Description
An authenticated Redis session could be used to obtain full root access to all servers in the CVX cluster. Note that this would require an attacker to have both network access to the Redis service on a CVX server and the Redis password. Please note that all Redis communication, including authentication, occurs over plaintext in the present day. TLS support is tracked under RFE1294850.
