Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/nessus/nessus_ntp_login
msf auxiliary(nessus_ntp_login) > show options
... show and set options ...
msf auxiliary(nessus_ntp_login) > set RHOSTS ip-range
msf auxiliary(nessus_ntp_login) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(nessus_ntp_login) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(nessus_ntp_login) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(nessus_ntp_login) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Module advanced options (auxiliary/scanner/nessus/nessus_ntp_login):
Name Current Setting Required Description
---- --------------- -------- -----------
CHOST no The local client address
CPORT no The local client port
ConnectTimeout 10 yes Maximum number of seconds to establish a TCP connection
MaxGuessesPerService 0 no Maximum number of credentials to try per service instance. If set to zero or a non-number, this option will not be used.
MaxGuessesPerUser 0 no Maximum guesses for a particular username for the service instance. Note that users are considered unique among different services, so a user at 10.1.1.1:22 is different from one at 10.2.2.2:
22, and both will be tried up to the MaxGuessesPerUser limit. If set to zero or a non-number, this option will not be used.
