AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability occurs because the WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This leads to predictable session identifiers and enables session hijacking or shadowing, where the most recent connection can displace the legitimate charging station and receive backend commands intended for that station.
How can this vulnerability impact me? :
The vulnerability may allow unauthorized users to authenticate as other users, potentially gaining access to their sessions. Additionally, a malicious actor could cause a denial-of-service condition by overwhelming the backend with valid session requests, disrupting normal operations.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
