How to Fix CVE-2022-41936

To remediate this vulnerability, upgrade all affected Xwiki platform rest server 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-rest-server fixed: 13.10.8 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-rest-server</artifactId>
    <version>13.10.8</version>
</dependency>
org.xwiki.platform:xwiki-platform-rest-server fixed: 14.4.3 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-rest-server</artifactId>
    <version>14.4.3</version>

<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-rest-server</artifactId>
    <version>14.6</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-2022-41936, 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 rest server 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-359: Exposure of Private Personal Information to an Unauthorized Actor, where the product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected. In Xwiki platform rest server, 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 The `modifications` rest endpoint does not filter out entries according to the user's rights. Therefore, information hidden from unauthorized users are exposed though the `modifications` rest endpoint (e.g., comments, page names...). ### Patches Users should upgrade to XWiki 14.6+, 14.4.3+, or13.10.8+. Older versions have not been patched. ### Workarounds No known workaround. ### References - Patch: https://github.com/xwiki/xwiki-platform/commit/38dc1aa1a4435f24d58f5b8e4566cbcb0971f8ff - Jira issue: https://jira.xwiki.org/browse/XWIKI-19997 ### 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)
