Details

XWiki Platform vulnerable to persistent Cross-site Scripting through CKEditor Configuration pages ### Effect Any user with edit rights can edit all pages in the `CKEditor' space. This makes it possible to perform a variety of harmful actions, such as - removing technical documents, leading to loss of service - Editing the javascript configuration of CKEditor, leading to persistent XSS ### Patches This issue has been patched in XWiki 14.10.6 and XWiki 15.1. This issue has been patched on the CKEditor Integration extension 1.64.9 for XWiki version older than 14.6RC1. ### Workarounds The issue can be fixed manually by restricting the `edit` and `delete` rights to a trusted user or group (e.g. the `XWiki.XWikiAdminGroup` group), implicitly disabling those rights for all other users. See https://github.com/xwiki/xwiki-platform/commit/9d9d86179457cb8dc48b4491510537878800be4f ### References - https://jira.xwiki.org/browse/XWIKI-20590 - https://jira.xwiki.org/browse/CKEDITOR-508 - https://github.com/xwiki/xwiki-platform/commit/9d9d86179457cb8dc48b4491510537878800be4f ### 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)
