Problem
Web Server fuzzer that discovers & tests:
- Hidden directories,
- Virtual hosts,
- API endpoints,
- URL parameters, and
- Subdomains
-
Preparation & Info:
- Define objective & Web Components to be tested & assessment vulnerabilities
- Choose fuzzy tools for network mapping & enumerating.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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:
- Early Detection of Vulnerabilities: Identifying security issues early in the development process, allowing for timely remediation.
- Improved Code Quality: Encouraging secure coding practices and reducing the likelihood of introducing security flaws.
- Increased Security Awareness: Raising awareness among developers about common security issues and how to avoid them.
- Enhanced Application Security: Reducing the risk of exploitation by addressing vulnerabilities before the application is deployed to production.
