cert

The cert scanner module is a useful administrative scanner that allows you to cover a subnet to check whether or not server certificates are expired.

Module options:

   THREADS  1                yes       The number of concurrent threads

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

The module output shows the certificate issuer, the issue date, and the expiry date.

dir_listing

The dir_listing module will connect to a provided range of web servers and determine if directory listings are enabled on them.

As can be seen in the above output, one of our scanned servers does indeed have directory listings enabled on the root of the server. Findings like these can turn into a gold mine of valuable information.

dir_scanner

The dir_scanner module scans one or more web servers for interesting directories that can be further explored.

Our quick scan has turned up a number of directories on our target server that we would certainly want to investigate further.

dir_webdav_unicode_bypass

The dir_webdav_unicode_bypass module scans a given range of webservers and attempts to bypass the authentication using the WebDAV IIS6 Unicode vulnerability.

enum_wayback

The enum_wayback auxiliary module will query the archive.org site for any url’s that have been archived for a given domain. This can be useful for locating valuable information or for finding pages on a site that have since been unlinked.

verb_auth_bypass

The verb_auth_bypass module scans a server or range of servers and attempts to bypass authentication by using different HTTP verbs.

   VHOST                       no        HTTP server virtual host

We configure this module by setting the path to the page requiring authentication, set our RHOSTS value and let the scanner run.

msf auxiliary(verb_auth_bypass) > set PATH /xampp/
PATH => /xampp/
msf auxiliary(verb_auth_bypass) > set RHOSTS 192.168.1.201

By reading the returned server status codes, the module indicates there is a potential auth bypass by using the TRACE verb on our target.

webdav_scanner

The webdav_scanner module scans a server or range of servers and attempts to determine if WebDav is enabled. This allows us to better fine-tune our attacks.

wordpress_login_enum

The wordpress_login_enum auxiliary module will brute-force a WordPress installation and first determine valid usernames and then perform a password-guessing attack.
