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.
On affected modular platforms running Arista EOS equipped with both redundant supervisor modules and having the redundancy protocol configured with RPR or SSO, an existing unprivileged user can login to the standby supervisor as a root user, leading to a privilege escalation. Valid user credentials are required in order to exploit this vulnerability.
On affected versions of the Arista CloudVision Portal (CVP on-prem), the time-bound device onboarding token can be used to gain admin privileges on CloudVision.
