# Rooxis RXR-12 Wi-Fi router: unauthenticated remote code execution as root

Link for people: https://infrastack.ai/live/CVE-2026-126720 (this .md is for agents)

The Rooxis RXR-12 router's cloud_manage component passes a JSON field from its cloud server straight into popen(), so commands run as root. An attacker positioned on the network path can send a crafted response over cleartext HTTP and run arbitrary commands on the router.

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

## Affected

- vendor:Rooxis RXR-12 affected range not listed fixed no fixed version listed

## How to check

- Check the router's firmware version in its web interface; unknown otherwise
- Confirm whether `/usr/bin/cloud_manage` is present on the device (unknown if the sources do not say how to reach it)

## Fix

- Rooxis RXR-12: firmware `20260813_c2169ea5` or later, installed through the router's local web interface

## Timeline

- 2026-11-11T17:28:22+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-126720

## From the sources

Rooxis RXR-12 Wi-Fi router contains an unauthenticated remote code execution vulnerability in /usr/bin/cloud_manage, where a server-controlled JSON diagnoseParameter field is passed unsanitized to popen(), enabling arbitrary command execution as root over cleartext HTTP when an attacker is positioned on-path and has access to the hard-coded cloud endpoint. Firmware 20260813_c2169ea5 fixes the vulnerability, and your router can be updated through the local web interface.
