Additional Advisory Data
Solutions
CNA: EVoke states that as a hardware-agnostic platform supporting multiple charger Original Equipment Manufacturers OEMs, EVoke must interoperate with EVSE devices that support different OCPP security profiles depending on the firmware capabilities of the charger. EVoke CSMS currently supports all OCPP security profiles (0–3). However, the effective security configuration for a charger connection is determined by the security profile implemented in the EVSE firmware. Some legacy chargers deployed in the network support only Security Profile 0 or 1. These chargers were installed prior to the broader industry adoption of stronger authentication mechanisms defined in OCPP Security Profiles 2 and 3. EVoke is actively working with charger OEM partners to migrate supported devices to Security Profile 2 (TLS encryption with basic authentication) or Security Profile 3 (Mutual TLS authentication using client certificates). For OEMs that continue to support firmware updates, EVoke will prioritize upgrades to enable Security Profiles 2 or 3.
CNA: EVoke states that certain legacy charger models deployed on the network are no longer supported by the manufacturer (for example, chargers originally produced by EVBox). These devices cannot be upgraded to support stronger security profiles. For chargers limited to Security Profiles 0 or 1, EVoke is implementing additional server-side protections to mitigate spoofing risks. Allow-listed chargers will only be accepted from chargers whose IDs are registered in the EVoke CSMS inventory database. Unknown charger identifiers will be rejected.
Workarounds
CNA: EVoke states that to reduce the risk of duplicate sessions, only a single active connection per charger ID will be permitted. If a second connection using the same charger ID is detected, the new connection will be rejected or the previous session will be terminated. This prevents unauthorized actors from establishing parallel sessions using spoofed charger identifiers.
CNA: EVoke states that the platform will monitor session anomalies including repeated connection attempts, unexpected IP address changes, and abnormal message patterns. Security events will be logged and flagged for operational review.
CNA: EVoke states that to address the risk of denial-of-service via repeated authentication attempts, EVoke will implement connection rate limiting at the WebSocket gateway layer. These controls will restrict excessive connection attempts from the same source and temporarily block abusive traffic patterns.
CNA: EVoke states they are developing a lifecycle policy for legacy chargers that cannot support modern OCPP security profiles. This policy will include identification of unsupported EVSE models and risk classification Migration planning with site operators where possible
