Module Overview

Name: NETGEAR WNR2000v5 Administrator Password Recovery
Module: auxiliary/admin/http/netgear_wnr2000_pass_recovery
Source code: modules/auxiliary/admin/http/netgear_wnr2000_pass_recovery.rb
Disclosure date: 2016-12-20
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2016-10175, CVE-2016-10176

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 Ranking and Traits

Module Ranking:

normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
