Zope versions prior to versions 4.6.3 and 5.3 have a remote code execution security issue. In order to be affected, one must use Python 3 for one's Zope deployment, run Zope 4 below version 4.6.3 or Zope 5 below version 5.3, and have the optional `Products.PythonScripts` add-on package installed. By default, one must have the admin-level Zope \"Manager\" role to add or edit Script (Python) objects through the web. Only sites that allow untrusted users to add/edit these scripts through the web are at risk. Zope releases 4.6.3 and 5.3 are not vulnerable. As a workaround, a site administrator can restrict adding/editing Script (Python) objects through the web using the standard Zope user/role permission mechanisms. Untrusted users should not be assigned the Zope Manager role and adding/editing these scripts through the web should be restricted to trusted users only. This is the default configuration in Zope." }, { "lang": "es", "value": "Zope es un servidor de aplicaciones web de c\u00f3digo abierto. Zope versiones anteriores a 4.6.3 y 5.3 tienen un problema de seguridad de ejecuci\u00f3n de c\u00f3digo remota . Para ser afectado, uno debe usar Python 3 para su despliegue de Zope, ejecutar Zope 4 por debajo de la versi\u00f3n 4.6.3 o Zope 5 por debajo de la versi\u00f3n 5.3, y tener el paquete adicional opcional \"Products.PythonScripts\" instalado.
