# Rooxis RXR-12 router: authenticated command injection gives root shell

Link for people: https://infrastack.ai/live/CVE-2026-126723 (this .md is for agents)

The Rooxis RXR-12 Wi-Fi router's LuCI white_list RPC handler concatenates an unvalidated MAC address parameter into os.execute(), so a logged-in user can run arbitrary commands as root. Firmware 20260813_c2169ea5 fixes the flaw, and the router can be updated through its local web interface.

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

## How to check

- Check the router's current firmware version in its local web interface (the version shown in the status or system page) and compare it with `20260813_c2169ea5`.
- Confirm whether the device runs the vulnerable white_list RPC handler at `/usr/lib/lua/luci/data/white_list_plt.lua`; the sources do not say how to verify this from outside the device.

## Fix

- Rooxis RXR-12: update to firmware `20260813_c2169ea5` or later.

## Timeline

- 2026-11-11T17:28:22+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-126723

## From the sources

Rooxis RXR-12 Wi-Fi router contains an authenticated command injection vulnerability in the LuCI white_list RPC handler (/usr/lib/lua/luci/data/white_list_plt.lua), where unsanitized user-supplied MAC addresses are concatenated into os.execute() without validation, yielding root command execution via a malformed mac parameter. Firmware 20260813_c2169ea5 fixes the vulnerability, and users can update their router through the local web interface.
