Kubernetes Misconfiguration: Overly Broad Certificate Trust
Abstract
Uma instância etcd aceita conexões TLS de pares que usam certificados autoassinados.
Explanation
O Kubernetes mantém dados confidenciais em um cluster etcd. Portanto, cada instância do etcd deve aceitar apenas conexões de pares autenticados e autorizados e rejeitar quaisquer pares que usem certificados autoassinados para conexões TLS.
Exemplo 1: A configuração a seguir inicia uma instância etcd e define o sinalizador
Exemplo 1: A configuração a seguir inicia uma instância etcd e define o sinalizador
--peer-auto-tls
como true
. Como resultado, a instância etcd usa certificados autoassinados para conexões TLS com pares.
...
spec:
containers:
- command:
...
- etcd
...
- --peer-auto-tls=true
