SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Authentication flaw detection helps you identify insecure authentication practices such as weak passwords, broken login flows, and bypass vectors before attackers exploit them.

Core Features & Use Cases

  • Detects weak password policies, insecure storage, and bypass vectors across web apps and APIs.
  • Identifies missing brute-force protection, session handling flaws, and credential stuffing risks.
  • Provides guidance and remediation examples to harden authentication mechanisms in real-world projects.

Quick Start

Run the sc-auth skill against your web applications to identify weaknesses in login flows, password handling, and session management.

FAQPage Schema
How do I detect authentication vulnerabilities in web applications and APIs?

Authentication vulnerability detection identifies insecure practices like weak passwords, broken login flows, and bypass vectors across web apps and APIs. It scans production or staging environments to expose weak hashing, missing brute-force protection, hardcoded credentials, and timing-attack risks before attackers exploit them.

What are common login flow bypass vectors and how can I identify them?

Login flow bypass vectors include broken session management, credential stuffing risks, and hardcoded credentials. You can identify them by running targeted authentication flaw detection against your login mechanisms to pinpoint missing brute-force protection and insecure session handling.

How do I check my password storage for weak hashing vulnerabilities?

Checking password storage for weak hashing involves analyzing your authentication mechanisms to detect insecure storage practices. Authentication flaw detection identifies weak hashing implementations and provides remediation examples to harden password storage in real-world projects.

Can I test MFA and session management flaws in staging environments?

Yes, you can test MFA and session management flaws in staging environments. The detection process applies to login flows, MFA, and session management across both production and staging environments to identify authentication vulnerabilities and bypass vectors.

Why do generic error messages create timing-attack risks in authentication?

Generic error messages create timing-attack risks by allowing attackers to differentiate between valid and invalid usernames based on response times. Authentication flaw detection enforces the identification of these generic error messages alongside missing brute-force protection to prevent credential enumeration.
