No explicit patch links or vendor advisory content are provided. Until patched, restrict project member permissions to trusted users only and avoid using the Amphora provider if possible.
Description
In OpenStack Octavia before 18.0.1, the Amphora provider driver did not validate the listener and pool tls_ciphers field for control characters. The value is written verbatim into the HAProxy configuration generated on the amphora, and thus an authenticated project member who owns a TLS-enabled load balancer can embed a newline and inject arbitrary HAProxy configuration directives. Only deployments using the Amphora provider are affected.
