Web Application Penetration Testing

Categories: , , ,

Description

Goal: Learn how to find and remediate common web vulnerabilities using standard tools and methodologies.

Prerequisites:

  • Basic knowledge of web technologies (HTML, JavaScript, SQL).
  • Familiarity with HTTP requests and responses.

Tools and Technologies:

  • Vulnerable Web Apps: DVWA (Damn Vulnerable Web Application) or OWASP Juice Shop
  • Testing Tools: Burp Suite (Community Edition), OWASP ZAP, browser developer tools.

Steps:

  1. Set Up a Test Environment:
    • Install DVWA or Juice Shop on a local server or Docker container.
  2. Understand the OWASP Top 10:
    • Read about common vulnerabilities: XSS, SQLi, CSRF, etc.
  3. Use a Proxy Tool (e.g., Burp Suite):
    • Intercept requests, modify parameters, and see how the server responds.
  4. Find Vulnerabilities:
    • Attempt SQL injection: try ' OR '1'='1 type payloads in login forms.
    • Try Cross-Site Scripting: inject <script>alert('XSS');</script> in fields and see if it executes.
  5. Report Your Findings:
    • Note each vulnerability, its impact, possible exploitation scenarios, and remediation steps.
  6. Fix and Retest:
    • Implement mitigations such as input validation, parameterized queries, content security policies.
    • Test again to ensure the vulnerabilities are resolved.

Outcome:
You’ll gain hands-on experience in identifying and preventing common web app vulnerabilities and improve your penetration testing methodologies.
