Doc Text:
A flaw was found in Rooxis RXR-12. An authenticated attacker can execute arbitrary commands with root privileges on the device. This issue occurs because the router's web management interface fails to validate and sanitize user-supplied Media Access Control (MAC) addresses before executing them within underlying operating system commands.

Description OSIDB Bzimport 2026-11-11 16:51:19 UTC
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.
