How to Fix CVE-2023-22602

To remediate this vulnerability, upgrade all affected Shiro root dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.shiro:shiro-root fixed: 1.11.0 
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-root</artifactId>
    <version>1.11.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.shiro

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-22602, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.shiro

Analyze the terminal output to locate any version of Shiro root in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.shiro command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-436: Interpretation Conflict, where product a handles inputs or steps differently than product b, which causes a to perform incorrect actions based on its perception of b's state. In Shiro root, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

When using Apache Shiro before 1.11.0 together with Spring Boot 2.6+, a specially crafted HTTP request may cause an authentication bypass. The authentication bypass occurs when Shiro and Spring Boot are using different pattern-matching techniques. Both Shiro and Spring Boot < 2.6 default to Ant style pattern matching. Mitigation: Update to Apache Shiro 1.11.0, or set the following Spring Boot configuration value: `spring.mvc.pathmatch.matching-strategy = ant_path_matcher`
