How to Fix CVE-2022-41928

To remediate this vulnerability, upgrade all affected Xwiki platform attachment ui 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-attachment-ui fixed: 13.10.7
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-attachment-ui</artifactId>
    <version>13.10.7</version>
</dependency>
org.xwiki.platform:xwiki-platform-attachment-ui fixed: 14.4.2
<dependency>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-attachment-ui</artifactId>
    <version>14.4.2</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-2022-41928, 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 attachment ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.10.7), 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-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection'), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). In Xwiki platform attachment ui, 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 the right to edit his personal page can follow one of the scenario below: **Scenario 1**: - Log in as a simple user with just edit rights on the user profile - Go to the user's profile - Upload an attachment in the attachment tab at the bottom of the page (any image is fine) - Click on "rename" in the attachment list and enter `{{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/async}}.png` as new attachment name and submit the rename - Go back to the user profile - Click on the edit icon on the user avatar - `Hello from groovy!` is displayed as the title of the attachment **Scenario 2**: - Log in as a simple user with just edit rights on a page - Create a Page `MyPage.WebHome` - Create an XClass field of type String named `avatar` - Add an XObject of type `MyPage.WebHome` on the page - Insert an `attachmentSelector` macro in the document with the following values: - **classname**: `MyPage.WebHome` - **property**: `avatar` - **savemode**: `direct` - **displayImage**: `true` - **width**: `]] {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("Hello from groovy!"){{/groovy}}{{/async}}`. You'll find below a snippet of an `attachmentSelector` macro declaration. - Display the page - Use the attachment picker to select an image - `Hello from groovy` is displayed aside the image Example of an `attachmentSelector` macro declaration: ``` `{{attachmentSelector classname="MyPage.WebHome" property="avatar" savemode="direct" displayImage="true" width="]] {{async async=~"true~" cached=~"false~" context=~"doc.reference~"~}~}{{groovy~}~}println(~"Hello from groovy!~"){{/groovy~}~}{{/async~}~}"/}}` ``` **Note**: The issue can also be reproduced by inserting the dangerous payload in the `height` or `alt` macro properties. ### Patches The issue can be fixed on a running wiki by updating `XWiki.AttachmentSelector` with the versions below: - 14.5-rc-1+: https://github.com/xwiki/xwiki-platform/commit/eb15147adf94bddb92626f862c1710d45bcd64a7#diff-e1513599ab698991f6cbba55d38f3f464432ced8d137a668b1f7618c7e747e23 - 14.4.2+: https://github.com/xwiki/xwiki-platform/commit/c02f8eb1f3c953d124f2c097021536f8bc00fa8d#diff-e1513599ab698991f6cbba55d38f3f464432ced8d137a668b1f7618c7e747e23 - 13.10.7+: https://github.com/xwiki/xwiki-platform/commit/efd0df0468d46149ba68b66660b93f31b6318515#diff-e1513599ab698991f6cbba55d38f3f464432ced8d137a668b1f7618c7e747e23 ### Workarounds No known workaround. ### References - https://jira.xwiki.org/browse/XWIKI-19800 ### 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)
