⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

1. Ask the user to state the exact target URL, IP, account, or resource.
2. Ask the user to confirm written authorization and the permitted scope.
3. Show the exact command(s) and explain their expected effect.
4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.

Burp Suite Web Application Testing

Purpose

Execute comprehensive web application security testing using Burp Suite's integrated toolset, including HTTP traffic interception and modification, request analysis and replay, automated vulnerability scanning, and manual testing workflows. This skill enables systematic discovery and exploitation of web application vulnerabilities through proxy-based testing methodology.

Inputs / Prerequisites

Required Tools

• Burp Suite Community or Professional Edition installed
• Burp's embedded browser or configured external browser
• Target web application URL
• Valid credentials for authenticated testing (if applicable)

Environment Setup

• Burp Suite launched with temporary or named project
• Proxy listener active on 127.0.0.1:8080 (default)
• Browser configured to use Burp proxy (or use Burp's browser)
• CA certificate installed for HTTPS interception

Editions Comparison

Outputs / Deliverables

Primary Outputs

• Intercepted and modified HTTP requests/responses
• Vulnerability scan reports with remediation advice
• HTTP history and site map documentation
• Proof-of-concept exploits for identified vulnerabilities

Core Workflow

Phase 1: Intercepting HTTP Traffic

Launch Burp's Browser

Navigate to integrated browser for seamless proxy integration:

1. Open Burp Suite and create/open project
2. Go to Proxy > Intercept tab
3. Click Open Browser to launch preconfigured browser
4. Position windows to view both Burp and browser simultaneously

Configure Interception

Control which requests are captured:

Proxy > Intercept > Intercept is on/off toggle

When ON: Requests pause for review/modification
When OFF: Requests pass through, logged to history

Intercept and Forward Requests

Process intercepted traffic:

1. Set intercept toggle to Intercept on
2. Navigate to target URL in browser
3. Observe request held in Proxy > Intercept tab
4. Review request contents (headers, parameters, body)
5. Click Forward to send request to server
6. Continue forwarding subsequent requests until page loads

View HTTP History

Access complete traffic log:

1. Go to Proxy > HTTP history tab
2. Click any entry to view full request/response
3. Sort by clicking column headers (# for chronological order)
4. Use filters to focus on relevant traffic

Phase 2: Modifying Requests

Intercept and Modify

Change request parameters before forwarding:

1. Enable interception: Intercept on
2. Trigger target request in browser
3. Locate parameter to modify in intercepted request
4. Edit value directly in request editor
5. Click Forward to send modified request

Common Modification Targets

Example: Price Manipulation

POST /cart HTTP/1.1
Host: target.com
Content-Type: application/x-www-form-urlencoded

productId=1&quantity=1&price=100

# Modify to:
productId=1&quantity=1&price=1

Result: Item added to cart at modified price.
