Technical details

A missing authentication vulnerability (CWE-306) exists in the HTTP API of Navtor NavBox. The flaw is located on TCP port 8080, where several endpoints fail to verify user identity before granting access to sensitive data. By sending unauthenticated HTTP GET requests, a remote attacker can extract internal network parameters, Electronic Chart Display and Information System (ECDIS) data, Operational Technology (OT) information, and service logs. Additionally, certain requests may trigger unhandled exceptions that disclose verbose stack traces, further revealing internal application architecture. The vulnerability is addressed in version 4.16.2.4.
