Descriptions

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When document names are validated according to a name strategy (disabled by default), XWiki starting in version 12.0-rc-1 and prior to versions 12.10.12 and 15.5-rc-1 is vulnerable to a reflected cross-site scripting attack in the page creation form. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in XWiki 14.10.12 and 15.5-rc-1 by adding appropriate escaping. The vulnerable template file `createinline.vm` is part of XWiki's WAR and can be patched by manually applying the changes from the fix.

XWiki Platform es una plataforma wiki genérica que ofrece servicios de ejecución para aplicaciones creadas sobre ella. Cuando los nombres de los documentos se validan según una estrategia de nombres (deshabilitada de forma predeterminada), XWiki a partir de la versión 12.0-rc-1 y anteriores a las versiones 12.10.12 y 15.5-rc-1 es vulnerable a un ataque de Cross-Site Scripting (XSS) Reflejado en el formulario de creación de página. Esto permite a un atacante ejecutar acciones arbitrarias con los derechos del usuario que abre el enlace malicioso. Dependiendo de los derechos del usuario, esto puede permitir la ejecución remota de código y acceso completo de lectura y escritura a toda la instalación de XWiki. Esto se ha parcheado en XWiki 14.10.12 y 15.5-rc-1 agregando el escape apropiado. El archivo de plantilla vulnerable `createinline.vm` es parte de WAR de XWiki y se puede parchear aplicando manualmente los cambios de la solución.
