Lifecycle Timeline
2Description
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
Analysis
Ev.Energy's WebSocket implementation accepts duplicate session identifiers from multiple endpoints, allowing attackers to hijack active charging station sessions through predictable identifier prediction. An unauthenticated remote attacker can impersonate legitimate stations to intercept commands, authenticate as other users, or disrupt service by flooding the backend with spoofed session requests. …

Remediation
Within 24 hours: Inventory all affected charging stations and document current session management practices; implement network monitoring for suspicious WebSocket connection patterns. Within 7 days: Deploy compensating controls (see below), restrict WebSocket access to trusted networks only, and brief incident response teams. …
