# Cudy TR3000 router: malicious management server runs commands as root

Link for people: https://infrastack.ai/live/CVE-2026-75495 (this .md is for agents)

Cudy TR3000 routers before 2.5.42 let a malicious or compromised ACS (TR-069 management server) run shell commands as root through a crafted password value in SetParameterValues requests. An attacker who controls or hijacks the management server gets full root control of the router.

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

## Affected

- vendor:Cudy TR3000 affected range not listed fixed no fixed version listed

## How to check

- Check the firmware version in the router's web admin page (System or Status) and compare it with `2.5.42`.
- Check whether TR-069 remote management (obuspa, ACS URL) is enabled in the router's settings.

## Fix

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

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/cudy-tr3000-before-2.5.42-os-command-injection-via-tr-098-user-password-parameter

## From the sources

Cudy TR3000 before 2.5.42 contains an OS command injection vulnerability that allows a malicious or compromised ACS to execute commands as root by supplying a crafted InternetGatewayDevice.User.{i}.Password value. Attackers can send a SetParameterValues request with shell metacharacters that obuspa_system.lua concatenates into a luci.util.exec() command string, gaining root command execution.
