SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Injection vulnerabilities arise when user input flows unvalidated into executable contexts, enabling attackers to leak data, deface applications, or take over systems. This Skill provides a structured checklist and orchestration to systematically test multiple sink types across inputs and endpoints.

Core Features & Use Cases

  • Systematic sink-based injection testing: SQL, XSS, command injection, SSRF, XXE, SSTI across forms, query params, and API payloads.
  • Multi-skill orchestration: loads and runs relevant sub-skills for each sink type to verify vulnerabilities end-to-end.
  • Real-world use case: Security tester schedules automated injections against a web app, collects evidence, and generates a remediation plan.

FAQPage Schema
How do I systematically test injection vulnerabilities across web application endpoints?

Systematic injection testing identifies and verifies vulnerabilities across sinks like SQL, XSS, command injection, SSRF, XXE, and SSTI by orchestrating targeted scans against forms, query parameters, and API payloads to generate structured findings reports.

Can I test multiple injection sink types like SQL injection and XSS in a single automated scan?

Yes, you can test multiple injection sink types in a single scan. The tool orchestrates relevant sub-skills for each sink type, including SQL injection, XSS, command injection, SSRF, XXE, and SSTI, to verify vulnerabilities end-to-end across application inputs.

Do I need bash and rg utilities to run injection vulnerability tests on APIs?

Yes, you need bash, rg, and related utilities installed in your environment to perform injection vulnerability scans. These dependencies are required to execute the systematic tests across web applications, APIs, and microservices and output actionable mitigation reports.

What is the best way to generate a remediation plan after finding SSRF or XXE vulnerabilities?

The best way to generate a remediation plan is to run an orchestrated injection test that collects evidence across sinks like SSRF and XXE. The tool outputs a structured findings report with actionable mitigations tailored to the discovered vulnerabilities.

Does this injection testing approach work for microservices and API payloads as well as web forms?

Yes, this injection testing approach works for microservices and API payloads. It systematically tests application inputs across web forms, query parameters, and API payloads to identify executable context vulnerabilities like SQL injection, XSS, and SSTI.
