Summary

The WebSocket backend uses predictable session identifiers because multiple endpoints can connect using the same session identifier. This allows unauthorized users to impersonate others or cause a denial-of-service condition by overwhelming the backend with valid session requests.

Risk Assessment

The organization is at risk of unauthorized access to the system and potential service disruptions due to a Denial of Service attack.

Recommendation

Implement unique, unpredictable session identifiers for each WebSocket connection and restrict the ability to reuse the same identifier multiple times.

Original NVD description (English source)

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. 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.
