# WHATPORT(32400)

## NAME

port 32400 — Plex Media Server — Plex Media Server's web UI and API — someone on the network is running a media library.

Protocol: TCP  
IANA registry

## DESCRIPTION

Plex Media Server binds TCP 32400 for its web app (/web), its HTTP API, and all media streaming; the port is formally registered to Plex Inc. with IANA. It appears on scans of NAS boxes, home servers, and desktops, and Plex's remote-access feature deliberately maps it through the router via UPnP or a manual forward. An unauthenticated GET /identity returns the server's machineIdentifier and version, which is how you fingerprint one.

## EXPOSURE

**Expose with care.** Plex is designed for internet exposure with account-based auth and relays, but it has shipped pre-auth vulnerabilities (CVE-2020-5741 among them), so expose it only on a current version with remote access managed by Plex rather than a hand-rolled forward.

## CHECK

```sh
curl -s -m 3 http://TARGET:32400/identity
```
