Summary
Istio is an open platform to connect, manage, and secure microservices. In affected versions the Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted message which results in the control plane crashing when the validating webhook for a cluster is exposed publicly. This endpoint is served over TLS port 15017, but does not require any authentication from the attacker. For simple installations, Istiod is typically only reachable from within the cluster, limiting the blast radius. However, for some deployments, especially [external istiod](https://istio.io/latest/docs/setup/install/external-controlplane/) topologies, this port is exposed over the public internet. This issue has been patched in versions 1.13.2, 1.12.5 and 1.11.8. Users are advised to upgrade. Users unable to upgrade should disable access to a validating webhook that is exposed to the public internet or restrict the set of IP addresses that can query it to a set of known, trusted entities.

         value: "Istio es una plataforma abierta para conectar, administrar y asegurar microservicios. En las versiones afectadas, el plano de control de Istio, istiod, es vulnerable a un error de procesamiento de peticiones, permitiendo a un atacante malicioso que envíe un mensaje especialmente diseñado que resulte en el bloqueo del plano de control cuando el webhook de comprobación de un clúster se exponga públicamente. Este endpoint es servido a través del puerto 15017 de TLS, pero no requiere ninguna autenticación por parte del atacante. Para instalaciones sencillas, Istiod normalmente sólo es accesible desde dentro del clúster, limitando el radio de explosión. Sin embargo, para algunos despliegues, especialmente las topologías de [istiod externo](https://istio.io/latest/docs/setup/install/external-controlplane/), este puerto está expuesto a través de la Internet pública. Este problema ha sido parcheado en las versiones 1.13.2, 1.12.5 y 1.11.8. Es recomendado a usuarios actualizar. Los usuarios que no puedan actualizarse deben deshabilitar el acceso a un webhook de comprobación que esté expuesto a la Internet pública o restringir el conjunto de direcciones IP que pueden consultarlo a un conjunto de entidades conocidas y confiables",
