# Cudy TR3000 router: authenticated admins run commands as root via WireGuard key

Link for people: https://infrastack.ai/live/CVE-2026-75577 (this .md is for agents)

Cudy TR3000 routers before 2.5.42 let an administrator store a WireGuard private key containing shell substitution, which is then passed to a shell command. An attacker with admin access can run arbitrary commands as root on the router.

_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 web admin under System or Status; compare it with `2.5.42`.
- Look for the vpn.export_conf method in requests to /cgi-bin/luci/rpc/app on the router, if you have logs.

## Fix

- Cudy TR3000: move to firmware `2.5.42` or later (per the NVD range before 2.5.42).

## From the sources

Cudy TR3000 before 2.5.42 contains a command injection vulnerability that allows authenticated administrators to execute commands as root by storing a malicious WireGuard private key. Attackers can save a private_key containing $() shell substitution and call the vpn.export_conf method on the /cgi-bin/luci/rpc/app JSON-RPC endpoint, which passes the key to a wg pubkey shell command.
