Default Password (nsroot) for 'nsroot' Account

Critical Nessus Plugin ID 66393


The remote system can be accessed with a default account.


The account 'nsroot' on the remote host has the password 'nsroot'.

An attacker may leverage this issue to gain administrative access to the affected system.

Note that Citrix NetScaler appliances are known to use these credentials to provide complete, administrative access to the Citrix NetScaler appliance.


If the host is a Citrix NetScaler, reset the nsroot password.

Otherwise, set a strong password for this account or use ACLs to restrict access to the host.
