Scanner FTP Auxiliary Modules


anonymous





The ftp/anonymous scanner will scan a range of IP addresses searching for FTP servers that allow anonymous access and determines where read or write permissions are allowed.





msf > use auxiliary/scanner/ftp/anonymous
msf auxiliary(anonymous) > show options

Module options:

Name Current Setting Required Description
---- --------------- -------- -----------
FTPPASS mozilla@example.com no The password for the specified username
FTPUSER anonymous no The username to authenticate as
RHOSTS yes The target address range or CIDR identifier
RPORT 21 yes The target port
THREADS 1 yes The number of concurrent threads




Configuring the module is a simple matter of setting the IP range we wish to scan along with the number of concurrent threads and let it run.

ftp_login





The ftp_login auxiliary module will scan a range of IP addresses attempting to log in to FTP servers.





msf > use auxiliary/scanner/ftp/ftp_login 
msf auxiliary(ftp_login) > show options

Module options (auxiliary/scanner/ftp/ftp_login):

Name Current Setting Required Description

DB_ALL_PASS false no Add all passwords in the current database to the list
DB_ALL_USERS false no Add all users in the current database to the list
PASSWORD no A specific password to authenticate with
PASS_FILE /usr/share/wordlists/fasttrack.txt no File containing passwords, one per line
Proxies no A proxy chain of format type:host:port[,type:host:port][...]
RECORD_GUEST false no Record anonymous/guest logins to the database
RHOSTS yes The target address range or CIDR identifier

As we can see, the scanner successfully logged in to one of our targets with the provided credentials.





ftp_version





The ftp_version module simply scans a range of IP addresses and determines the version of any FTP servers that are running.





msf > use auxiliary/scanner/ftp/ftp_version
msf auxiliary(ftp_version) > show options

Module options:

Name Current Setting Required Description
---- --------------- -------- -----------
FTPPASS mozilla@example.com no The password for the specified username
FTPUSER anonymous no The username to authenticate as
RHOSTS yes The target address range or CIDR identifier
RPORT 21 yes The target port
THREADS 1 yes The number of concurrent threads




To setup the module, we just set our RHOSTS and THREADS values and let it run.





msf auxiliary(ftp_version) > set RHOSTS 192.168.1.200-254
RHOSTS => 192.168.1.200-254
msf auxiliary(ftp_version) > set THREADS 55
THREADS => 55
msf auxiliary(ftp_version) > run
