Description

OpenMediaVault allows an authenticated user to create cron jobs as arbitrary users on the system. An attacker can abuse this to run arbitrary commands as any user available on the system (including root).

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