Charging Station Session Vulnerabilities

WebSocket session management in charging station backends allows multiple connections using identical session identifiers, enabling attackers to hijack legitimate sessions and intercept commands or impersonate authorized stations. Unauthenticated remote attackers can exploit this predictable identifier scheme to displace active connections, redirect backend communications, or launch denial-of-service attacks against the charging infrastructure. The vulnerability affects any deployment relying on this WebSocket backend without an available patch.

WebSocket session handling in charging station backends allows multiple connections to use identical session identifiers, enabling attackers to hijack active sessions and impersonate legitimate stations without authentication. An adversary can intercept backend commands intended for a target charging station or launch denial-of-service attacks by flooding the backend with spoofed session requests. This vulnerability affects any system relying on this WebSocket implementation and currently lacks an available patch.
