Systematic Vulnerability Assessment and Security Analysis of Web Applications using Burp Suite

Abstract

Cybersecurity has become one of the most significant concerns in modern computing due to the exponential rise in sophisticated web-based attacks. Web applications routinely process sensitive user information, financial data, and classified business records. Any vulnerability within these applications can lead to unauthorized access, catastrophic data theft, and severe organizational compromise. This comprehensive study focuses on identifying, analyzing, and validating critical web application vulnerabilities using Burp Suite Community Edition. It bridges theoretical cybersecurity concepts with practical, real-world penetration testing methodologies. The practical implementation involves a deep-dive security assessment of a live enterprise portal. The assessment successfully uncovered critical and high-severity flaws, including Unauthenticated API Access, Authentication Bypasses via response manipulation, Insecure Direct Object References (IDOR), Server-Side Request Forgery (SSRF), and Cross-Site Scripting (XSS). By leveraging manual testing techniques alongside Burp Suite's powerful proxy and fuzzing capabilities, this study highlights the critical need for secure coding practices, strict server-side authorization, and continuous manual penetration testing to supplement automated security tools in the Software Development Life Cycle (SDLC).
