VPR Score: 5.9


The remote router does not have a password set.


The remote host is running OpenWrt, an open source Linux distribution for embedded devices, especially routers.

It is currently configured without a password, which is the case by default. Anyone can connect to the device via Telnet and gain administrative access to it.


Set a password for the device.
