Insecure Transport

go.etcd.io/etcd/client/pkg/v3 is vulnerable to Insecure Transport. The vulnerability is due to default weak ciphers configuration...

Improper Certificate Validation

go.etcd.io/etcd is vulnerable to Improper Certificate Validation. The vulnerability is due to etcd gateway's handling of endpoint validation when the --discovery-srv flag is enabled, because it only checks for TCP reachability without ensuring that the endpoint accepted TLS connections through...

Inaccurate Logging

go.etcd.io/etcd is vulnerable to Inaccurate Logging. The vulnerability is due to errors being logged with insufficient information regarding why the authentication failed. This may be misleading while auditing etcd logs...

Etcd Gateway can include itself as an endpoint resulting in resource exhaustion

Vulnerability type Denial of Service Detail The etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesti...

Missing Release of Resource after Effective Lifetime

In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requestin...
