Описание
etcd is a distributed key-value store for the data of a distributed system. Prior to 3.5.32 and 3.6.13, when etcd is configured with --listen-client-http-urls to split HTTP and gRPC client endpoints onto separate listeners, the --client-crl-file Certificate Revocation List is not enforced on the gRPC listener, allowing a client with a revoked certificate to authenticate successfully over gRPC. This issue is fixed in versions 3.5.32 and 3.6.13.
A flaw was found in etcd, a distributed key-value store. When etcd is configured to use separate listeners for HTTP and gRPC client endpoints, the Certificate Revocation List (CRL) is not properly enforced on the gRPC listener. This oversight allows a client with a revoked certificate to successfully authenticate, potentially leading to unauthorized access and compromise of data integrity.
