CVE-2026-2752: Navtor Navbox Firmware

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

Navtor NavBox allows information disclosure via the /api/ais-data endpoint. A remote, unauthenticated attacker can send crafted requests to trigger an unhandled exception, causing the server to return verbose .NET stack traces. These error messages expose internal class names, method calls, and third-party library references (e.g., System.Data.SQLite), which may assist attackers in mapping the application's internal structure.

Affected products

• Navtor Navbox Firmware: from 4.12.0.3, before 4.16.2.4 (fixed in 4.16.2.4)
