Name of the Vulnerable Software and Affected Versions WebSocket backend (affected versions not specified)

Description The backend utilizes charging station identifiers to uniquely associate sessions but permits multiple endpoints to connect using the same session identifier. This results in predictable session identifiers, enabling session hijacking or shadowing where a newer connection replaces a legitimate charging station and receives intended backend commands. This may allow unauthorized authentication or a denial-of-service condition by overwhelming the backend with session requests. The vulnerability impacts the association of sessions via charging station identifiers and the handling of multiple connections with the same session identifier.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
