CVE-2026-2249Network attack vector

Unauthenticated command execution via exposed web shell

Published Feb 11, 2026 · Updated Feb 11, 2026

Missing authentication in METIS DFS oscore 2.1.234-r18 and earlier allows remote attackers to run commands as daemon via /console. The web server exposes an interactive shell at /console and routes HTTP GET requests to it without verifying a session token, credentials, or request origin. Network access to the device's HTTP service is sufficient; exploitation permits daemon-level reads and writes to configurations and databases and service disruption.
