Descriptions

XWiki Platform is a generic wiki platform. Starting in version 3.0.1 and prior to versions 4.10.20, 15.5.4, and 15.10-rc-1, remote code execution is possible via PDF export templates. This vulnerability has been patched in XWiki 14.10.20, 15.5.4 and 15.10-rc-1. If PDF templates are not typically used on the instance, an administrator can create the document `XWiki.PDFClass` and block its edition, after making sure that it does not contain a `style` attribute. Otherwise, there are no known workarounds aside from upgrading.

XWiki Platform es una plataforma wiki genérica. A partir de la versión 3.0.1 y anteriores a las versiones 4.10.20, 15.5.4 y 15.10-rc-1, la ejecución remota de código es posible mediante plantillas de exportación de PDF. Esta vulnerabilidad ha sido parcheada en XWiki 14.10.20, 15.5.4 y 15.10-rc-1. Si las plantillas PDF no se utilizan normalmente en la instancia, un administrador puede crear el documento "XWiki.PDFClass" y bloquear su edición, después de asegurarse de que no contiene un atributo "estilo". De lo contrario, no se conocen workarounds aparte de la actualización.
