How to Fix CVE-2023-29522
To remediate this vulnerability, upgrade all affected Xwiki platform xclass 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.
<dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-xclass-ui</artifactId>
<version>14.4.8</version>
</dependency><dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-xclass-ui</artifactId>
<version>14.10.3</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.xwiki.platformHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-29522, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.platformAnalyze the terminal output to locate any version of Xwiki platform xclass ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.4.8), 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Xwiki platform xclass 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.

"details" : "### Impact\n\nAny user with view rights can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. The attack works by opening a non-existing page with a name crafted to contain a dangerous payload.\n\nFor instance: `Open <xwiki-host>/xwiki/bin/view/%22%2F%7D%7D%7B%7B%2Fhtml%7D%7D%20%7B%7Basync%20async%3D%22true%22%20cached%3D%22false%22%20context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln(%22Hello%20%22%20%2B%20%22from%20groovy!%22)%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D?sheet=XWiki.ClassSheet&xpage=view`, where `<xwiki-host>` is the URL of your XWiki installation.\n\n### Patches\nThis has been patched in XWiki 14.4.8, 14.10.3 and 15.0RC1.\n\n### Workarounds\nThe fix is only impacting Velocity templates and page contents, so applying this [patch](https://github.com/xwiki/xwiki-platform/commit/d7e56185376641ee5d66477c6b2791ca8e85cfee) is enough to fix the issue.\n\n### References\n- https://github.com/xwiki/xwiki-platform/commit/d7e56185376641ee5d66477c6b2791ca8e85cfee\n- https://jira.xwiki.org/browse/XWIKI-20456\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Open an issue in [Jira XWiki.org](https://jira.xwiki.org/)\n- Email us at [Security Mailing List](mailto:security@xwiki.org)",
