# Rooxis RXR-12 Wi-Fi router: hidden root account with fixed default password

Link for people: https://infrastack.ai/live/CVE-2026-126724 (this .md is for agents)

The Rooxis RXR-12 Wi-Fi router ships with an undocumented account named dg that has root privileges and the firmware-wide default password ivanlee. An attacker who knows this can log in as root over SSH or the local console and take full control of the router.

_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 web interface against `20260813_c2169ea5`
- Try logging in over SSH with user `dg` and password `ivanlee` on a device you own; unknown whether the sources give a further check

## Fix

- Update the RXR-12 firmware to `20260813_c2169ea5`, which removes the account and disables root password authentication over SSH
- The update can be applied through the local web interface

## Timeline

- 2026-11-11T17:28:22+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-126724

## From the sources

Rooxis RXR-12 Wi-Fi router contains an undocumented UID-0 backdoor account (dg) with a firmware-wide default password (ivanlee) and interactive shell (/bin/ash), allowing authentication as root via SSH or local console without device-specific secrets. Firmware 20260813_c2169ea5 removes the account from the shipped root filesystem and disables root password authentication in SSH. Users can update their router can be through the local web interface.
