CVE-2023-29207

Description

### Impact The [Livetable Macro](https://extensions.xwiki.org/xwiki/bin/view/Extension/Livetable%20Macro) wasn't properly sanitizing column names, thus allowing the insertion of raw HTML code including JavaScript. This vulnerability was also exploitable via the [Documents Macro](https://extensions.xwiki.org/xwiki/bin/view/Extension/Documents%20Macro) that is included since XWiki 3.5M1 and doesn't require script rights, this can be demonstrated with the syntax `{{documents id="example" count="5" actions="false" columns="doc.title, before<script>alert(1)</script>after"/}}`. Therefore, this can also be exploited by users without script right and in comments. With the interaction of a user with more rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content. ### Patches This has been patched in XWiki 14.9, 14.4.6, and 13.10.10. ### Workarounds It is possible to apply the [patch](https://github.com/xwiki/xwiki-platform/commit/65ca06c51e7a1d5a579344c7272b2cc9a9a21126) to existing installations without upgrading. Only the files `skins/flamingo/macros.vm` and `templates/macros.vm` in the web application directory need to be replaced by a patched version. ### 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)
