Descriptions

An authentication bypass vulnerability was discovered in kube-apiserver. This issue could allow a remote, authenticated attacker who has been given permissions "update, patch" the "pods/ephemeralcontainers" subresource beyond what the default is. They would then need to create a new pod or patch one that they already have access to. This might allow evasion of SCC admission restrictions, thereby gaining control of a privileged pod.

Se descubrió una vulnerabilidad de omisión de autenticación en kube-apiserver. Este problema podría permitir que un atacante remoto y autenticado al que se le hayan otorgado permisos "update, patch" el subrecurso "pods/ephemeralcontainers" más allá de lo predeterminado. Luego tendrían que crear un nuevo pod o parchear uno al que ya tengan acceso. Esto podría permitir la evasión de las restricciones de admisión de SCC, obteniendo así el control de un módulo privilegiado.

*Credits: This issue was discovered by Xingxing Xia (Red Hat).
