Port 9090SqueezeCenter CLI

Port 9090 is primarily used for Logitech Media Server's Command Line Interface (CLI), previously known as SqueezeCenter. This service allows external applications and scripts to communicate with and control media streaming, playback, and library management tasks. While unofficial, it's widely adopted for remote server management due to its flexible command structure..

Technical Details

what runs on :9090

Port 9090 is utilized by the Logitech Media Server (formerly SqueezeCenter or SlimServer) for its dedicated CLI used in controlling media playback, managing playlists, and interfacing with player devices. Communication over this port typically involves plain-text command strings and responses, enabling automation and integration with third-party applications or scripts.

The CLI on port 9090 provides a comprehensive set of instructions to manipulate the media server, including browsing the media library, controlling individual zone players, and retrieving system or playback status. Since it only supports text-based commands over TCP, it is easy to implement clients in virtually any programming language.

Unlike the web interface served on port 9000, port 9090 is optimized for programmatic access, making it suitable for remote control via home automation systems or customized remote apps. It typically operates on the local network but can be exposed externally for advanced use cases, with caution.

security overview

Common Vulnerabilities:

  • Lack of encryption means credentials or commands can be intercepted via network sniffing.
  • Potential for unauthorized control if the port is exposed to untrusted networks without restriction.
  • Susceptible to brute-force attacks if password protections are weak or absent.

Common Mitigations:

  • Restrict port access to trusted IP addresses or devices within the local network.
  • Use strong, unique passwords for server access.
  • Employ network-level encryption like SSH tunnels or VPNs when accessing remotely.
  • Avoid exposing the port directly to the internet; instead, proxy through secure services.
  • Regularly update Logitech Media Server to patch any known vulnerabilities.
