Descriptions

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. `org.xwiki.platform:xwiki-platform-web` starting in version 3.1-milestone-1 and prior to 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` starting in version 2.4-milestone-2 and prior to version 3.1-milestone-1 are vulnerable to cross-site scripting. An attacker can create a template provider on any document that is part of the wiki (could be the attacker's user profile) that contains malicious code. This code is executed when this template provider is selected during document creation which can be triggered by sending the user to a URL. For the attacker, the only requirement is to have an account as by default the own user profile is editable. 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 `org.xwiki.platform:xwiki-platform-web` 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` 14.10.2 and 15.5-rc-1, and `org.xwiki.platform:xwiki-web-standard` 3.1-milestone-1 by adding the 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. `org.xwiki.platform:xwiki-platform-web` a partir de la versión 3.1-milestone-1 y anteriores a 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` anteriores a las versiones 14.10. 2 y 15.5-rc-1, y `org.xwiki.platform:xwiki-web-standard` a partir de la versión 2.4-milestone-2 y anteriores a la versión 3.1-milestone-1 son vulnerables a Cross-Site Scripting (XSS). Un atacante puede crear un proveedor de plantilla en cualquier documento que forme parte de la wiki (podría ser el perfil de usuario del atacante) que contenga código malicioso. Este código se ejecuta cuando se selecciona este proveedor de plantilla durante la creación del documento, lo que se puede activar enviando al usuario a una URL. Para el atacante, el único requisito es tener una cuenta ya que, de forma predeterminada, el perfil de usuario es editable. 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 `org.xwiki.platform:xwiki-platform-web` 13.4-rc-1, `org.xwiki.platform:xwiki-platform-web-templates` 14.10.2 y 15.5-rc-1, y `org.xwiki.platform:xwiki-web-standard` 3.1-milestone-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.
