How to Fix CVE-2023-26478

To remediate this vulnerability, upgrade all affected Xwiki platform store filesystem 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-store-filesystem-oldcore fixed: 14.4.6 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-store-filesystem-oldcore</artifactId>
    <version>14.4.6</version>
</dependency>
org.xwiki.platform:xwiki-platform-store-filesystem-oldcore fixed: 14.9-rc-1 
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-store-filesystem-oldcore</artifactId>
    <version>14.9-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-2023-26478, 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 store filesystem oldcore in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.4.6), 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-749: Exposed Dangerous Method or Function, where the product provides an applications programming interface (api) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted. In Xwiki platform store filesystem 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 `org.xwiki.store.script.TemporaryAttachmentsScriptService#uploadTemporaryAttachment` is returning an instance of `com.xpn.xwiki.doc.XWikiAttachment`. This class is not supported to be exposed to users without the `programing` right. `com.xpn.xwiki.api.Attachment` should be used instead and takes case of checking the user's rights before performing dangerous operations. ### Patches This has been patched in the version 14.9-rc-1 and 14.4.6. ### Workarounds There's no workaround for this issue. ### References https://jira.xwiki.org/browse/XWIKI-20180 ### For more information If you have any questions or comments about this advisory: * Open an issue in [JIRA](https://jira.xwiki.org/) * Email us at [security ML](mailto:security@xwiki.org)
