Navtor NavBox exposes sensitive configuration and operational data due to missing authentication on HTTP API endpoints. An unauthenticated remote attacker with network access to the device can execute HTTP GET requests to TCP port 8080 to retrieve internal network parameters including ECDIS & OT Information, device identifiers, and service status logs.

CVE-2026-2754 identifies a critical security flaw in Navtor NavBox version 4.12.0.3, a maritime navigation and operational technology device. The vulnerability arises because the device's HTTP API endpoints on TCP port 8080 do not enforce any authentication, allowing unauthenticated remote attackers with network access to retrieve sensitive configuration and operational data. Specifically, attackers can execute HTTP GET requests to access internal network parameters, including Electronic Chart Display and Information System (ECDIS) data, Operational Technology (OT) information, device identifiers, and service status logs. This exposure is due to CWE-306, which denotes missing authentication for critical functions, a serious security design flaw. The vulnerability has a CVSS 3.1 base score of 7.5, reflecting high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to confidentiality (C:H), without affecting integrity or availability. Although no public exploits have been observed, the disclosed information could facilitate further targeted attacks or unauthorized access to maritime operational systems. NavBox is widely used in maritime navigation, making this vulnerability particularly concerning for vessels and maritime infrastructure relying on this product. The lack of authentication on sensitive API endpoints represents a critical security oversight that must be addressed to prevent unauthorized data disclosure and potential operational risks.
