How to Fix CVE-2024-31997

To remediate this vulnerability, upgrade all affected Xwiki platform uiextension api 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.xwiki.platform:xwiki-platform-uiextension-api fixed: 14.10.19
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-uiextension-api</artifactId>

</dependency>
org.xwiki.platform:xwiki-platform-uiextension-api fixed: 15.5.4

    <artifactId>xwiki-platform-uiextension-api</artifactId>
    <version>15.9-rc-1</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.xwiki.platform

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-31997, 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 uiextension api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.10.19), 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Xwiki platform uiextension api, 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 Parameters of UI extensions are always interpreted as Velocity code and executed with programming rights. Any user with edit right on any document like the user's own profile can create UI extensions. This allows remote code execution and thereby impacts the confidentiality, integrity and availability of the whole XWiki installation. To reproduce, edit your user profile with the object editor and add a UIExtension object with the following values: ``` Extension Point ID: org.xwiki.platform.panels.Applications Extension ID: platform.panels.myFakeApplication Extension parameters:  label=I got programming right: $services.security.authorization.hasAccess('programming') target=Main.WebHome targetQueryString= icon=icon:bomb Extension Scope: "Current User". ``` Save the document and open any document. If an application entry with the text "I got programming right: true" is displayed, the attack succeeded, if the code in "label" is displayed literally, the XWiki installation isn't vulnerable. ### Patches This vulnerability has been patched in XWiki 14.10.19, 15.5.4 and 15.9-RC1. ### Workarounds We're not aware of any workarounds apart from upgrading. ### References * https://jira.xwiki.org/browse/XWIKI-21335 * https://github.com/xwiki/xwiki-platform/commit/171e7c7d0e56deaa7b3678657ae26ef95379b1ea
