web2-vuln-classes

Web vulnerabilities like XSS and SQL injection stem from improper input validation and unescaped output. This reference explains the root causes for 20 bug classes, detailing how insecure coding practices allow attackers to inject malicious payloads into web applications.

Testing for IDOR involves manipulating object references in API endpoints or URLs to access unauthorized data. This guide provides detection patterns and sample payloads to identify insecure direct object reference flaws by systematically altering identifiers during security auditing.

The web2 vulnerability classes covered include IDOR, XSS, SSRF, SQLi, and 16 other bug types. This reference summarizes each class, explaining their mechanisms, detection techniques, and exploitation methods to support comprehensive security auditing and testing.

Detecting SSRF vulnerabilities uses sample payloads that trick the server into making requests to internal resources or metadata endpoints. This guide offers testing checklists and specific payloads to identify server-side request forgery by targeting URL parameters and input vectors.

This reference provides mitigation steps for secure software development across various bug classes. It details practical testing patterns and explains how understanding root causes and exploitation techniques informs defensive coding practices for web applications.
