Vulnerability Title
EVoke Systems EVoke CSMS Insufficient Session Expiration
Source: CVE Program / CVE List V5
Vulnerability Description
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.
