Descriptions

Cilium is open source software for providing and securing network connectivity and loadbalancing between application workloads. Cilium prior to versions 1.9.16, 1.10.11, and 1.11.15 contains an incorrect default permissions vulnerability. Operating Systems with users belonging to the group ID 1000 can access the API of Cilium via Unix domain socket available on the host where Cilium is running. This could allow malicious users to compromise integrity as well as system availability on that host. The problem has been fixed and the patch is available in versions 1.9.16, 1.10.11, and 1.11.5. A potential workaround is to modify Cilium's DaemonSet to run with a certain command, which can be found in the GitHub Security Advisory for this vulnerability.

Cilium es un software de código abierto para proporcionar y asegurar la conectividad de red y el equilibrio de carga entre las cargas de trabajo de las aplicaciones. Cilium versiones anteriores a 1.9.16, 1.10.11 y 1.11.15, contiene una vulnerabilidad de permisos por defecto incorrectos. Los sistemas operativos con usuarios pertenecientes al grupo ID 1000 pueden acceder a la API de Cilium por medio de un socket de dominio Unix disponible en el host donde es ejecutado Cilium. Esto podría permitir a usuarios maliciosos comprometer la integridad así como la disponibilidad del sistema en ese host. El problema ha sido corregido y el parche está disponible en las versiones 1.9.16, 1.10.11 y 1.11.5. Una posible mitigación es modificar el DaemonSet de Cilium para que sea ejecutado con un determinado comando, que puede encontrarse en el aviso de seguridad de GitHub para esta vulnerabilidad
