CVE-2026-126723 · Severity: info · Published 2026-11-11

The Rooxis RXR-12 Wi-Fi router's web management interface contains a vulnerability that allows authenticated administrators to execute arbitrary commands with root privileges through the MAC address whitelist/blacklist feature. An attacker with admin access can gain complete control of the router, potentially intercepting network traffic or using it as a foothold for further attacks.

## Technical details

The LuCI web UI's white_list RPC handler (/usr/lib/lua/luci/data/white_list_plt.lua) passes unsanitized user-supplied MAC address parameters directly to os.execute() without validation, despite having a validator function that unconditionally returns success. An authenticated administrator can inject shell metacharacters in the mac parameter to achieve root command execution. This vulnerability requires valid admin credentials and remains unfixed in the vendor's remediation build 20260813_c2169ea5.
