Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Apache Shiro < 1.6.0 has an **Authorization Bypass** flaw. π **Consequences**: Attackers can bypass authentication entirely using crafted HTTP requests, gaining unauthorized access to protected resources.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: The vulnerability lies in how Shiro handles specific URL patterns (e.g., trailing semicolons or specific path structures). It fails to enforce security constraints correctly for these edge cases.β¦
π― **Affected**: **Apache Shiro** versions **1.5.3** and earlier (specifically < 1.6.0). π₯οΈ **Environment**: Commonly found in Java/Spring Boot applications using Shiro for security management.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Bypass login screens. Access sensitive data or admin functions without credentials. π **Impact**: Full unauthorized access to resources protected by Shiro's `authc` (authentication) rules.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. No authentication required. βοΈ **Config**: Only requires the target app to use vulnerable Shiro versions.β¦
π₯ **Public Exploit**: **YES**. Multiple PoCs exist on GitHub (e.g., `EXP-Docs`, `0xkami`). π **Wild Exploitation**: High risk. Simple URL manipulation (like `/res/%3bpoc`) triggers the bypass immediately.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: 1. Identify if your app uses Apache Shiro. 2. Check version number (must be < 1.6.0). 3. Test URLs with trailing semicolons (`;`) or specific path injections on protected endpoints. 4.β¦
β‘ **Priority**: **CRITICAL**. π¨ **Reason**: Easy to exploit, no auth needed, affects widely used Java security framework. Immediate patching to v1.6.0+ is strongly recommended.
