CRITICAL

XWiki Platform's async and display macro allow displaying and interacting with any document in restricted mode

Published April 20, 2023Updated November 8, 2023Source: osv

Summary

### Impact It's possible to display any page you cannot access through the combination of the async and display macro. Steps to reproduce: 1. Enable comments for guests by giving guests comment rights 2. As a guest, create a comment with content ```{{async}}{{display reference="Menu.WebHome" /}}{{/async}}``` 3. Open the comments viewer from the menu (appends ?viewer=comments to the URL) -> the `Menu.WebHome` is displayed while the expectation would be to have an error that the current user is not allowed to see it ### Patches The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8, and 13.10.11. ### Workarounds There is no known workaround. ### References https://jira.xwiki.org/browse/XWIKI-20394 https://jira.xwiki.org/browse/XRENDERING-694 ### 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)
