Step 1: Prepare Your Tools & Environment
Tools Needed:
Burp Suite (or OWASP ZAP)
Nmap/Recon-ng for network reconnaissance
Python scripts or custom fuzzers
API testing tools like Postman
Wordlists (e.g., SecLists)
Environment Setup:
Set up Burp Suite as a proxy to intercept and modify traffic
Ensure you have valid credentials or session tokens if needed
Isolate testing environment to prevent accidental impact
Step 2: Reconnaissance & Initial Mapping
Review All Endpoints:
Use the list of 192 endpoints.
Use Burp Suite or Postman to send GET requests to each endpoint.
Check Responses for Sensitive Data:
Look for debug info, internal IPs, API keys, or secrets.
Save responses that contain sensitive info.
Identify Authentication & Authorization:
Determine which endpoints require login.
Test if you can access protected endpoints without credentials or with different user roles.
Step 3: Automate Basic Scanning & Fuzzing
Create a List of Payloads:
For injection points: SQLi, command injection, path traversal.
For parameter tampering: alter IDs, tokens.
Use Burp Intruder or ZAP Active Scan:
Target endpoints with parameters.
Fuzz with payloads like ' OR 1=1 --, ../, <script>alert(1)</script>.
Identify Weaknesses:
Look for injection points or error messages revealing vulnerabilities.
Step 4: Test Authentication & Session Management
Check for Session Fixation or Reuse:
Capture tokens or session cookies.
Replay or manipulate them to see if session fixation is possible.
Test for Privilege Escalation:
Access endpoints as a standard user.
Attempt to access admin or higher-privilege endpoints (/api/v2/accounts, /api/v2/collector,
etc.).
Look for Broken Access Controls:
Try changing resource IDs (e.g., user IDs) to access other users' data.
Step 5: API-Specific Testing
Test Data Exposure:
Check if sensitive data (e.g., user info, tokens) appears in responses.
Parameter Manipulation:
Alter parameters like id, type, token to see if insecure operations occur.
Undocumented Endpoints:
Review swagger.json and swagger.yaml.
Test endpoints with different HTTP methods and payloads.
Step 6: Check for Security Misconfigurations
CORS & CSRF:
Use browser dev tools or Burp to see if cross-origin requests are allowed.
Test if endpoints accept cross-site requests.
Token Security:
Inspect tokens from /api/token.
Check for weak or predictable tokens.
Step 7: Business Logic & Workflow Testing
Simulate Typical User Flows:
Log in, create a cart, make a purchase.
Attempt to bypass steps or manipulate data.
Test for Race Conditions or Replays:
Resubmit requests with the same data.
Check if duplicate actions occur.
Step 8: Document & Verify Vulnerabilities
Capture Proofs:
Screenshots, request/response logs.
Exploit code snippets.
Verify & Reproduce:
Ensure vulnerabilities are consistent.
Check if fixes are needed.
Step 9: Reporting
Prepare a detailed report with:
Endpoint details
Vulnerability description
Reproduction steps
Impact assessment
Recommended fixes
