<dependency>
    <groupId>org.xwiki.platform</groupId>

</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.xwiki.platform

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-21651, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.xwiki.platform

Analyze the terminal output to locate any version of Xwiki platform distribution war in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.10.18), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.xwiki.platform 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Xwiki platform distribution war, 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

### Impact A user able to attach a file to a page can post a malformed TAR file by manipulating file modification times headers, which when parsed by Tika, could cause a denial of service issue via CPU consumption. ### Patches This vulnerability has been patched in XWiki 14.10.18, 15.5.3 and 15.8 RC1. ### Workarounds The workaround is to download [commons-compress 1.24](https://search.maven.org/remotecontent?filepath=org/apache/commons/commons-compress/1.24.0/commons-compress-1.24.0.jar) and replace the one located in XWiki `WEB-INF/lib/` folder. ### References https://jira.xwiki.org/browse/XCOMMONS-2796 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:security@xwiki.org)
