Burp Suite Testing V3

Burp Suite Web Application Testing

Overview

This public intake copy packages plugins/antigravity-bundle-security-engineer/skills/burp-suite-testing from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments. # Burp Suite Web Application Testing

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Purpose, Inputs / Prerequisites, Outputs / Deliverables.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: 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....
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

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
5. Set intercept toggle to Intercept on
6. Navigate to target URL in browser
7. Observe request held in Proxy > Intercept tab

Imported Workflow Notes

Imported: 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.

Phase 3: Setting Target Scope

Define Scope

Focus testing on specific target:

1. Go to Target > Site map
2. Right-click target host in left panel
3. Select Add to scope
4. When prompted, click Yes to exclude out-of-scope traffic

Filter by Scope

Remove noise from HTTP history:

1. Click display filter above HTTP history
2. Select Show only in-scope items
3. 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:

1. Identify interesting request in HTTP history
2. Right-click request and select Send to Repeater
3. 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

Analyze Responses

Look for indicators of vulnerabilities:

• Error messages revealing stack traces
• Framework/version information disclosure
• Different response lengths indicating logic flaws
• Timing differences suggesting blind injection
• Unexpected data in responses

Phase 5: Running Automated Scans

Launch New Scan

Initiate vulnerability scanning (Professional only):

1. Go to Dashboard tab
2. Click New scan
3. Enter target URL in URLs to scan field
4. Configure scan settings

Scan Configuration Options

Monitor Scan Progress

Track scanning activity:

1. View task status in Dashboard
2. Watch Target > Site map update in real-time
3. Check Issues tab for discovered vulnerabilities

Review Identified Issues

Analyze scan findings:

1. Select scan task in Dashboard
2. Go to Issues tab
3. Click issue to view:
   • Advisory: Description and remediation
   • Request: Triggering HTTP request
   • Response: Server response showing vulnerability

Phase 6: Intruder Attacks

Configure Intruder

Set up automated attack:

1. Send request to Intruder (right-click > Send to Intruder)
2. Go to Intruder tab
3. Define payload positions using § markers
4. Select attack type

Attack Types

Configure Payloads

Positions Tab:
POST /login HTTP/1.1
...
username=§admin§&password=§password§

Payloads Tab:
Set 1: admin, user, test, guest
Set 2: password, 123456, admin, letmein

Analyze Results

Review attack output:

• Sort by response length to find anomalies
• Filter by status code for successful attempts
• Use grep to search for specific strings
• Export results for documentation

Imported: 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.

Examples

Example 1: Ask for the upstream workflow directly

Use @burp-suite-testing-v3 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @burp-suite-testing-v3 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @burp-suite-testing-v3 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @burp-suite-testing-v3 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Imported Usage Notes

Imported: Examples

Example 1: Business Logic Testing

Scenario: E-commerce price manipulation

1. Add item to cart normally, intercept request
2. Identify price=9999 parameter in POST body
3. Modify to price=1
4. Forward request
5. Complete checkout at manipulated price

Finding: Server trusts client-provided price values.

Example 2: Authentication Bypass

Scenario: Testing login form

1. Submit valid credentials, capture request in Repeater
2. Send to Repeater for testing
3. Try: username=admin' OR '1'='1'--
4. Observe successful login response

Finding: SQL injection in authentication.

Example 3: Information Disclosure

Scenario: Error-based information gathering

1. Navigate to product page, observe productId parameter
2. Send request to Repeater
3. Change productId=1 to productId=test
4. Observe verbose error revealing framework version

Finding: Apache Struts 2.5.12 disclosed in stack trace.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Test only authorized applications
• Configure scope to prevent accidental out-of-scope testing
• Rate-limit scans to avoid denial of service
• Document all findings and actions
• Community Edition lacks automated scanner
• Some sites may block proxy traffic
• HSTS/certificate pinning may require additional configuration

Imported Operating Notes

Imported: Constraints and Guardrails

Operational Boundaries

• Test only authorized applications
• Configure scope to prevent accidental out-of-scope testing
• Rate-limit scans to avoid denial of service
• Document all findings and actions

Technical Limitations

• Community Edition lacks automated scanner
• Some sites may block proxy traffic
• HSTS/certificate pinning may require additional configuration
• Heavy scanning may trigger WAF blocks

Best Practices

• Always set target scope before extensive testing
• Use Burp's browser for reliable interception
• Save project regularly to preserve work
• Review scan results manually for false positives

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-bundle-security-engineer/skills/burp-suite-testing, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Troubleshooting Notes

Imported: Troubleshooting

Browser Not Connecting Through Proxy

• Verify proxy listener is active (Proxy > Options)
• Check browser proxy settings point to 127.0.0.1:8080
• Ensure no firewall blocking local connections
• Use Burp's embedded browser for reliable setup

HTTPS Interception Failing

• Install Burp CA certificate in browser/system
• Navigate to http://burp to download certificate
• Add certificate to trusted roots
• Restart browser after installation

Slow Performance

• Limit scope to reduce processing
• Disable unnecessary extensions
• Increase Java heap size in startup options
• Close unused Burp tabs and features

Requests Not Being Intercepted

• Verify "Intercept on" is enabled
• Check intercept rules aren't filtering target
• Ensure browser is using Burp proxy
• Verify target isn't using unsupported protocol
