How to Fix CVE-2023-29515

To remediate this vulnerability, upgrade all affected Xwiki platform appwithinminutes 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-appwithinminutes fixed: 4.2-milestone-1

</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-2023-29515, 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 appwithinminutes in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2-milestone-1), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Xwiki platform appwithinminutes, 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 who can create a space can become admin of that space through App Within Minutes. The admin right implies the script right and thus allows JavaScript injection. The vulnerability can be exploited by creating an app in App Within Minutes. If the button should be disabled because the user doesn't have global edit right, the app can also be created by directly opening `/xwiki/bin/view/AppWithinMinutes/CreateApplication?wizard=true` on the XWiki installation. ### Patches This has been patched in XWiki 13.10.11, 14.4.8, 14.10.1 and 15.0 RC1 by not granting the space admin right if the user doesn't have script right on the space where the app is created. Error message are displayed to warn the user that the app will be broken in this case. Users who became space admin through this vulnerability won't loose the space admin right due to the fix, so it is advised to check if all users who created AWM apps should keep their space admin rights. ### Workarounds The patch can be applied by patching the affected wiki documents, the most important one being `AppWithinMinutes.LiveTableEditSheet`. Further, the attack can be prevented by denying view access to `AppWithinMinutes.LiveTableEditSheet`. This only impacts creation and editing of App Within Minutes apps. ### References * https://jira.xwiki.org/browse/XWIKI-20190 * https://github.com/xwiki/xwiki-platform/commit/e73b890623efa604adc484ad82f37e31596fe1a6 ### 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)
