Web Application Penetration Testing
Deep-dive assessment of web applications using OWASP methodology to uncover critical vulnerabilities.
Web Application Penetration Testing
A web application penetration test goes far beyond automated scanning. Intelliroot's certified testers manually probe your application for logic flaws, authentication weaknesses, injection vulnerabilities, and business-logic bypasses that scanners consistently miss. Every test is conducted against the OWASP Web Security Testing Guide and rated using CVSS 3.1.
Whether you need a black-box assessment simulating an external attacker, a grey-box test with authenticated access, or a white-box review using full source code, we tailor the engagement to your risk profile and compliance obligations.
Why Your Organisation Needs Web App Testing
Web Apps Are the #1 Attack Vector
Over 75% of cyberattacks target the application layer. Scanners catch less than 30% of critical vulnerabilities found by manual testing.
Compliance Requires It
PCI DSS, ISO 27001, SOC 2, RBI, SEBI, and CERT-In all mandate periodic penetration testing of internet-facing applications.
Business Logic Flaws Are Invisible
Price manipulation, account takeover, and privilege escalation through logic flaws cannot be detected by automated tools — only skilled manual testing finds them.
Prioritised, Actionable Results
Every finding includes proof-of-concept evidence, risk rating, business impact, and step-by-step remediation guidance — not just a CVE list.
Ideal for These Organisations
What We Test
Authentication & Session Management
- Brute force and credential stuffing resistance
- Multi-factor authentication bypass
- Session token entropy and fixation
- Insecure password reset flows
- OAuth 2.0 and SSO implementation flaws
Injection & Data Exposure
- SQL, NoSQL, LDAP, and OS command injection
- Cross-Site Scripting (Reflected, Stored, DOM)
- XML External Entity (XXE) processing
- Server-Side Request Forgery (SSRF)
- Sensitive data exposure and insecure storage
Access Control & Business Logic
- Broken Object Level Authorisation (IDOR)
- Horizontal and vertical privilege escalation
- Business logic bypass (price manipulation, workflow abuse)
- Mass assignment and parameter tampering
- Insecure Direct Object Reference
Infrastructure & Configuration
- Security misconfigurations and default credentials
- HTTP security headers assessment
- TLS/SSL configuration and certificate review
- Content Security Policy evaluation
- Third-party component vulnerability analysis
Our Testing Approach
Scoping & Rules of Engagement
Define test scope, target URLs, test accounts, IP whitelisting requirements, and blackout periods. Agree on testing mode (black/grey/white-box) and notification protocols.
Reconnaissance & Mapping
Map the application surface: enumerate endpoints, parameters, authentication mechanisms, and third-party integrations using passive and active reconnaissance techniques.
Automated Baseline Scanning
Run calibrated automated scans (Burp Suite Pro, OWASP ZAP, Nikto) to establish a vulnerability baseline and identify low-hanging fruit before manual deep-dive.
Manual Exploitation & Logic Testing
Conduct in-depth manual testing across all OWASP WSTG categories — focusing on authentication, authorisation, business logic, and injection vulnerabilities that automated tools miss.
Risk Analysis & CVSS Scoring
Analyse findings for exploitability and business impact. Assign CVSS 3.1 scores and contextual risk ratings (Critical/High/Medium/Low/Informational) based on your environment.
Reporting & Debrief
Deliver a detailed technical report with proof-of-concept evidence and an executive summary. Present findings to your technical and management teams with remediation Q&A.
Free Retest for Critical Findings
After your team remediates critical and high findings, we conduct a complimentary retest to verify the fixes hold and issue a closure certificate for your compliance records.
