Ethical Web App Pen-Test

@kajal1992

Hello, I can perform a focused, manual-heavy penetration test of your web application, with particular emphasis on data validation, session management, authentication/authorization controls, and business-logic weaknesses. My approach combines Burp Suite, OWASP ZAP, manual request manipulation, session/token analysis, input validation testing, and targeted logic testing. I will work carefully within the agreed scope, avoid destructive techniques, and maintain clear testing evidence so every finding can be reproduced and verified. Deliverables: • Concise executive risk summary • Detailed, reproducible PoCs with affected endpoints and evidence • Severity/risk rating and prioritized remediation recommendations • Clear technical findings report • Short retest/verification report after remediation I have hands-on experience in VAPT, web/API security testing, vulnerability assessment, security auditing, and penetration-testing reporting, with a strong focus on manually validating vulnerabilities rather than relying solely on automated scanners. I can begin after the NDA and access details are provided. I am also comfortable testing production systems conservatively and following strict rules of engagement. I would be happy to discuss the application architecture, scope, credentials, and expected timeline before starting.

Hi there, I noticed you need a focused pen-test on a production web app with special attention to data validation and session management—two areas attackers love to exploit. I'll run both automated scans and thorough manual logic testing, staying strictly within agreed scope and documenting everything for reproducibility. What I'll do: ✅ Automated + manual testing for data validation flaws (XSS, SQLi, injection) and session management weaknesses (token handling, fixation, hijacking) ✅ Full documentation: executive risk summary, step-by-step PoC for each finding, remediation steps ranked by priority ✅ Retest pass after you apply fixes to verify each fix works ✅ Full audit trail so your team can reproduce any finding independently Skills & experience: ✅ Burp Suite, OWASP ZAP, Nmap, and manual logic flaw testing ✅ Web app security: OWASP Top 10, session/token analysis, authentication flaws ✅ Risk assessment and remediation roadmaps ✅ Detailed documentation for reproducibility and compliance ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews Why me: I deliver clear, actionable reports—not just tool output—and I'm available for clarification throughout the engagement. One question: will the testing be against a staging environment, or do you need me to test against production with minimal impact? I can deliver in 7 days for 52,000 INR and can start right now.

Hello, I have strong skills in web security and penetration testing with focus on data validation and session management. I use tools like Burp Suite and OWASP ZAP along with manual testing to uncover logic flaws. My approach is structured, non‑destructive, and fully documented so you can reproduce every finding. I will provide a clear executive summary, detailed proof‑of‑concepts, and prioritized remediation advice, followed by a retest verification. I can start immediately and deliver within the agreed timeline. Regards,

Data validation and session management are exactly where production apps tend to leak: input that's sanitized in the UI but not at the API, or a session token that survives logout or a password change. Most of my testing is manual. I map every endpoint and role from your architecture notes, then cover the OWASP Top 10 plus the logic flaws scanners miss, like IDOR and race conditions on state-changing requests. Every finding gets a CVSS score, reproduction steps with request and response captures, and a fix ranked by priority, followed by a short retest pass once you've patched. I've spent 8 years in software engineering with more than 60 delivered freelance contracts. My security work covers web app penetration tests, audits, and a past role analyzing vulnerabilities in widely used open source Python packages. One question before the NDA: does staging share a database or auth provider with production? That decides how carefully I run session and injection tests. Timeline depends on endpoint count. Thamer

Happy to do this, and the first thing I would say is the thing that separates a real pentester from someone you should not let near a production app: nothing happens until the authorisation is in writing. A signed engagement that names the exact target scope, the testing window, my source IPs, what is explicitly out of bounds, and your written permission to test. On a production app that document is the line between a penetration test and an offence, and it protects you as much as me. Testing production also means agreeing a rate limit and a stop signal, so a test never becomes an outage. On the two areas you named, briefly, so you can judge that I actually work these rather than run a scanner: Data validation is not just injection. It is every place user input crosses a trust boundary: the obvious SQL and XSS, but also mass assignment, insecure deserialization, file uploads, and SSRF — the one most often missed on modern apps. Session management I test for fixation, whether tokens rotate on privilege change, cookie flags and SameSite, token lifetime and revocation, and IDOR — whether one user's session reaches another user's objects by changing an id, consistently the highest-impact finding on real apps. Deliverable: findings ranked by real exploitability with reproduction steps, not a raw scanner dump, plus a retest of the fixes. Sign the NDA and share the staging URL and scope, and I will send the rules-of-engagement document before touching anything.

