This module exploits a remote command execution vulnerability in Apache Struts versions < 2.2.0. This issue is caused by a failure to properly handle unicode characters in OGNL extensive expressions passed to the web server. By sending a specially crafted request to the Struts application it is possible to bypass the "#" restriction on ParameterInterceptors by using OGNL context variables. Bypassing this restriction allows for the execution of arbitrary Java 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/http/struts_code_exec
msf exploit(struts_code_exec) > show targets
...targets...
msf exploit(struts_code_exec) > set TARGET < target-id >
msf exploit(struts_code_exec) > show options
...show and set options...
msf exploit(struts_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.
