SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Session management weaknesses can enable account takeover through fixation, predictable tokens, or insufficient invalidation during logout or password changes, leading to high-security risk.

Core Features & Use Cases

  • Comprehensive session testing: detect session fixation, predictable session IDs, and weak logout invalidation.
  • JWT session evaluation: check for expiry, revocation gaps, and insecure token handling.
  • Practical use cases: verify attacker scenarios involving concurrent sessions and post-authentication session persistence in real-world apps.

Quick Start

Run a targeted assessment of session handling on the target app and document reproducible steps with evidence.

Frequently Asked Questions about hunt-session

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test for session management weaknesses like fixation and weak logout invalidation?▼

JWT session security evaluation checks for expiry gaps, revocation issues, and insecure token handling. Analyze JWT-based sessions across authentication flows to identify vulnerabilities that enable account takeover through concurrent sessions or post-authentication persistence.

What is session fixation and how does it enable account takeover in web apps?▼

Session fixation is a session management weakness where attackers exploit predictable session IDs or insufficient invalidation during logout and password changes. Testing these weaknesses across login flows helps evaluate account takeover risk and communicate findings to stakeholders with reproducible evidence.

How do I evaluate JWT expiry and revocation gaps during vulnerability assessments?▼

Yes, you can assess concurrent sessions and post-authentication persistence by verifying attacker scenarios in real-world web apps. Targeted session handling assessments detect whether session fixation or weak logout invalidation allows unauthorized account access across multiple active sessions.

What's the best way to report session management vulnerabilities to stakeholders?▼

Session management testing covers login flows, logout behavior, password-change handling, and JWT-based sessions. It detects fixation, predictable session IDs, and weak logout invalidation while evaluating concurrent session attacker scenarios and post-authentication persistence in real-world web apps.
