Problem

Web Server fuzzer that discovers & tests:

  • Hidden directories,
  • Virtual hosts,
  • API endpoints,
  • URL parameters, and
  • Subdomains
  1. Preparation & Info:

    • Define objective & Web Components to be tested & assessment vulnerabilities
    • Choose fuzzy tools for network mapping & enumerating.
  2. Files Enumeration:

    • Enumeration of directories and files to uncover hidden content i.e brute-force dir. names and file extensions to identify un-linked or forgotten resources.
    • Testing: Test discovered directories and files for common vulnerabilities such as directory traversal and insecure file uploads.
  3. Virtual Hosts:

    • Identify virtual hosts configured on the server by fuzzing the Host header with various subdomain values.
    • Assessment: Evaluate the discovered virtual hosts for configuration issues and vulnerabilities that might arise from improper isolation of web applications.
  4. API Endpoints:

    • Detect API endpoints by analysing common patterns and URL structures used in the application.
    • Vulnerability Testing: Test API endpoints for security flaws such as insecure data transmission, improper authentication, and authorisation, as well as injection vulnerabilities.
  5. Parameters Fuzzing:

    • Fuzz URL parameters to uncover vulnerabilities like SQL injection, cross-site scripting (XSS), remote code execution, and parameter pollution.
    • Payloads: Use a variety of payloads and encoding techniques to ensure comprehensive coverage of potential attack vectors.
  6. Custom Test Cases:

    • Allow users to create and integrate custom test cases to target specific application logic or unique vulnerabilities.
    • Execution: Execute custom test cases in conjunction with standard fuzzing techniques to maximise the depth and breadth of security testing.
  7. Subdomains:

    • Perform DNS enumeration and brute-forcing to identify subdomains associated with the main domain.
    • Security Testing: Assess the discovered subdomains for common vulnerabilities and mis-configuration that could expose the application to risk.
  8. Reporting Findings:

    • Prepare detailed reports highlighting identified vulnerabilities, their severity, and potential impact.
    • Include specific examples and explanations to aid in understanding and remediation.
    • Prioritize Issues: Rank the discovered vulnerabilities based on their severity and potential impact to help prioritize remediation efforts.
  9. Mitigation:

    • Provide actionable recommendations for addressing the identified vulnerabilities, including secure coding practices, configuration adjustments, and updates to dependencies.

Methodologies

Integrate Fixes: Collaborate with the development team to implement the recommended fixes, ensuring the application is secured before deployment. Expected Solution:

  1. Early Detection of Vulnerabilities: Identifying security issues early in the development process, allowing for timely remediation.
  2. Improved Code Quality: Encouraging secure coding practices and reducing the likelihood of introducing security flaws.
  3. Increased Security Awareness: Raising awareness among developers about common security issues and how to avoid them.
  4. Enhanced Application Security: Reducing the risk of exploitation by addressing vulnerabilities before the application is deployed to production.
