This module exploits a remote code execution vulnerability in the Struts Showcase app in the Struts 1 plugin example in Struts 2.3.x series. Remote Code Execution can be performed via a malicious field value.
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/struts2_code_exec_showcase
msf exploit(struts2_code_exec_showcase) > show targets
...targets...
msf exploit(struts2_code_exec_showcase) > set TARGET < target-id >
msf exploit(struts2_code_exec_showcase) > show options
...show and set options...
msf exploit(struts2_code_exec_showcase) > 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.
