CVE-2023-53881Public exploitNetwork attack vector

Command execution via forged CWMP server responses

Published Dec 15, 2025 · Updated Dec 15, 2025

Cleartext CWMP communication in Ruijie Networks ReyeeOS 1.204.1614 allows man-in-the-middle attackers to execute arbitrary commands. The device polls its CWMP server over unencrypted HTTP and accepts an X_RUIJIE_COM_CN_ExecuteCliCommand response as a command to run. An attacker must intercept and redirect the device's outbound polling traffic to a fake CWMP server, which grants command execution on the appliance.
