CVE-2023-29507: org.xwiki.platform:xwiki-platform-oldcore makes Incorrect Use of Privileged APIs with DocumentAuthors
First published: Wed Apr 12 2023(Updated: )
### Impact The Document script API returns directly a DocumentAuthors allowing to set any authors to the document, which in consequence can allow subsequent executions of scripts since this author is used for checking rights. Example of such attack: ``` {{velocity}} $doc.setContent('{{velocity}}$xcontext.context.authorReference{{/velocity}}') $doc.authors.setContentAuthor('xwiki:XWiki.superadmin') $doc.getRenderedContent() {{/velocity}} ``` ### Patches The problem has been patched in XWiki 14.10 and 14.4.7 by returning a safe script API. ### Workarounds There no easy workaround apart of upgrading. ### References * https://jira.xwiki.org/browse/XWIKI-20380 * https://github.com/xwiki/xwiki-platform/commit/905cdd7c421dbf8c565557cdc773ab1aa9028f83 ### 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)
