Detail

The TLS ciphers list supported by etcd contains insecure cipher suites. Users can configure the desired ciphers using the “–cipher-suites” flag, and a default list of secure cipher suites is used if empty.

Workarounds

By default, no action is required. If users want to specify cipher suites using the ‘–cipher-suites’ flag, they should try not to specify insecure cipher suites. Please refer to the security documentation.
