# Cudy TR3000 router: admin can run commands as root via OpenVPN keys

Link for people: https://infrastack.ai/live/CVE-2026-129100 (this .md is for agents)

Cudy TR3000 routers before 2.5.42 let an authenticated administrator upload a crafted OpenVPN private or tls-auth key that injects OpenVPN directives. OpenVPN then runs an attacker-chosen hook as root.

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

## How to check

- Check the firmware version in the router's admin web interface (System or Status page) and compare it to `2.5.42`.
- Look for OpenVPN key or certificate upload settings and whether they are in use.

## Fix

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

## From the sources

Cudy TR3000 before 2.5.42 contains a remote code execution vulnerability that allows authenticated administrators to execute commands as root by uploading crafted OpenVPN private or tls-auth keys. Attackers can close the inline key block with </key>, inject directives such as tls-verify that bypass the .ovpn denylist, and have OpenVPN execute the hook as root.
