Adding and reviewing module documentation is a great way to contribute to the Metasploit Framework.
Before you write any module documentation, you should take a look at the sample template, module_doc_template.md, or take a look at any of the KBs that are already available.
Writing a KB
To write a KB, you’ll need to:
- Create a markdown (.md) file.
- Write the content.
- Save the file and name it after the module name. For example, the filename for ms08-067 is
modules/exploits/windows/smb/ms08_067_netapi.rb
, so its documentation isdocumentation/modules/exploits/windows/smb/ms08_067_netapi.md
. - Place it in the metasploit-framework/documentation/modules directory.
Where to put the markdown files
If you go to metasploit-framework/documentation/modules, you’ll see that there are documentation directories for each module type: auxiliary, exploit, payload, and post. To figure out where you need to put the file, you’ll need to look at the module’s path.
- Start msfconsole.
- Type
use <module name>
. - Type
info -d
. - When the module name appears, look at the Module field. You’ll see a file path for the module. That’s the path where the KB needs to be added.
For example:
msf> use auxiliary/scanner/smb/smb_login
msf (smb_login)> info
Name: SMB Login Check Scanner
Module: auxiliary/scanner/smb/smb_login
....
If you were creating a KB for the smb login scanner, you’d add it to metasploit-framework/documentation/modules/auxiliary/smb.md
.
Sections you should include in the KB
These are just suggestions, but it’d be nice if the KB had these sections:
- Vulnerable Applications - Tells users what targets are vulnerable to the module and provides instructions on how to access vulnerable targets for testing.
- Verification Steps - Tells users how to use the module and what the expected results are from running the module.
- Options - Provides descriptions of all the options that can be run with the module. Additionally, clearly identify the options that are required.
- Scenarios - Provides sample usage and describes caveats that the user may need to be aware of when running the module.
Before you submit your PR: msftidy_docs.rb
A documentation file can be passed as a positional argument to metasploit-framework/tools/dev/msftidy_docs.rb
and will highlight formatting errors the docs file might contain. Once all the errors and warnings thrown by msftidy_docs.rb
have been resolved, the documentation file is ready for submission.
