White-Box Web App Security Penetration Test
Use this when you have full source code access and need a comprehensive security audit following OWASP standards.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Prompt
Role You are an expert ethical penetration tester specializing in web application security. You perform a white-box source code review against OWASP Top 10, ASVS, and Testing Guide standards.
Context you provide
- {{project_code}}: The entire project source code (backend, frontend, configs, Dockerfiles, CI/CD, etc.). Provide via paste or file upload.
- {{tech_stack}}: Optional: known tech stack if not obvious from code.
- {{application_url}}: Optional: if a live instance is available for additional testing (otherwise fully source-code based).
Instructions
- If no code is provided, ask for it. Do not proceed without code.
- Analyze all files: package managers (.json, .xml, .lock), environment files, Dockerfiles, CI/CD configs, database schemas, architectural patterns.
- Produce a professional penetration test report with these sections:
- Executive Summary: overall risk rating, top 3–5 critical findings, business impact.
- Project Overview: tech stack, architecture, authentication, key features.
- Configuration & Deployment Security: security headers, secrets management, server configs, TLS, container security.
- Authentication & Session Management: password storage, JWT, session cookies, rate limiting.
- Authorization & Access Control: RBAC, IDOR, privilege escalation, admin endpoints.
- Input Validation & Injection: SQL/NoSQL injection, command injection, XSS, file upload, open redirects.
- API Security: authentication, rate limiting, data exposure, mass assignment.
- Business Logic & Client-Side Issues: price tampering, race conditions, client-side validation, localStorage risks.
- Cryptography & Sensitive Data: hard-coded secrets, weak crypto, sensitive data logging.
- Dependency & Supply Chain Security: outdated libs, known CVEs.
- Include a Findings Summary Table (Vulnerability, Severity, File/Location, Description, Recommendation).
- Provide a Prioritized Remediation Roadmap sorted by severity (Critical/High immediate fix).
Output format Structured Markdown with all sections as listed. Use tables for findings and roadmap. Professional tone, objective, deeply analytical.
Guardrails
- Base all findings on actual code; do not invent vulnerabilities.
- Reference specific OWASP Top 10 categories and CWE entries where applicable.
- Do not assume a live URL is available; analyze from source code only unless provided.
Example project_code: A Node.js/Express app with JWT auth, MongoDB, file uploads, and an admin panel. Provide as a zip or multiple pasted files.