@brunogfc

Hi — focused, non-destructive web app pen-testing is my daily work, and your scope (input validation + session management) is exactly where I live. Approach: 1) Recon + full auth/session mapping. 2) Manual testing (OWASP-aligned): injection, IDOR/broken access control, session fixation & rotation, cookie/JWT flaws, CSRF, business-logic abuse. 3) Verified PoCs only — zero false positives, each with reproducible step-by-step + request/response evidence. Deliverables: executive risk summary, per-issue PoC, remediation ranked by severity, and a free retest after your fixes. I sign your NDA first, stay strictly in scope, and never run destructive payloads against production. I can start as soon as I have the NDA + staging URL. Happy to jump on a short scoping call to lock the rules of engagement.

Hi, I’d like to help with the penetration test of your web application. I have hands-on experience with web security testing, vulnerability assessment, Burp Suite, Nmap, and testing web applications in controlled environments. For this project, I would mainly focus on the areas you mentioned: -Data validation and input handling -Session management and cookie security -Authentication and authorization -Access control issues -Common web application vulnerabilities -Business logic issues where applicable I’ll start by reviewing the scope and application structure, then manually test the relevant functionality and use Burp Suite to inspect and modify requests where needed. Any confirmed issue will be documented with clear reproduction steps, evidence, impact, and a practical fix. I’ll stay within the agreed scope and avoid any destructive testing. I can complete the initial assessment and report within 3–4 days, depending on the application size. I can also perform the requested retest after the fixes are applied. <Important>: Before testing begins, please provide an official written authorization confirming that I am permitted to conduct the security assessment on the specified targets. I will test only within the approved scope and will not perform destructive actions or intentionally cause any damage. I’d be happy to share my relevant security projects and experience.

@AppSec1998

I have Deep Expertise in securing Applications, and currently working as a Senior Security Engineer at a top fintech organization of India. This is my 3rd organization where I have discovered critical issues and have collaborated with the developers to remediate the same. I rely mostly on Manual Pentesting to find out issues that are rarely discovered by Scanners, and use a combination of both to deliver timely yet accurate results. I have eWPTX, eMAPT and CRTP Certifications.

@gemini530

What makes me the best fit for this project is my **deep knowledge of both web development and penetration testing**. Because I understand how web applications are built, I can look beyond automated scans and identify security weaknesses at the application, API, authentication, authorization, and business-logic levels. I have hands-on knowledge of **web application security, OWASP Top 10, vulnerability assessment, manual testing, reconnaissance, and penetration testing**, using tools such as Burp Suite, Nmap, SQLMap, Nikto, Nuclei, and Kali Linux. My development background also helps me understand how vulnerabilities are introduced in code and how they can be properly validated and remediated. I focus on finding real, exploitable security issues while minimizing false positives and providing clear, actionable recommendations. I can approach your project from both sides: **thinking like a developer to understand the application and thinking like an ethical hacker to identify how it could be attacked.**

@swakalps23

Hi, Your requirement stood out because you’re looking beyond automated scans and specifically need manual, logic-focused security testing around data validation and session management. I’m an Application Security (AppSec) Practitioner with hands-on experience testing web applications, APIs, mobile applications, and network environments. I focus on identifying and manually validating vulnerabilities that automated tools can miss. My approach: • Data validation: input manipulation, injection, parameter tampering, validation bypasses, and business logic flaws. • Session management: session fixation, token handling, lifecycle/invalidation, cookie security, and authentication-state issues. • Manual testing of workflows, authorization boundaries, and application logic. • Strict adherence to scope with non-destructive testing suitable for production. Deliverables: • Executive summary with overall risk • Detailed findings with reproducible PoCs and evidence • Prioritized remediation recommendations • Retest summary after fixes I can typically complete a focused assessment within 3–5 business days, depending on scope and complexity. I’m comfortable working under an NDA and following clearly defined Rules of Engagement. My goal is not to deliver scanner-generated alerts, but to validate real security impact and provide practical, reproducible findings your team can act on. Best regards, Swakalp Shukla

Hello, I believe this project aligns perfectly with my manual testing methodology. As an active CTF player, I prefer manual testing over automated scanning because I enjoy going deep into the application to find complex bugs. I recently completed a project (I cannot share the organization's name due to an NDA) where I found multiple critical vulnerabilities, including RCE and unauthenticated SQLi. I also uncovered several high-severity issues, such as broken access control leading to privilege escalation and stored XSS leading to account takeover, alongside some lower-severity bugs. Since yours is a production application, I want to assure you that I test for these critical flaws safely and strictly avoid destructive techniques. My methodology is exhaustive; I will do my best to cover every functionality and angle to deliver a comprehensive penetration test. My final report will include everything you requested: an executive summary, step-by-step PoCs, prioritized remediation advice, and I am fully available for the verification retest. While I cannot give you an exact timeline without knowing the nature and size of the application, my comprehensive testing approach usually takes about a week based on your description. I do not have formal certifications, but I regularly practice web CTFs on platforms like HackTheBox and DreamHack to stay sharp, and I am currently pursuing the CWES and CWEE paths to further my learning.
