API Testing — Deep Dive

Deep-Dive Lab Playbook — Every PortSwigger lab variant with exact payloads, bypass techniques, and zero-day extensions. 🟢 Apprentice 🟡 Practitioner 🔴 Expert

When to Use

  • BSCP certification prep
  • Real-world bug bounty hunting
  • Building exploitation chains
  • Understanding bypass techniques

Prerequisites

  • Burp Suite Professional
  • Burp Collaborator / interactsh
  • Browser with proxy configured

Workflow

Phase 1: Reconnaissance

  • Identify input vectors, parameters, and application behavior.

Phase 2: Exploitation

  • Apply standard lab payloads.

Phase 3: Zero-Day Escalation

  • Fuzz filters, bypass WAFs, and chain with other vulns.

Lab Playbooks

Lab 1: Exploiting documentation 🟢 APPRENTICE

Find /api docs endpoint → discover /api/user/carlos DELETE endpoint → delete user.

Lab 2: Server-side param pollution query 🟡 PRACTITIONER

POST /forgot-password HTTP/1.1

username=administrator%26field=reset_token

%26 = & → injects additional parameter into server-side API call → leaks reset token.

Lab 3: Unused API endpoint 🟡 PRACTITIONER

Change GET /api/products/1/price to PATCH method:

{"price":0}

→ Buy product for $0.

Lab 4: Mass assignment 🟡 PRACTITIONER

{"chosen_discount":{"percentage":100}}

Include discount object in checkout request → 100% discount applied.

Lab 5: Param pollution REST URL 🟡 PRACTITIONER

username=administrator#

Server constructs: /api/users/administrator#/field → # truncates path → returns full user object with token.

Blue Team Detection

  • Monitor access logs for anomalous payloads.
  • Implement strict input validation and parameterized queries where applicable.
  • Create WAF rules masking generic attack patterns.

Zero-Day Research

When standard technique fails:

  1. Identify the filter/WAF
  2. Fuzz with Burp Intruder custom wordlists
  3. Search GitHub/Twitter for new bypasses
  4. Chain with other vulns for escalation
  5. Try encoding variants: URL, double-URL, unicode, hex

Key Concepts

ConceptDescription
PortSwigger VectorsStandardized approaches to vulnerability classes.
Payload EncodingModifying payloads to bypass basic string matching WAFs.

Impact Explanation: [Impact]

🔵 Blue Team

  • Deploy robust WAF rules to detect anomalies.
  • Monitor logs for unusual access patterns.

🛡️ Remediation & Mitigation Strategy

  • Input Validation: Sanitize and strictly type-check all inputs.
  • Least Privilege: Constrain component execution bounds.

概要と使いどころ

Exploit pervasive logical flaws in Multi-Factor Authentication (MFA/2FA) implementations to bypass the secondary authentication challenge entirely. Techniques include response manipulation, referal spoofing, token reuse, and predictable backup codes.

Execute AS-REP Roasting to extract and crack the NTLM hashes of Active Directory user accounts that have the "Do not require Kerberos preauthentication" flag explicitly enabled. This attack generates a recoverable Ticket Granting Ticket (TGT) without requiring the attacker to authenticate first.

AD Certificate Services attack playbook. Use when targeting misconfigured AD CS for privilege escalation via ESC1-ESC13 template abuse, NTLM relay to enrollment, CA officer abuse, and certificate-based persistence.
