Descriptions

XWiki Change Request is an XWiki application allowing to request changes on a wiki without publishing directly the changes. Change request allows to edit any page by default, and the changes are then exported in an XML file that anyone can download. So it's possible for an attacker to obtain password hash of users by performing an edit on the user profiles and then downloading the XML file that has been created. This is also true for any document that might contain password field and that a user can view.
This vulnerability impacts all version of Change Request, but the impact depends on the rights that has been set on the wiki since it requires for the user to have the Change request right (allowed by default) and view rights on the page to target. This issue cannot be easily exploited in an automated way. The patch consists in denying to users the right of editing pages that contains a password field with change request. It means that already existing change request for those pages won't be removed by the patch, administrators needs to take care of it. The patch is provided in Change Request 1.10, administrators should upgrade immediately. It's possible to workaround the vulnerability by denying manually the Change request right on some spaces, such as XWiki space which will include any user profile by default.

XWiki Change Request es una aplicación XWiki que permite solicitar cambios en una wiki sin publicar directamente los cambios. Change Request permite editar cualquier página de forma predeterminada y luego los cambios se exportan en un archivo XML que cualquiera puede descargar. Por lo tanto, es posible que un atacante obtenga el hash de contraseña de los usuarios realizando una edición en los perfiles de usuario y luego descargando el archivo XML que se ha creado. Esto también se aplica a cualquier documento que pueda contener un campo de contraseña y que un usuario pueda ver. Esta vulnerabilidad afecta a todas las versiones de Change Request, pero el impacto depende de los derechos que se hayan establecido en el wiki, ya que requiere que el usuario tenga el derecho de Change Request (permitido de forma predeterminada) y derechos de visualización en la página de destino. Este problema no se puede explotar fácilmente de forma automatizada. El parche consiste en negar a los usuarios el derecho de editar páginas que contengan un campo de contraseña con Change Request. Significa que el parche no eliminará las solicitudes de cambio ya existentes para esas páginas, los administradores deben encargarse de ello. El parche se proporciona en la Change Request 1.10; los administradores deben actualizarlo de inmediato. Es posible solucionar la vulnerabilidad denegando manualmente Change Request en algunos espacios, como el espacio XWiki, que incluirá cualquier perfil de usuario de forma predeterminada.
