How to Fix CVE-2023-34035

To remediate this vulnerability, upgrade all affected Spring Framework 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.springframework.security:spring-security-config fixed: 5.8.5 
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>5.8.5</version>
</dependency>
org.springframework.security:spring-security-config fixed: 6.0.5 
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>6.0.5</version>
</dependency>
org.springframework.security:spring-security-config fixed: 6.1.2 
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>6.1.2</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.springframework.security

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-34035, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.springframework.security

Analyze the terminal output to locate any version of Spring Framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.8.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.springframework.security 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Spring Framework, 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

Spring Security versions 5.8 prior to 5.8.5, 6.0 prior to 6.0.5, and 6.1 prior to 6.1.2 could be susceptible to authorization rule misconfiguration if the application uses requestMatchers(String) and multiple servlets, one of them being Spring MVC’s DispatcherServlet. (DispatcherServlet is a Spring MVC component that maps HTTP endpoints to methods on @Controller-annotated classes.) Specifically, an application is vulnerable when all of the following are true: * Spring MVC is on the classpath * Spring Security is securing more than one servlet in a single application (one of them being Spring MVC’s DispatcherServlet) * The application uses requestMatchers(String) to refer to endpoints that are not Spring MVC endpoints An application is not vulnerable if any of the following is true: * The application does not have Spring MVC on the classpath * The application secures no servlets other than Spring MVC’s DispatcherServlet * The application uses requestMatchers(String) only for Spring MVC endpoints
