Netgear DGN2200B pppoe.cgi Remote Command Execution

Description

Some Netgear Routers are vulnerable to an authenticated OS command injection on their web interface. 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. This module overwrites parts of the PPOE configuration, while the module tries to restore it after exploitation configuration backup is recommended.

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/linux/http/netgear_dgn2200b_pppoe_exec
msf exploit(netgear_dgn2200b_pppoe_exec) > show targets
    ...targets...
msf exploit(netgear_dgn2200b_pppoe_exec) > set TARGET < target-id >
msf exploit(netgear_dgn2200b_pppoe_exec) > show options
    ...show and set options...
msf exploit(netgear_dgn2200b_pppoe_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.
