Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
International Datacasting Corporation (IDC) SFX Series SuperFlex SatelliteReceiver contains hardcoded credentials for the `monitor` account. A remote unauthenticated attacker can use these trivial, undocumented credentials to access the system via SSH. While initially dropped into a restricted shell, the attacker can trivially break out to achieve standard shell functionality.
