Default Password (admin) for 'root' Account

Critical Nessus Plugin ID 40355


The remote system can be accessed with a default administrator account.


The account 'root' on the remote host has the password 'admin'.
An attacker may leverage this issue to gain access, likely as an administrator, to the affected system.

Note that DD-WRT, an open source Linux-based firmware popular on small routers and embedded systems, is known to use these credentials by default.


Change the password for this account or disable it.
