How to Fix CVE-2022-41934

To remediate this vulnerability, upgrade all affected Xwiki platform menu ui 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-menu-ui fixed: 13.10.8
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-menu-ui</artifactId>
    <version>13.10.8</version>
</dependency>
org.xwiki.platform:xwiki-platform-menu-ui fixed: 14.4.3
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-menu-ui</artifactId>
    <version>14.4.3</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-2022-41934, 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 menu ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.8), 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-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. In Xwiki platform menu 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 on commonly accessible documents including the menu macro can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation due to improper escaping of the macro content and parameters of the menu macro. The issue can be demonstrated by opening `<server>/xwiki/bin/view/Main?sheet=CKEditor.HTMLConverter&language=en&sourceSyntax=xwiki%2F2.1&stripHTMLEnvelope=true&fromHTML=false&toHTML=true&text=%7B%7Bmenu%7D%7D%7B%7Bcache+id%3D%22menuMacro%22%7D%7D%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+Groovy%21%22%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fcache%7D%7D%7B%7B%2Fmenu%7D%7D` where `<server>` is the URL of the XWiki installation. If this displays "Hello from Groovy!", the installation is vulnerable. ### Patches The problem has been patched in XWiki 14.6RC1, 13.10.8 and 14.4.3. ### Workarounds The [patch](https://github.com/xwiki/xwiki-platform/commit/2fc20891e6c6b0ca05ee07e315e7f435e8919f8d) for the document `Menu.MenuMacro` can be manually applied or a XAR archive of a patched version can be [imported](https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/Imports#HImportingXWikipages). The menu macro was basically unchanged since XWiki 11.6 so on XWiki 11.6 or later the [patch for version of 13.10.8](https://github.com/xwiki/xwiki-platform/commit/59ccca24a8465a19f40c51d65fcc2c09c1edea16) can most likely be applied, on XWiki version 14.0 and later the versions in XWiki 14.6 and 14.4.3 should be appropriate. ### References * https://github.com/xwiki/xwiki-platform/commit/2fc20891e6c6b0ca05ee07e315e7f435e8919f8d * https://jira.xwiki.org/browse/XWIKI-19857 ### 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)
