SteVe is an open platform that implements different version of the OCPP protocol for Electric Vehicle charge points, acting as a central server for management of registered charge points. Attackers can inject arbitrary HTML and Javascript code via WebSockets leading to persistent Cross-Site Scripting in the SteVe management interface.

SteVe Community ocpp-jaxb before 0.0.8 generates invalid timestamps such as ones with month 00 in certain situations (such as when an application receives a StartTransaction Open Charge Point Protocol message with a timestamp parameter of 1000000). This may lead to a SQL exception in applications, and may undermine the integrity of transaction records.
