critical Nessus Plugin ID 10380


It was possible to log on this machine without password.


Using common usernames as well as the usernames reported by 'finger', Nessus was able to log in through rsh. Either the accounts are not protected by passwords or the ~/.rhosts files are not configured properly.

This vulnerability is confirmed to exist in Cisco Prime LAN Management Solution, but could be present on any host that is not securely configured.


If the remote host is a Cisco Prime LAN Management Solution virtual appliance, apply the relevant patch referenced in Cisco security advisory cisco-sa-20130109-lms.

Otherwise, remove the .rhosts files or set a password on the impacted accounts.
