Description

MonstraCMS 3.0.4 allows users to upload Arbitrary files which leads to remote command execution on the remote server. An attacker may choose to upload a file containing PHP code and run this code by accessing the resulting PHP file. This module was tested against MonstraCMS 3.0.4.

Module Options

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/monstra_fileupload_exec
msf exploit(monstra_fileupload_exec) > show targets
    ...targets...
msf exploit(monstra_fileupload_exec) > set TARGET < target-id >
msf exploit(monstra_fileupload_exec) > show options
    ...show and set options...
msf exploit(monstra_fileupload_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.
