How to Fix CVE-2023-26473

To remediate this vulnerability, upgrade all affected Xwiki platform web 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-web fixed: 13.10.11
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web</artifactId>
    <version>13.10.11</version>
</dependency>
org.xwiki.platform:xwiki-platform-web fixed: 14.4.7

    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-web</artifactId>
    <version>14.10</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-2023-26473, 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 web in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.11), 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Xwiki platform web, 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 edit right can execute arbitrary database select and access data stored in the database. To reproduce: * In admin, rights, remove scripting rights for {{XWikiAllGroup}}. * Create a new user without any special privileges. * Create a page "Private.WebHome" with {{TOKEN_42}} as content. Go to "page administration" and explicitly set all rights for "Admin" to remove them for all other users. * Logout and login as the unprivileged user. Ensure that the previously created page cannot be viewed. * Create a new page "ExploitClass.WebHome" and then open it in the class editor (first, make the user an advanced user). * Add a field named {{ContentList}} of type {{Database List}} * Enter in field "Hibernate Query" the following content: {noformat}select doc.content, doc.fullName from XWikiDocument as doc where doc.fullName = 'Private.WebHome'{noformat} * Save the class. * Open [http://localhost:8080/xwiki/bin/view/ExploitClass/?xpage=suggest&classname=ExploitClass.WebHome&fieldname=ContentList&firCol=doc.fullName&secCol=-] ### Patches The problem has been patched on XWiki 13.10.11, 14.4.7, and 14.10. ### Workarounds There is no workaround for this vulnerability other than upgrading. ### References https://jira.xwiki.org/browse/XWIKI-19523 ### 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)
