Original NVD Description

An issue was discovered in Dalmann OCPP.Core before 1.2.0 for OCPP (Open Charge Point Protocol) for electric vehicles. It does not validate the length of the chargePointVendor field in a BootNotification message, potentially leading to server instability and a denial of service when processing excessively large inputs. NOTE: the vendor's perspective is "OCPP.Core is intended for use in a protected environment/network."
