CVE-2025-55705
📋 TL;DR
This vulnerability allows attackers to establish multiple concurrent sessions using the same charging station ID due to improper session management. This can lead to unauthorized access, data manipulation, and disruption of charging operations. It affects electric vehicle charging management systems that lack proper session expiration controls.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of charging infrastructure allowing attackers to manipulate billing data, disrupt charging services, or gain unauthorized access to backend systems.
Likely Case
Session hijacking leading to unauthorized charging sessions, data inconsistency, and potential billing manipulation.
If Mitigated
Limited impact with proper session management and monitoring in place, potentially only causing minor service disruptions.
🎯 Exploit Status
Exploitation requires valid charging station ID but no authentication for multiple concurrent sessions
