CVE-2026-2754Network attack vector

Information disclosure via verbose exception stack traces

Published Mar 6, 2026 · Updated Mar 6, 2026

Information disclosure in NAVTOR NavBox 4.12.0.3 allows remote attackers to read internal application details via crafted HTTP requests. An HTTP request triggers an unhandled exception, and the affected endpoint returns a verbose stack trace containing sensitive internal application details. Network access to the onboard appliance is required; no authentication or user interaction is needed, and the disclosed data supports reconnaissance rather than modification or service interruption.
