CloudCharge WebSocket API Rate Limiting Vulnerability Allowing Denial-of-Service and Brute-Force Attacks

Vulnerability

A vulnerability exists in the CloudCharge WebSocket API due to a lack of rate limiting on authentication requests. This flaw could enable an attacker to perform denial-of-service attacks by disrupting legitimate charger telemetry or to conduct brute-force attacks to gain unauthorized access. The vulnerability affects all versions of CloudCharge's web application.

Impact

Exploitation of this vulnerability could lead to denial-of-service conditions by misrouting or suppressing legitimate traffic, causing significant disruptions. Additionally, the absence of rate limiting could be exploited to perform brute-force attacks, potentially leading to unauthorized access.
