Knowledge Base

Vulnerable Application

General Notes

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

Arista vEOS is available to download for GNS3

Example config file:

! Command: show running-config
! device: aristaveos (vEOS, EOS-4.19.10M)
!
! boot system flash:vEOS-lab.swi
!
transceiver qsfp default-mode 4x10G
!
hostname aristaveos

snmp-server community write rw
!

Verification Steps

  1. Have a Arista configuration file
  2. Start msfconsole
  3. use auxiliary/admin/networking/arista_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.
