SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents wasted effort by helping you quickly classify an injection vulnerability based on how attacker-controlled input reaches a dangerous interpreter or execution environment.

Core Features & Use Cases

  • Injection sink-based routing: Decide whether the issue is primarily browser, database, template engine, server-side requests, XML parsing, system commands, or NoSQL driven.
  • Fast triage with a decision tree: Use the ingestion point and the sink to select the most accurate deep-topic skill instead of guessing.
  • Covers common and “extra” injection families: Includes a dedicated map for mainstream injection types plus less common categories like SSI, LDAP, XPath, and LaTeX-related injection.

Quick Start

Ask the AI to determine the injection sink for the vulnerability you found, then recommend the single best matching skill from the map.

FAQPage Schema
How do I classify an injection vulnerability during security triage?

Classifying an injection vulnerability involves determining where attacker-controlled input reaches a dangerous interpreter, using sink-focused routing logic to distinguish between browser, database, template engine, or system command execution environments.

What is the best way to route web security injection flaws to the right exploit workflow?

The best way to route web security injection flaws is using a decision tree based on the ingestion point and the sink to select the most accurate deep-topic skill, preventing wasted effort by avoiding guessing between injection families.

How does sink-focused routing logic work for payload classification?

Sink-focused routing logic for payload classification works by mapping how attacker-controlled input reaches a dangerous interpreter, routing the vulnerability to the correct workflow based on whether the sink is browser, database, server-side requests, or XML parsing.

Does this injection triage process cover less common attack surface analysis categories like SSI and LDAP?

Yes, this injection triage process covers attack surface analysis for less common categories including SSI, LDAP, XPath, and LaTeX-related injection, alongside mainstream types like XSS, SQLi, SSRF, XXE, SSTI, and command injection.

Can I use this decision tree to distinguish between NoSQL injection and SQLi vulnerabilities?

Yes, you can use the decision tree to distinguish between NoSQL injection and SQLi by analyzing how attacker-controlled input reaches the dangerous interpreter, routing database-driven flaws to the correct deep-topic skill based on the specific sink.
