How to Fix CVE-2022-23615

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: 13.0 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-oldcore</artifactId>
    <version>13.0</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-2022-23615, 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 13.0), 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. 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

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user with SCRIPT right (EDIT right before XWiki 7.4) can save a document with the right of the current user which allow accessing API requiring programming right if the current user has programming right. It has been patched in XWiki 13.0. The only workaround is to give SCRIPT right only to trusted users.
