CyberRota Analysis
AI-GeneratedA vulnerability exists in etcd versions prior to 3.5.32 and 3.6.13, where the Certificate Revocation List (CRL) is not enforced on the gRPC listener when HTTP and gRPC client endpoints are separated. This allows clients with revoked certificates to authenticate successfully, potentially compromising the integrity of the system. Organizations using affected versions of etcd should prioritize upgrading to the patched versions to mitigate the risk of unauthorized access.

Original NVD Description
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.
