SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of identifying and validating authorization vulnerabilities, such as vertical and horizontal privilege escalation, which are often missed during standard security assessments.

Core Features & Use Cases

  • Vulnerability Discovery: Systematically identifies high-risk areas like admin dashboards, multi-tenant isolation, and SSO/SAML integrations.
  • Exploitation Patterns: Provides structured techniques for testing RBAC bypass, parameter pollution, and API gateway misconfigurations.
  • Use Case: When auditing a multi-tenant SaaS application, use this Skill to verify if a standard user can access another tenant's data by manipulating tenant_id parameters or bypassing API authorization middleware.

Quick Start

Use the pentest-access-control skill to audit the current API endpoint for potential vertical privilege escalation vulnerabilities.

FAQPage Schema
How do I test for vertical and horizontal privilege escalation in web applications?▼

Testing for privilege escalation involves systematically probing authorization logic across user roles and administrative endpoints to identify RBAC bypass flaws. It validates whether standard users can manipulate parameters to access restricted admin dashboards or another tenant's data.

What is an RBAC bypass and how does parameter pollution affect API security?▼

An RBAC bypass occurs when authorization middleware fails to enforce role-based access controls. Parameter pollution exploits this by manipulating variables like tenant_id in API requests, allowing attackers to bypass API gateway misconfigurations and access unauthorized multi-tenant data.

How do I audit multi-tenant SaaS applications for tenant isolation vulnerabilities?▼

Auditing multi-tenant SaaS isolation involves testing if standard users can access another tenant's data by manipulating tenant_id parameters. It systematically validates API authorization middleware to ensure secure access enforcement across different tenant boundaries.

How does authentication token manipulation impact SSO and SAML integrations?▼

Authentication token manipulation targets SSO and SAML integrations to bypass access enforcement. It systematically tests authorization logic across user roles to identify high-risk areas where token vulnerabilities allow privilege escalation within web applications.

Can this Skill validate API gateway misconfigurations and authorization middleware?▼

This Skill validates API gateway misconfigurations by systematically testing authorization middleware for RBAC bypass and parameter pollution vulnerabilities. It targets API architectures to ensure secure access enforcement across user roles and administrative endpoints.
