How to Fix CVE-2023-29203

To remediate this vulnerability, upgrade all affected Xwiki platform web templates 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-web-templates fixed: 13.10.8
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web-templates</artifactId>

    <artifactId>xwiki-platform-web-templates</artifactId>
    <version>14.7-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-2023-29203, 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 web templates in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.8), 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Xwiki platform web templates, 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 It's possible to list some users who are normally not viewable from subwiki by requesting users on a subwiki which allows only global users with `uorgsuggest.vm`. This issue only concerns hidden users from main wiki. Note that the disclosed information are the username and the first and last name of users, no other information is leaked. ### Patches The problem has been patched on XWiki 13.10.8, 14.4.3 and 14.7RC1. ### Workarounds It's possible to workaround this vulnerability by patching directly `uorgsuggest.vm ` to apply the same changes as in https://github.com/xwiki/xwiki-platform/pull/1883. ### References * JIRA ticket: https://jira.xwiki.org/browse/XWIKI-20007 * this vulnerability is actually a remaining of https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-97jg-43c9-q6pf which wasn't entirely fixed back then ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](https://jira.xwiki.org) * Email us at [security ML](mailto:security@xwiki.org)
