Technical details

This vulnerability is an OS command injection flaw (CWE-78) in the /index.php/ajax/parameterManage endpoint. A low-privileged remote attacker with valid user credentials can inject arbitrary shell commands into endpoint parameters, which are then executed with root privileges on the device. The attack requires network access and valid user authentication but no user interaction. An attacker can achieve full system compromise including code execution, data exfiltration, and persistent backdoor installation. Patches are available in firmware version 1.7.4 and later.
