Penetration Testing

Web Application Vulnerability Assessment and Penetration Testing (VAPT) to identify and validate real security risks across your application's functionality, workflows and integrations.

⊕

Service Overview

Web Application Penetration Testing focuses on identifying weaknesses that allow unintended access, data exposure or misuse of application functionality. We look at how users interact with the application, how requests are handled and how features behave when used outside their intended purpose.

This includes evaluating whether actions can be performed without proper authorization, whether sensitive data can be reached indirectly and whether application features can be chained together to produce outcomes you never designed for.

The goal is to determine what's actually exploitable in practice, what it allows and how it impacts the application and its users. Every finding is validated to make sure it represents real, actionable risk — not scanner noise.

// Attack Path Validation

From isolated weaknesses to real impact

Weaknesses are evaluated in the context of how the application operates end to end, showing how individual issues can be combined to access data, perform unauthorized actions or alter application behavior in ways that were never intended.

Benefits

[01]

Clear understanding of risk

You see exactly what can be exploited and what each issue enables — in plain language, not just severity scores.

[02]

Focus on what matters most

Findings are prioritised so the issues that create the highest real-world impact rise to the top of your fix list.

[03]

Confirmed real-world impact

Every reported issue is manually verified, so you know whether a weakness can actually be abused in practice.

[04]

Accurate behavior representation

Testing reflects how your application behaves under genuine attacker conditions, not just theoretical scenarios.

Why Choose HackersForce

A structured review of how your application behaves across user actions, system responses and component interactions — to identify the conditions that lead to unintended outcomes.

▸ How we approach testing

Testing starts with understanding how the application is actually used, then focuses on how features and workflows can be misused to identify where controls fail under real conditions.

✓ Public functionality and exposed endpoints (login, registration, public APIs)
✓ User actions across different roles and permissions (standard, admin, privileged)
✓ Business workflows and transaction flows (account creation, approvals, payments)
✓ Authorization checks on objects and operations (IDOR, forced browsing, escalation)
✓ Session handling and user-state transitions (session fixation, token reuse, logout)
✓ File upload and processing (unrestricted uploads, inclusion, storage access)
✓ Error handling and information disclosure (verbose errors, stack traces, debug data)
✓ Integrations and external dependencies (payment gateways, third-party APIs)
✓ API and service communication layers (REST, GraphQL, SOAP)
✓ Authentication and identity flows (OAuth, SAML, JWT, MFA bypass)
✓ Third-party libraries and components (outdated, vulnerable packages)
✓ Behavior under concurrent or unexpected actions (race conditions, state issues)

Engagements follow a repeatable, standards-aligned process so coverage is consistent and every finding is traceable from discovery to remediation.

01

Scoping & Rules of Engagement

We agree targets, test windows, credentials and constraints in writing before a single request is sent.

02

Reconnaissance & Mapping

We enumerate the application's surface, technologies, roles and workflows to plan where to dig.

03

Manual Exploitation

Aligned to OWASP WSTG, we test each class of weakness by hand and chain issues into real attack paths.

04

Validation & Impact Analysis

Each finding is confirmed with a proof-of-concept and rated using CVSS plus business-impact context.

05

Reporting & Free Retest

You get an executive summary and technical report, then we retest your fixes at no extra cost.

A sample of the issue classes we routinely uncover in web applications — every report ties each one to a concrete proof-of-concept and a remediation path.

⚠ SQL, NoSQL and command injection
⚠ Broken access control & IDOR
⚠ Authentication & session-management flaws
⚠ Cross-site scripting (stored, reflected, DOM)
⚠ Server-side request forgery (SSRF)
⚠ Insecure deserialization & object injection
⚠ Business-logic & workflow abuse
⚠ Security misconfiguration & exposed secrets
⚠ Vulnerable & outdated components
⚠ Cross-site request forgery (CSRF)
⚠ File-upload & path-traversal flaws
⚠ Race conditions & state inconsistencies

FAQs

Yes. We combine breadth and depth — broad vulnerability assessment to map your full attack surface, then hands-on penetration testing to confirm which weaknesses are genuinely exploitable and what they expose.
We recommend testing a staging environment that mirrors production. Where that isn't possible, we test production under a carefully agreed rules-of-engagement window to avoid disruption.
Yes, where they're in scope and you have authority to test them. Third-party APIs, payment gateways and identity providers are common sources of risk, so we assess how your application trusts and consumes them.
No. We test public, authenticated and internal applications. For authenticated and role-based testing we'll ask for accounts covering each privilege level so we can probe authorization properly.
We test conservatively by default and avoid destructive techniques unless explicitly authorised. Any potentially intrusive activity is agreed in advance and scheduled around your low-traffic windows.
Yes — a free retest is included. Once your team remediates, we re-verify each finding and update the report so you have documented proof the issues are closed.
An executive summary for stakeholders and a detailed technical report with CVSS-scored findings, reproduction steps, proof-of-concept evidence, business impact and prioritised remediation guidance — plus a retest report after fixes.
