Additional Advisory Data
Workarounds
CNA: Monta states that they are actively working to increase adoption of authenticated connections across their network and to deprecate unauthenticated access on a rolling basis. Monta states that they provide support for OCPP 1.6 Security Profile 2 (HTTP Basic Auth with TLS) and encourage operators to enable it.
CNA: Monta states that they have implemented rate limiting and automated connection throttling at the WebSocket layer. Connections exhibiting abusive patterns, including rapid reconnection, ID brute-forcing behavior, or excessive command volume, are automatically identified and blocked.
CNA: Monta states that their platform handles duplicate connection attempts per the OCPP specification, where a new authenticated connection supersedes an existing session for the same station ID.
