Authentication Request Rate Limiting Flaw in WebSocket API Enables DoS, Brute-Force

Executive Summary

This vulnerability exists because the WebSocket Application Programming Interface does not limit the number of authentication requests that can be made.

Without such rate limiting, an attacker can exploit this by sending many authentication requests.

This can lead to denial-of-service attacks by interfering with legitimate charger telemetry or allow brute-force attacks to gain unauthorized access.

Impact Analysis

The vulnerability can impact you by enabling attackers to perform denial-of-service attacks that suppress or mis-route legitimate charger telemetry.

Additionally, attackers may use brute-force methods to gain unauthorized access to the system.

This could disrupt normal operations and compromise system security.
