CVE-2026-28778

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-28778
International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver contains undocumented, hardcoded/insecure credentials for the `xd` user account. A remote unauthenticated attacker can log in via FTP using these credentials. Because the `xd` user has write permissions to their home directory where root-executed binaries and symlinks (such as those invoked by `xdstartstop`) are stored, the attacker can overwrite these files or manipulate symlinks to achieve arbitrary code execution as the root user.

Summary
  • (es) El receptor de satélite SuperFlex de la serie SFX de International Datacasting Corporation (IDC) contiene credenciales no documentadas, codificadas/inseguras para la cuenta de usuario 'xd'. Un atacante remoto no autenticado puede iniciar sesión a través de FTP utilizando estas credenciales. Debido a que el usuario 'xd' tiene permisos de escritura en su directorio de inicio, donde se almacenan binarios ejecutados por root y enlaces simbólicos (como los invocados por 'xdstartstop'), el atacante puede sobrescribir estos archivos o manipular enlaces simbólicos para lograr la ejecución de código arbitrario como usuario root.
