CVE-2026-126720

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.
