Additional Advisory Data
Solutions
CNA: IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls: 1-Enforce modern security profiles and stronger authentication. 2-Device level whitelisting was implemented to ensure authorized devices connect. 3-Rate limiting controls prevent excessive requests and reduces denial-of-service attacks. 4-Enhanced automated monitoring and alerting to detection abnormal network activity.
CNA: Devices using the encrypted deployment of eParking's OCPP servers or IGL-Technologies proprietary eTolppa protocol are not impacted by these vulnerabilities.
CNA: To prevent this in the future IGL-Technologies will continue vulnerability monitoring under their ISO 27001:2022 security program and tighten security requirements for future third‑party OCPP hardware approvals.
