Apache Shiro before 1.11.0, when used with Spring Boot 2.6+, may allow authentication bypass through a specially crafted HTTP request

CVE-2023-22602

What is CVE-2023-22602?

In specific configurations, an authentication bypass vulnerability exists when integrating Apache Shiro prior to version 1.11.0 with Spring Boot 2.6 or newer. This vulnerability arises from differing pattern-matching strategies, allowing an attacker to exploit the authentication process. The default settings in both frameworks utilize Ant-style pattern matching when versions are below those specified. Users are advised to upgrade to Apache Shiro 1.11.0 or adjust Spring Boot’s settings to ensure security by configuring the 'spring.mvc.pathmatch.matching-strategy' to 'ant_path_matcher'.
