CVE-2026-28776

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.

Summary		(es) El receptor de satélite SuperFlex de la serie SFX de International Datacasting Corporation (IDC) contiene credenciales codificadas de forma rígida para la cuenta 'monitor'. Un atacante remoto no autenticado puede usar estas credenciales triviales y no documentadas para acceder al sistema a través de SSH. Aunque inicialmente se le coloca en un shell restringido, el atacante puede evadirse trivialmente para lograr la funcionalidad de shell estándar.
