Lifecycle Timeline
2Description
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
Analysis
Ev.Energy's WebSocket API fails to implement rate limiting on authentication attempts, enabling attackers to launch denial-of-service attacks against charger telemetry systems or conduct brute-force credential attacks without restriction. This vulnerability affects all unauthenticated network-based interactions with the affected application and has no available patch at this time.

Remediation
Within 24 hours: Identify all systems using WebSocket APIs and assess exposure; enable audit logging on authentication attempts. Within 7 days: Implement rate-limiting controls via WAF or API gateway; deploy IP-based throttling (max 5 failed auth requests per minute per IP); segment WebSocket endpoints if possible. …
