OpenMediaVault allows an authenticated user to create cron jobs as root on the system. An attacker can abuse this by sending a POST request via rpc.php to schedule and execute a cron entry that runs arbitrary commands as root on the system. All OpenMediaVault versions including the latest release 7.4.2-2 are vulnerable.
Linux,Unix
cmd, x86, x64, armle, aarch64
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/unix/webapp/openmediavault_auth_cron_rce
msf exploit(openmediavault_auth_cron_rce) > show targets
...targets...
msf exploit(openmediavault_auth_cron_rce) > set TARGET < target-id >
msf exploit(openmediavault_auth_cron_rce) > show options
...show and set options...
msf exploit(openmediavault_auth_cron_rce) > 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.
