mukul975/anthro…y-skills

Tests web applications for reflected, stored, and DOM-based Cross-Site Scripting by injecting JavaScript payloads with Burp Suite (XSS extensions, Active Scan++) and browser tools, then bypassing sanitization and CSP to demonstrate session hijacking and user impersonation. Use for OWASP WSTG client-side injection testing or when evaluating input sanitization and output encoding coverage.

Testing for XSS Vulnerabilities

When to Use

  • Testing web applications for client-side injection vulnerabilities as part of OWASP WSTG testing
  • Evaluating the effectiveness of input sanitization and output encoding across all application features
  • Assessing the protection provided by Content Security Policy (CSP) headers against XSS exploitation
  • Demonstrating the impact of XSS through session hijacking, credential theft, or phishing overlay to stakeholders
  • Testing single-page applications (React, Angular, Vue) for DOM-based XSS in client-side routing and rendering

Do not use against applications without written authorization, for deploying persistent XSS payloads that affect real users, or for exfiltrating actual user session tokens from production environments.

Prerequisites

  • Authorized scope defining the target web application and acceptable testing activities
  • Burp Suite Professional with XSS-focused extensions (XSS Validator, Reflector, Active Scan++)
  • Browser with developer tools and XSS testing extensions (HackBar, XSS Hunter)
  • XSS Hunter or Burp Collaborator for out-of-band payload verification
  • SecLists XSS payload lists and custom payloads for WAF bypass scenarios

The tester uses Burp Suite as the primary interception proxy alongside manual testing techniques to find flaws that automated scanners miss. Activates for requests involving web app pentest, OWASP testing, application security assessment, or web vulnerability testing.测试与安全668conducting-api-security-testingmukul975/anthro…y-skillsConducts security testing of REST, GraphQL, and gRPC APIs to identify vulnerabilities in authentication, authorization, rate limiting, input validation, and business logic. The tester uses the OWASP API Security Top 10 as the testing framework, combining Burp Suite interception with Postman collections and custom scripts to test endpoint security at every privilege level. Activates for requests involving API security testing, REST API pentest, GraphQL security assessment, or API vulnerability testing.测试与安全655
