SteVe v3.6.0 was discovered to use predictable transaction ID's when receiving a StartTransaction request. This vulnerability can allow attackers to cause a Denial of Service (DoS) by using the predicted transaction ID's to terminate other transactions.

In SteVe, any authenticated charger can terminate any other charger's active transaction (missing ownership verification on StopTransaction)

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.

An issue in the web socket handshake process of SteVe v3.7.1 allows attackers to bypass authentication and execute arbitrary coammands via supplying crafted OCPP requests.
