# Cudy TR3000 router: OpenVPN config import lets admins run root commands

Link for people: https://infrastack.ai/live/CVE-2026-129099 (this .md is for agents)

Cudy TR3000 routers before 2.5.42 accept OpenVPN client configurations whose tls-verify or ipchange directives are not filtered by an incomplete denylist. An authenticated administrator who imports a malicious config can run commands as root when the router connects to an attacker-controlled VPN endpoint.

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

## How to check

- Check the firmware version on the router's admin interface against `2.5.42`
- Review imported OpenVPN client configurations for `tls-verify` or `ipchange` directives

## Fix

- Cudy TR3000: move to `2.5.42` or later

## Timeline

## From the sources

Cudy TR3000 before 2.5.42 contains a remote code execution vulnerability that allows authenticated administrators to run root commands by importing a malicious OpenVPN client configuration. Attackers can include tls-verify or ipchange directives, which the incomplete denylist does not filter, to execute commands as root when the router connects to an attacker-controlled VPN endpoint.
