How to Fix CVE-2022-36092

To remediate this vulnerability, upgrade all affected Xwiki platform oldcore 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-oldcore fixed: 13.10.4 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-oldcore</artifactId>
    <version>13.10.4</version>
</dependency>
org.xwiki.platform:xwiki-platform-oldcore fixed: 14.2 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-oldcore</artifactId>
    <version>14.2</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-2022-36092, 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 oldcore in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.4), 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-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Xwiki platform oldcore, 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 All rights checks that would normally prevent a user from viewing a document on a wiki can be bypassed using the login action and directly specified templates. This exposes title, content and comments of any document and properties of objects (class and property name must be known, though). This is also exploitable on [private wikis](https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Access%20Rights/#HPrivateWiki). ### Patches This has been patched in versions 14.2 and 13.10.4 by properly checking view rights before loading documents and disallowing non-default templates in the login, registration and skin action. ### Workarounds It would be possible to protect all templates individually by adding code to check access rights first, but due to the number of templates and the fact that some of them need to be used without view rights, this seems impractical. ### References * https://jira.xwiki.org/browse/XWIKI-19549 * https://jira.xwiki.org/browse/XWIKI-18602 ### 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.com)
