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-2023-29521, 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 vfs ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.11), 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Xwiki platform vfs ui, 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 Any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of `Macro.VFSTreeMacro`. This page is not installed by default. See https://jira.xwiki.org/browse/XWIKI-20260 for the reproduction steps. ### Patches The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.2, 14.4.8, 13.10.11. ### Workarounds The issue can be fixed by applying this [patch](https://github.com/xwiki/xwiki-platform/commit/fad02328f5ec7ab7fe5b932ffb5bc5c1ba7a5b12) on `Macro.VFSTreeMacro`. ### References - https://jira.xwiki.org/browse/XWIKI-20260 - https://github.com/xwiki/xwiki-platform/commit/fad02328f5ec7ab7fe5b932ffb5bc5c1ba7a5b12 ### 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)
