An unused function in MicroServer can start a reverse SSH connection to a vendor registered domain, without mutual authentication. An attacker on the local network with admin access to the web server, and the ability to manipulate DNS responses, can redirect the SSH connection to an attacker controlled device.
Una función no utilizada en MicroServer puede iniciar una conexión SSH inversa a un dominio registrado por el proveedor, sin autenticación mutua. Un atacante en la red local con acceso de administrador al servidor web, y la capacidad de manipular respuestas DNS, puede redirigir la conexión SSH a un dispositivo controlado por el atacante.
