How to Fix CVE-2024-29371

To remediate this vulnerability, upgrade all affected Jose4j 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.bitbucket.b_c:jose4j fixed: 0.9.6 
<dependency>
    <groupId>org.bitbucket.b_c</groupId>
    <artifactId>jose4j</artifactId>
    <version>0.9.6</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.bitbucket.b_c

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-29371, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.bitbucket.b_c

Analyze the terminal output to locate any version of Jose4j in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.6), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.bitbucket.b_c 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-1259: Improper Restriction of Security Token Assignment, where the system-on-a-chip (soc) implements a security token mechanism to differentiate what actions are allowed or disallowed when a transaction originates from an entity. however, the security tokens are improperly protected. In Jose4j, 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

In jose4j before 0.9.6, an attacker can cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression.
