Name of the Vulnerable Software and Affected Versions WebSocket Application Programming Interface (affected versions not specified)

Description The WebSocket Application Programming Interface does not restrict the number of authentication requests. This lack of rate limiting could enable an attacker to perform denial-of-service attacks by disrupting or misdirecting legitimate charger telemetry. It may also allow brute-force attacks to gain unauthorized access. The API endpoints are susceptible to abuse due to the missing rate limiting on authentication requests. The authentication process is vulnerable to excessive requests.

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