Information Gathering/Recon
- Retrieve and analyze the robot.txt files by using a tool called GNU Wget.
- Examine the version of the software/database details, the error technical component, and bugs by the error codes and by requesting invalid pages
- Discover hidden and default content
- Implement techniques such as DNS inverse queries, DNS zone Transfers, and web-based DNS Searches
- Perform directory style searching and vulnerability scanning and probe for URLs, using tools such as NMAP and Nessus.
- By using a traditional Fingerprint Tool, such as Nmap, Amap, perform TCP/ICMP, and service Fingerprinting.
- Identify the entry point of the application using OWSAP ZAP, Burb Proxy, TemperIE, and WebscarabTemper Data.
- Identify the technologies used
- Map the attack surface
Test Handling of Access
- Authentication
- Test password quality rules
- Test for username enumeration
- Test resilience to password guessing
- Test any account recovery function
- Test any “remember me” function
- Test any impersonation function
- Test username uniqueness
- Check for unsafe distribution of credentials
- Test for fail-open conditions
- Test any multi-stage mechanisms
- Session handling
- Test tokens for meaning
- Test tokens for predictability
- Check for insecure transmission of tokens
- Check for disclosure of tokens in logs
- Check the map of tokens to sessions
- Check session termination
- Check for session fixation
- Check for cross-site request forgery
- Check cookie scope
- Access controls
- Understand the access control requirements
- Test effectiveness of controls, using multiple accounts if possible
- Test for insecure access control methods (request parameters, Referer header, etc.)
Test Handling of Input
- Fuzz all request parameters
- Test for SQL injection
- Identify all reflected data
- Test for reflected XSS
- Test for HTTP header injection
- Test for arbitrary redirection
- Test for stored attacks
- Test for OS command injections
- Test for path traversal
- Test for script injection
- Test for file inclusion
- Test for SMTP injection
- Test for native software flaws (buffer overflow, integer bugs, format strings)
- Test for SOAP injection
- Test for LDAP injection
- Test for XPath injection
Test Application Logic
- Identify the logic attack surface
- Test transmission of data via the client
- Test for reliance on client-side input validation
- Test any thick-client components (Java, ActiveX, Flash)
- Test multi-stage processes for logic flaws
- Test handling of incomplete input
- Test trust boundaries
- Test transaction logic
Assess Application Hosting
- Test segregation in shared infrastructures
- Test segregation between ASP-hosted applications
- Test for web server vulnerabilities
- Default credentials
- Default content
- Dangerous HTTP methods
- Proxy functionality
- Virtual hosting misconfiguration
- Bugs in web server software
Miscellaneous Tests
- Check for DOM-based attacks
- Check for frame injection
- Check for local privacy vulnerabilities
- Persistent cookies
- Caching
- Sensitive data in URL parameters
- Forms with autocomplete enabled
- Follow up any information leakage
- Check for weak SSL ciphers
