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

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:
Open Burp Suite and create/open project
Go to Proxy > Intercept tab
Click Open Browser to launch preconfigured browser
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
Continue forwarding subsequent requests until page loads
View HTTP History
Access complete traffic log:
Go to Proxy > HTTP history tab
Click any entry to view full request/response
Sort by clicking column headers (# for chronological order)
Use filters to focus on relevant traffic
Phase 2: Modifying Requests
Intercept and Modify
Change request parameters before forwarding:
Enable interception: Intercept on
Trigger target request in browser
Locate parameter to modify in intercepted request
Edit value directly in request editor
Click Forward to send modified request
Common Modification Targets
Target
Example
Purpose
Price parameters
price=1
Test business logic
User IDs
userId=admin
Test access control
Quantity values
qty=-1
Test input validation
Hidden fields
isAdmin=true
Test privilege escalation
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.
Phase 3: Setting Target Scope
Define Scope
Focus testing on specific target:
Go to Target > Site map
Right-click target host in left panel
Select Add to scope
When prompted, click Yes to exclude out-of-scope traffic
Filter by Scope
Remove noise from HTTP history:
Click display filter above HTTP history
Select Show only in-scope items
History now shows only target site traffic
Scope Benefits
Reduces clutter from third-party requests
Prevents accidental testing of out-of-scope sites
Improves scanning efficiency
Creates cleaner reports
Phase 4: Using Burp Repeater
Send Request to Repeater
Prepare request for manual testing:
Identify interesting request in HTTP history
Right-click request and select Send to Repeater
Go to Repeater tab to access request
Modify and Resend
Test different inputs efficiently:
1. View request in Repeater tab
2. Modify parameter values
3. Click Send to submit request
4. Review response in right panel
5. Use navigation arrows to review request history
Repeater Testing Workflow
Original Request:
GET /product?productId=1 HTTP/1.1
Test 1: productId=2 → Valid product response
Test 2: productId=999 → Not Found response
Test 3: productId=' → Error/exception response
Test 4: productId=1 OR 1=1 → SQL injection test
