How to Fix CVE-2023-46242

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: 14.10.7 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-oldcore</artifactId>
    <version>14.10.7</version>
</dependency>
org.xwiki.platform:xwiki-platform-oldcore fixed: 15.2-rc-1 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-oldcore</artifactId>
    <version>15.2-rc-1</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-2023-46242, 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 14.10.7), 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. 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 In XWiki Platform, it's possible to execute content with the right of any user if you can make this user follow a crafted URL. This is possible because edit action sets and thereby executes the page content without checking for a cross-site request forgert (CSRF) token. To reproduce: Get a user with programming rights to visit the URL `<xwiki-host>/xwiki/bin/edit/Main/?content=%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+Groovy%21%22%29%7B%7B%2Fgroovy%7D%7D&xpage=view`, where `<xwiki-host>` is the URL of your XWiki installation. This can be done by embedding an image with this URL. The text "Hello from Groovy!" is displayed in the page content, showing that the Groovy macro has been executed. ### Patches This has been patched in XWiki 14.10.7 and 15.2-RC-1. ### Workarounds There are no known workarounds for it. ### References * https://jira.xwiki.org/browse/XWIKI-20386 * https://github.com/xwiki/xwiki-platform/commit/cf8eb861998ea423c3645d2e5e974420b0e882be ### 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)
