Executive Summary

This vulnerability occurs because the JWT secret key is hard-coded and embedded in the egOS WebGUI backend, making it readable to the default user. As a result, an unauthenticated remote attacker can obtain this secret key and generate valid HS256 tokens, allowing them to bypass authentication and authorization mechanisms.

Impact Analysis

An attacker exploiting this vulnerability can gain unauthorized access to the system by creating valid authentication tokens without needing valid credentials. This can lead to full compromise of confidentiality, integrity, and availability of the affected system.
