CVE-2019-19356
Netis WF2419 is vulnerable to authenticated Remote Code Execution (RCE) as root through the router Web management page. The vulnerability has been found in firmware version V1.2.31805 and V2.2.36123. After one is connected to this page, it is possible to execute system commands as root through the tracert diagnostic tool because of lack of user input sanitizing.
