# Cudy TR3000 router: admin can inject OpenVPN options and run root commands

Link for people: https://infrastack.ai/live/CVE-2026-129101 (this .md is for agents)

Cudy TR3000 routers before 2.5.42 let an authenticated administrator set arbitrary OpenVPN server options through the vpn.set_conf RPC method. Setting a malicious up option makes the openvpn-hotplug wrapper run it with /bin/sh as root.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the router firmware version in the admin web interface and compare it with `2.5.42`.
- Confirm the device is a Cudy TR3000 before looking further.

## Fix

- Cudy TR3000: move to `2.5.42` or later.

## From the sources

Cudy TR3000 before 2.5.42 contains a mass assignment vulnerability in the vpn.set_conf App RPC method that allows authenticated administrators to inject arbitrary OpenVPN server options. Attackers can set enabled=1 and a malicious up option in the openvpns object, which the openvpn-hotplug wrapper executes via /bin/sh as root.
