Hi, I reviewed your request for a full black-box penetration test of the production site, aligned to the OWASP Top 10, with special focus on authentication, authorization, validation, and session management. I’ll run a controlled assessment through your Nginx-reversed React + Vite application using realistic black-box flows, capturing evidence for React.js routes, session handling, and Web Security issues, including network security checks and SQL-related injection attempts where inputs touch the database. I’ll prioritize safety to avoid disruption for other users, provide clear proof with reproducible steps and remediation guidance, and deliver an executive summary plus a methodology mapping. Let’s discuss here now.

Full black-box coverage against the live environment, with authenticated and unauthenticated paths tested using the account you provide, is the right approach given the backup is already in place. - Recon and mapping: Nmap for network/service enumeration, then Burp Suite and OWASP ZAP for application-layer testing, covering the Nginx reverse proxy configuration (headers, TLS, misconfigurations) and the React/Vite front end's attack surface. - Authentication, authorization and session management: broken access control checks, session/token handling, IDOR testing, plus systematic input validation across all forms and API calls, mapped directly to OWASP Top 10 categories. - Open question: are the API endpoints documented (REST spec, Swagger, etc.) or should they be discovered through crawling and traffic analysis? This affects how much time goes into enumeration versus deep testing of known routes. Delivery fits the 7-day window you specified, ending with the full report (findings, risk ratings, PoC, remediation, executive summary, methodology, retest notes) in PDF and editable format. Treat the bid amount as an initial, orientative reference for the scope as described, not a final price — we'll confirm the exact figure once the API documentation question above is settled. Happy to do a quick 15-minute call here on Freelancer to align on scope, and you're welcome to check my profile and portfolio for related security work.

@melopgabriel

Hi, your site needs a full black-box test focused on the exact areas that usually break first: auth, authorization, input handling, and session control. I’ve done production-safe web application assessments before, including OWASP Top 10 coverage with Burp Suite, OWASP ZAP, Nmap, and careful manual testing. I’ll validate both unauthenticated and authenticated paths, look for privilege escalation, injection, session flaws, and any exposure in the React/Vite and Nginx layers. My approach is controlled and non-disruptive: map the attack surface, test each flow methodically, document every finding with proof, then provide clear remediation steps and retest guidance. You’ll get an executive summary, technical detail, and a report that is easy to act on. If you’d like, I can start with the production-safe methodology and timeline immediately. Best regards, Gabriel

Rough ballpark on the bid amount and timeline shown - real figures depend on the actual surface area once we dig in, so treat them as starting points. Your site is a React/Vite app sitting behind Nginx, and you want to know exactly how it holds up against the OWASP Top 10 in a real environment. That means black-box testing from the outside, then authenticated testing with the credentials you provide, with the heaviest focus on auth flows, session handling, and anything that touches user input or output. The end goal is a clear picture of what's exploitable today and a roadmap to fix it. Here's how we'd approach this: - Recon and surface mapping: passive recon first, then active scanning with Nmap and Nikto to map endpoints, headers, and exposed services without touching the app hard. - Unauthenticated testing: run OWASP ZAP and Burp Suite against public-facing routes, checking for injection points, misconfigurations, exposed error messages, and insecure Nginx headers. - Authenticated testing: use the credentials you supply to walk through auth and session flows, testing for broken access control, IDOR, privilege escalation, and improper token handling. - Input/output validation: manual and automated checks on every form, API call, and file upload path for XSS, SQLi, SSTI, and similar injection risks. - Report and retest pack: full PDF report with CVSS-rated findings, screenshots, reproducible PoC steps, an exec summary for non-technical readers, and a retest checklist so you can confirm each fix independently. After a short scope chat we'll put together a written proposal covering deliverables, timeline, and a firm price. Would a 15 minute call this week work to go over the scope before we commit to numbers? Best, 96 Studio

@roell3

Hi, I handle security assessments alongside ML and backend systems, including auth flows, API surfaces, and production-grade web stacks. The real challenge here is testing deeply without degrading live service. Session handling, token lifecycles, and privilege boundaries often hide subtle flaws. Input validation across client and proxy layers can also diverge, especially under authenticated states. Another risk area is ensuring findings are reproducible without relying on unstable conditions. How is traffic isolation handled during testing to avoid impacting real users? Are there rate limits or WAF rules that could skew results? Do you have logging or audit trails accessible for correlating test activity? I can align with your timeline once scope details are clarified.
