Exploring Trishul: A Burp Suite Extension for Automated Vulnerability Detection

Burp Suite, a popular cybersecurity tool, has long been the go-to choice for professionals in the field. It's renowned for its robust set of features, flexibility, and an extensive community of users and developers. One of the many strengths of Burp Suite is its extensibility, allowing security professionals to enhance its capabilities by adding custom extensions. One such extension that has gained attention is Trishul. Trishul is a Burp Suite extension designed to automate vulnerability detection, making the testing process faster and more efficient.

In this blog post, we'll delve into what Trishul is, how to install it, and how it can streamline the vulnerability detection process.

What is Trishul?

Trishul is an automated vulnerability finding Burp Suite extension, designed to streamline security testing by automating the detection of various vulnerabilities in web applications. The extension is written in Jython, which is an implementation of Python that runs on the Java Virtual Machine. This allows it to seamlessly integrate with Burp Suite's extender capabilities.

Trishul's primary goal is to save time for security professionals and penetration testers by automating the process of identifying common vulnerabilities, including:

1. Cross-Site Scripting (XSS): Trishul scans for XSS vulnerabilities, which can allow attackers to inject malicious scripts into web pages viewed by other users.
2. SQL Injections: It identifies SQL injection vulnerabilities, which can lead to unauthorized access to a database.
3. Server-Side Template Injections: Trishul also helps find server-side template injection vulnerabilities, a critical issue where an attacker can execute arbitrary code on the server.

How to Install Trishul

Installing Trishul is a straightforward process. Follow these steps:

1. Download Burp Suite: Visit the official Burp Suite download page at http://portswigger.net/burp/download.html and download the version suitable for your system (Windows, macOS, or Linux).
2. Download Jython Standalone JAR: Visit the Jython website at http://www.jython.org/download.html and download the standalone JAR file of Jython, a Python interpreter for Java.
   
   
   
3. Open Burp Suite: Install and open Burp Suite on your computer.
4. Access Extender Tab: Within Burp Suite, navigate to the "Extender" tab.
   
   
   
5. Update Python Environment Settings: In the "Extender" tab, click on "Options." Under "Python Environment," update the location of the Jython Standalone JAR you downloaded. Click on "Select File" and choose the downloaded Jython JAR file.
   
   
   
6. Download Trishul.py File: Obtain the "trishul.py" file from the relevant repository. This file is needed to add the Trishul extension to Burp Suite. https://github.com/gauravnarwani97/Trishul
   
   
   
7. Add Trishul Extension: In the "Extender" tab under "Burp Extensions," click on "Add." Choose "Extension Type" as Python and provide the location of the "trishul.py" file. Click "Next" to proceed.
   
   
   
8. Extension Installation: Wait for the extension to finish installing. You'll see a new tab added to your Burp Suite named "Trishul."
   
   
   
9. Access Trishul Tab: Click on the "Trishul" tab within Burp Suite to access the automatic vulnerability detection features provided by the Trishul extension.

Using Trishul

With Trishul successfully installed, you can now utilize it in your security testing process. Trishul is designed to be seamlessly integrated into Burp Suite, making it easy to use. Here's a simplified process to get started with Trishul:

To identify vulnerabilities in requests, you can use Trishul in two ways:

1. Manual Request Submission: You can manually send each request to Trishul for analysis.
2. Automatic Scope-Based Testing: Alternatively, you can opt to perform automated vulnerability testing on all requests within a defined scope, typically associated with a specific website.

Both methods will be elaborated upon in the following sections for a more detailed understanding.

Usage #1: When installing Trishul, we augment the right-click context menu for various requests. After the installation, when you right-click any request within the Proxy, Target, or Repeater tabs, you'll notice a new option labeled "Send a request to Trishul." This feature allows you to conveniently send any selected request to Trishul for testing and analysis.

Usage #2: To utilize this method, you should first include the website you wish to test within the defined scope. Afterward, activate the Intercept feature within Trishul. This setup enables Trishul to automatically test all incoming requests directed at the website within the specified scope.

After adding the website to the designated scope, navigate to the Trishul extension and activate the Intercept feature. This action enables Trishul to capture and analyze all incoming requests directed at the website included within the specified scope.

CHARACTERISTICS:

Some of the characteristics of Trishul are as follows: 

1. Automated Vulnerability Detection: Trishul is primarily designed to automate the detection of common web application vulnerabilities. It streamlines the process of identifying security issues, such as Cross-Site Scripting (XSS), SQL Injection, and Server-Side Template Injection.
2. Integration with Burp Suite: Trishul seamlessly integrates with Burp Suite, a widely used web application security testing tool. It leverages Burp Suite's extensibility to enhance vulnerability scanning capabilities.
3. Cross-Site Scripting (XSS) Detection: Trishul includes the capability to scan for and identify XSS vulnerabilities. These vulnerabilities can allow attackers to inject malicious scripts into web pages viewed by other users.
4. SQL Injection Detection: The extension is equipped to find SQL injection vulnerabilities, a serious security issue that can lead to unauthorized access to databases through malicious input.
5. Server-Side Template Injection Detection: Trishul assists in locating server-side template injection vulnerabilities. These vulnerabilities can enable attackers to execute arbitrary code on the server, potentially leading to serious data breaches and security breaches.
6. User-Friendly Interface: Trishul typically provides a user-friendly interface within Burp Suite. This interface simplifies the process of selecting the type of vulnerability you want to scan for and reviewing the results.
7. Clear and Understandable Results: Trishul is designed to offer results in a clear and understandable format, making it easier for security professionals and penetration testers to interpret the findings and take appropriate action.
8. Flexible Scanning Options: The extension typically allows you to select specific vulnerability types to scan for, providing flexibility based on the testing requirements of your web application.
9. Continual Development: Like many open-source projects and Burp Suite extensions, Trishul may undergo ongoing development and improvement. Users can expect updates and enhancements to its features over time.
