Description An authenticated OS command injection exists in the '/cgi-bin/dispatcher.cgi' endpoint. The web smtp test post handler fails to sanitize the SMTP server value provided by the user before incorporating it into a shell command. A remote attacker with administrator web credentials can exploit this by sending a crafted SMTP server value to execute arbitrary operating-system commands on the device.
