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 and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. 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.

Analysis

Chargemap.Com's WebSocket backend accepts multiple connections with identical session identifiers, allowing attackers to hijack charging station sessions and intercept backend commands through predictable identifier prediction. An unauthenticated remote attacker can impersonate legitimate charging stations, execute unauthorized operations, or disrupt service availability by flooding the backend with crafted session requests. …

Remediation

Within 24 hours: Isolate affected WebSocket endpoints from production traffic and enable enhanced logging on all WebSocket connections to detect exploitation attempts. Within 7 days: Deploy network segmentation to restrict WebSocket access to authorized networks only and implement strict session validation controls at the application layer. …
