CVE-2023-49958 1 Dallmann-consulting 1 Open Charge Point Protocol 2024-11-21 7.5 High
An issue was discovered in Dalmann OCPP.Core through 1.2.0 for OCPP (Open Charge Point Protocol) for electric vehicles. The server processes mishandle StartTransaction messages containing additional, arbitrary properties, or duplicate properties. The last occurrence of a duplicate property is accepted. This could be exploited to alter transaction records or impact system integrity.
CVE-2023-49957 1 Dallmann-consulting 1 Open Charge Point Protocol 2024-11-21 7.5 High
An issue was discovered in Dalmann OCPP.Core before 1.3.0 for OCPP (Open Charge Point Protocol) for electric vehicles. It permits multiple transactions with the same connectorId and idTag, contrary to the expected ConcurrentTx status. This could result in critical transaction management and billing errors. NOTE: the vendor's perspective is "Imagine you've got two cars in your family and want to charge both in parallel on the same account/token? Why should that be rejected?"

NOTE: the vendor's perspective is "OCPP.Core is intended for use in a protected environment/network."
