Module Overview

Name: ISC DHCP Zero Length ClientID Denial of Service Module
Module: auxiliary/dos/dhcp/isc_dhcpd_clientid
Source code: modules/auxiliary/dos/dhcp/isc_dhcpd_clientid.rb
Disclosure date: -
Last modification time: 2019-03-05 03:38:51 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2010-2156

This module performs a Denial of Service Attack against the ISC DHCP server, versions 4.1 before 4.1.1-P1 and 4.0 before 4.0.2-P1. It sends out a DHCP Request message with a 0-length client_id option for an IP address on the appropriate range for the dhcp server. When ISC DHCP Server tries to hash this value it exits abnormally.

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

msf > use auxiliary/dos/dhcp/isc_dhcpd_clientid
msf auxiliary(isc_dhcpd_clientid) > show targets
    ... a list of targets ...
msf auxiliary(isc_dhcpd_clientid) > set TARGET target-id
msf auxiliary(isc_dhcpd_clientid) > show options
    ... show and set options ...
msf auxiliary(isc_dhcpd_clientid) > exploit

Required Options

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

  • RIP: A valid IP to request from the server
