Recon phase

Large: a whole company with multiple domains
Medium: a single domain
Small: a single website

Large scope

Get for IP ranges (, , , )
Review latest
Get relationships by registrants ()
Go to medium scope for each domain

Medium scope

( or with all available API keys)
Subdomain bruteforce ( with )
Permute subdomains ( or with )
Identify alive subdomains ()
()
Check for ()
search
Subdomains recursive search
Take screenshots (, , )

Small scope

Try to locate /robots.txt , /crossdomain.xml /clientaccesspolicy.xml /sitemap.xml and /.well-known/
Review comments on source code (Burp Engagement Tools)
Locate admin and login panel

Network

Check ICMP packets allowed

Preparation

Study site structure
Make a list with all possible test cases
Understand the business area and what their customer needs
Get a list of every asset (all_subdomains.txt, live_subdomains.txt, waybackurls.txt, hidden_directories.txt, nmap_results.txt, GitHub_search.txt, altdns_subdomain.txt, vulnerable_links.txt, js_files.txt)

User management

Registration

Duplicate registration (try with uppercase, +1@..., dots in name, etc)
Overwrite existing user (existing user takeover)
Username uniqueness
Weak password policy (user=password, password=123456,111111,abcabc,qwerty12)
Weak registration implementation or allows disposable email addresses
Fuzz after user creation to check if any folder have been overwritten or created with your profile name
Add only spaces in password
Long password (>200) leads to DoS
Corrupt authentication and session defects: Sign up, don't verify, request change password, change, check if account is active.
Try to re-register repeating same request with same password and different password too
If JSON request, add comma {“email”:“victim@mail.com”,”hacker@mail.com”,“token”:”xxxxxxxxxx”}
Lack of confirmation -> try to register with company email.
Check OAuth with social media registration
Check state parameter on social media registration
Try to capture integration url leading integration takeover
Check redirections in register page after login
Rate limit on account creation
XSS on name or email

Authentication

Username enumeration
Resilience to password guessing
Account recovery function
"Remember me" function
Impersonation function
Unsafe distribution of credentials
Fail-open conditions
Multi-stage mechanisms
Auto-complete testing
Lack of password confirmation on change email, password or 2FA (try change response)
Weak login function over HTTP and HTTPS if both are available
User account lockout mechanism on brute force attack
In OTP check guessable codes and race conditions
OTP, check response manipulation for bypass
OTP, try bruteforce
Browser cache weakness (eg Pragma, Expires, Max-age)
After register, logout, clean cache, go to home page and paste your profile url in browser, check for "login?next=accounts/profile" for open redirect or XSS with "/login?next=javascript:alert(1);//"

Session

Session handling
Test tokens for meaning
Test tokens for predictability
Insecure transmission of tokens
Disclosure of tokens in logs
Mapping of tokens to sessions
Session termination
Session fixation
Cookie scope
Decode Cookie (Base64, hex, URL etc.)
Cookie expiration time
Check HTTPOnly and Secure flags
Use same cookie from a different effective IP address or system
Access controls
Effectiveness of controls using multiple accounts
Insecure access control methods (request parameters, Referer header, etc)
Check for concurrent login through different machine/IP
Weak generated security questions
Path traversal on cookies
Reuse cookie after session closed
Logout and click browser "go back" function (Alt + Left arrow)
2 instances open, 1st change or reset password, refresh 2nd instance
With privileged user perform privileged actions, try to repeat with unprivileged user cookie.

Profile/Account details

Find parameter with user id and try to tamper in order to get the details of other users
Change email id and update with any existing email id. Check if its getting validated on server or not.
Check any new email confirmation link and what if user doesn't confirm.
CSV import/export: Command Injection, XSS, macro injection
Imagetragick in picture profile upload
Account deletion option and try to reactivate with "Forgot password" feature
Try bruteforce enumeration when change any user unique parameter.
Check application request re-authentication for sensitive operations
Try parameter pollution to add two values of same field
Check different roles policy

Forgot/reset password

Invalidate session on Logout and Password reset
Uniqueness of forget password reset link/code
Reset links expiration time
Find user id or other sensitive fields in reset link and tamper them
Request 2 reset passwords links and use the older
Check if many requests have sequential tokens
Use username@burp_collab.net and analyze the callback
Host header injection for token leakage
Add X-Forwarded-Host: evil.com to receive the reset link with evil.com
Email crafting like victim@gmail.com@target.com
IDOR in reset link
Capture reset token and use with other email/userID
No TLD in email parameter
User carbon copy email=victim@mail.com%0a%0dcc:hacker@mail.com
Long password (>200) leads to DoS
No rate limit, capture request and send over 1000 times
Check encryption in reset password token
Token leak in referer header
Append second email param and value
Understand how token is generated (timestamp, username, birthdate,...)
Response manipulation

Input handling

Fuzz all request parameters (if got user, add headers to fuzzer)
Identify all reflected data
RCE via Referer Header
SQL injection via User-Agent Header
Arbitrary redirection
Stored attacks
OS command injection
Script injection
File inclusion
SMTP injection
Native software flaws (buffer overflow, integer bugs, format strings)
SOAP injection
LDAP injection
SSI Injection
XPath injection
Code Injection (<h1>six2dez</h1> on stored param)
xmlrpc.php DOS and user enumeration
HTTP dangerous methods OPTIONS PUT DELETE
Insecure deserialization

Error handling

Access custom pages like /whatever_fake.php (.aspx,.html,.etc)
Add multiple parameters in GET and POST request using different values
Add "[]", "]]", and "[[" in cookie values and parameter values to create errors
Generate error by giving input as "/~randomthing/%s" at the end of URL
Use Burp Intruder "Fuzzing Full" List in input to generate error codes
Try different HTTP Verbs like PATCH, DEBUG or wrong like FAKE

Application Logic

Identify the logic attack surface
Test transmission of data via the client
Test for reliance on client-side input validation
Thick-client components (Java, ActiveX, Flash)
Multi-stage processes for logic flaws
Handling of incomplete input
Trust boundaries
Transaction logic
Implemented CAPTCHA in email forms to avoid flooding
Tamper product id, price or quantity value in any action (add, modify, delete, place, pay...)
Tamper gift or discount codes
Reuse gift codes
Try parameter pollution to use gift code two times in same request
Try stored XSS in non-limited fields like address
Check in payment form if CVV and card number is in clear text or masked
Check if is processed by the app itself or sent to 3rd parts
IDOR from other users details ticket/cart/shipment
Check PRINT or PDF creation for IDOR
Check unsubscribe button with user enumeration
Parameter pollution on social media sharing links
Change POST sensitive requests to GET

Other checks
