Web Application Bug Checklist

This repository provides a comprehensive checklist for identifying and addressing common bugs and vulnerabilities in web applications. Whether you're a developer, QA engineer, or security professional, this checklist will help ensure your web application is secure, reliable, and user-friendly.

Table of Contents

Introduction

Web applications are complex systems that require thorough testing to ensure they function as expected and are secure from threats. This checklist is designed to cover a wide range of potential issues, from security vulnerabilities to usability problems, helping you to deliver a robust and secure web application.

Checklist Categories

Authentication and Authorization

  • Login and Logout:

    • Ensure protection against brute force attacks.
    • Test for SQL injection vulnerabilities in login forms.
    • Verify proper session invalidation after logout.
  • Password Policies:

    • Enforce strong password policies.
    • Ensure secure storage of passwords (e.g., hashed and salted).
  • Authorization:

    • Prevent unauthorized access to resources.
    • Test for horizontal and vertical privilege escalation.

Session Management

  • Session ID Security:

    • Ensure session IDs are complex, unique, and securely generated.
    • Regenerate session IDs upon login.
  • Session Expiry:

    • Implement session expiration after inactivity.
  • Secure Cookies:

    • Mark session cookies as HttpOnly and Secure.

Input Validation

  • Cross-Site Scripting (XSS):

    • Test for reflected, stored, and DOM-based XSS vulnerabilities.
  • SQL Injection:

    • Ensure input fields are protected against SQL injection.
  • Cross-Site Request Forgery (CSRF):

    • Verify CSRF tokens are used for state-changing requests.
  • File Uploads:

    • Validate and sanitize file uploads.
    • Store uploaded files securely, ensuring they are non-executable.

Data Handling

  • Sensitive Data Exposure:

    • Encrypt sensitive data both at rest and in transit.
  • Data Integrity:

    • Validate and sanitize data before processing.
  • Error Handling:

    • Prevent error messages from exposing sensitive information.

Business Logic

  • Workflow Bypasses:

    • Test for ways to bypass critical steps in business processes.
  • Race Conditions:

    • Check for issues when multiple users interact with the same object or process simultaneously.
  • Rate Limiting:

    • Ensure rate limiting is implemented to prevent abuse.

User Interface and User Experience (UI/UX)

  • Responsiveness:

    • Ensure the application is responsive across different devices and screen sizes.
  • Accessibility:

    • Verify that the application meets accessibility standards (e.g., WCAG).
  • Error Messages:

    • Provide clear and user-friendly error messages.
  • Navigation:

    • Ensure that navigation is intuitive and consistent across the application.

Performance and Scalability

  • Load Testing:

    • Conduct load testing to identify performance bottlenecks.
  • Caching:

    • Implement appropriate caching strategies to improve performance.
  • Database Optimization:

    • Optimize database queries and indexing for efficiency.

Compliance and Legal

  • Data Privacy:

    • Ensure compliance with data privacy laws (e.g., GDPR, CCPA).
  • Terms of Service and Privacy Policy:

    • Provide clear and accessible terms of service and privacy policy documents.
