Basic Usage

msf > use auxiliary/admin/networking/cisco_config
msf auxiliary(cisco_config) > show targets
    ... a list of targets ...
msf auxiliary(cisco_config) > set TARGET target-id
msf auxiliary(cisco_config) > show options
    ... show and set options ...
msf auxiliary(cisco_config) > exploit

Required Options

  • CONFIG: Path to configuration to import

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

Knowledge Base

Vulnerable Application

General Notes

This module imports a Cisco configuration file into the database. This is similar to post/networking/gather/enum_cisco only access isn't required, and assumes you already have the file.

Example files for import can be found on git, like this or from Cisco.

Verification Steps

  1. Have a Cisco configuration file
  2. Start msfconsole
  3. use auxiliary/admin/networking/cisco_config
  4. set RHOST x.x.x.x
  5. set CONFIG /tmp/file.config
  6. run

Options

RHOST

Needed for setting services and items to. This is relatively arbitrary.

CONFIG

File path to the configuration file.
