Vulnerability from github – Published: 2026-03-04 09:31 – Updated: 2026-03-17 18:30

Details

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.
