Fast Testing Checklist

A combination of my own methodology and the Web Application Hacker's Handbook Task checklist, as a Github-Flavored Markdown file

Contents

• Recon and analysis
• Test handling of access
• Test handling of input
• Test application logic
• Assess application hosting
• Miscellaneous tests

Task Checklist

App Recon and analysis

• Map visible content
• Discover hidden & default content
• Test for debug parameters
• Identify data entry points
• Identify the technologies used
• Research existing vulnerabilitties in technology
• Gather wordlists for specific techniology (Assetnote ones are excellent)
• Map the attack surface (Spider)
• Identify all javascript files for later analysis

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 mapping 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 injection
• 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 for SSRF and HTTP Redirrects in all redirecting parameters

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 mis-configuration
• 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
