Descriptions

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.13.0 and prior to versions 1.13.7, 1.14.12, and 1.15.6, the output of `cilium-bugtool` can contain sensitive data when the tool is run (with the `--envoy-dump` flag set) against Cilium deployments with the Envoy proxy enabled. Users of the TLS inspection, Ingress with TLS termination, Gateway API with TLS termination, and Kafka network policies with API key filtering features are affected. The sensitive data includes the CA certificate, certificate chain, and private key used by Cilium HTTP Network Policies, and when using Ingress/Gateway API and the API keys used in Kafka-related network policy. `cilium-bugtool` is a debugging tool that is typically invoked manually and does not run during the normal operation of a Cilium cluster. This issue has been patched in Cilium v1.15.6, v1.14.12, and v1.13.17. There is no workaround to this issue.

Cilium es una solución de redes, observabilidad y seguridad con un plano de datos basado en eBPF. A partir de la versión 1.13.0 y anteriores a las versiones 1.13.7, 1.14.12 y 1.15.6, la salida de `cilium-bugtool` puede contener datos confidenciales cuando se ejecuta la herramienta (con el comando `--envoy-dump` conjunto de indicadores) contra implementaciones de Cilium con el proxy Envoy habilitado. Los usuarios de la inspección TLS, Ingress con terminación TLS, Gateway API con terminación TLS y políticas de red Kafka con funciones de filtrado de claves API se ven afectados. Los datos confidenciales incluyen el certificado de CA, la cadena de certificados y la clave privada utilizadas por las políticas de red HTTP de Cilium y cuando se utiliza la API de Ingress/Gateway y las claves API utilizadas en la política de red relacionada con Kafka. `cilium-bugtool` es una herramienta de depuración que normalmente se invoca manualmente y no se ejecuta durante el funcionamiento normal de un clúster Cilium. Este problema se solucionó en Cilium v1.15.6, v1.14.12 y v1.13.17. No existe workaround para este problema.
