduled, and completed tasks, such as vulnerability scans, intruder attacks, or other automated processes. Event Log : Keeps a detailed log of events, such as the start and end of tasks, errors, and significant actions taken during your testing sessions. Live Status : Shows real-time progress of ongoing tasks, including scan coverage, number of issues found, and other relevant metrics. Scan Queue : Manages and prioritizes multiple scanning tasks, allowing you to queue them ...
