SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

The WooYun methodology helps security practitioners identify and prioritize business-logic vulnerabilities that scanners often miss, enabling more effective audits and risk reduction.

Core Features & Use Cases

  • Domain-driven vulnerability framework across authentication, authorization, finance, information, logic flow, and configuration.
  • Practical testing guides, field-tested patterns, and remediation-oriented strategies drawn from WooYun cases.
  • Use cases include validating multi-step processes, IDOR/privilege escalation, and financial logic security in web apps and APIs.

Quick Start

Start by mapping a target's business processes and applying domain-specific patterns to uncover logic flaws and verify fixes.

FAQPage Schema
How do I test for business-logic vulnerabilities in web applications?▼

Testing for business-logic vulnerabilities involves mapping application workflows and applying domain-specific attack patterns to bypass business rules across authentication, authorization, and financial domains.

What is a business-logic vulnerability and how do scanners miss them?▼

A business-logic vulnerability is a design flaw where application rules can be bypassed. Automated scanners often miss them because they require manual workflow mapping to evaluate logic flaws.

How can I identify IDOR and privilege escalation vulnerabilities during a security audit?▼

Identify IDOR and privilege escalation vulnerabilities by mapping business processes and applying domain-specific patterns to evaluate authorization bypasses, documenting evidence and remediation steps.

Does manual pentesting work for finding financial logic flaws in APIs?▼

Manual pentesting works for financial logic flaws in APIs by validating multi-step processes and applying field-tested attack patterns to assess risk and verify fixes.

What are the limitations of automated security audits for logic-flow vulnerabilities?▼

Automated security audits for logic-flow vulnerabilities are limited because they cannot map complex business workflows or understand context, requiring manual testing to uncover bypasses and assess configuration risks.
