CVE-2023-22602Network attack vector

Authentication bypass via mismatched request-path interpretation

Published Jan 14, 2023 · Updated Aug 2, 2024

Interpretation conflict in Apache Shiro before 1.11.0 with Spring Boot 2.6 and later allows remote attackers to bypass authentication. Shiro assumes Ant-style URL matching, while Spring Boot 2.6 changes its default request matcher, causing the security and routing layers to interpret a crafted path differently. Exposure requires the Shiro-Spring integration with mismatched strategies; a crafted HTTP request can reach application functionality without required authentication.
