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.
